Tens of millions of dollars have been spent on tidal wetland restoration over the past several decades but there is still limited information on the long-term ecological outcomes of these efforts. To address this, a collaborative research project worked with four west coast NERRS and regional partners to assess marsh elevation capital, vegetation communities, and carbon sequestration in 16 decades-old restoration sites and paired reference marshes in California, Oregon, and Washington. By investigating how restoration has affected key wetland attributes at some of the oldest restoration sites along the west coast, this project brings actionable information to restoration practitioners and others planning for, designing, and quantifying benefits of new tidal wetland restoration projects. In this webinar, the project team discusses their results, the implications of their findings for future restoration implementation and monitoring, and next steps.

Abstract: Constraining the causes of past atmospheric methane (CH) variability is critical for understanding links between CH, climate, and terrestrial biogeochemical cycling. Ice core records reveal a 400 ppb CH4 rise across the last deglaciation and more rapid changes during the last glacial period and deglaciation that were synchronous with abrupt climate variations known as Dansgaard"Oeschger (DO) and Heinrich Events (HE). The drivers of these CH variations remain unknown but can be constrained using the CH interpolar difference (IPD), which is sensitive to the latitudinal distribution of emissions, and the stable isotopic composition of CH, which is sensitive to changes in different isotopically distinguishable emission categories (microbial, pyrogenic, and geologic).

We first present a new CH IPD record across the last deglaciation, with substantially improved temporal resolution, chronology, and a critical correction for CH production in Greenland samples. Box model analyses suggest that tropical sources dominated abrupt CH variability, highlighting their sensitivity to abrupt climate change and shifting tropical rainfall patterns. Northern extratropical emissions began increasing ~16,000 years ago, likely via wetland expansion and/or permafrost degradation induced by high-latitude warming, and contributed <25 Tg/yr (45% of the total emission increase) to the abrupt CH rise coincident with rapid northern warming at the onset of DO1.

Next, we present multi-decadal-scale measurements of 13C"CH4 and D"CH4 from Antarctic ice cores and identify abrupt, 1 and 0.5 enrichments in 13C"CH4 synchronous with HE and DO CH4 increases, respectively. D"CH4 varied little across the abrupt changes. Using box models to interpret these data, we propose that abrupt shifts in tropical rainfall associated with HEs and DO Events enhanced 13C-enriched pyrogenic CH4 emissions, and by extension global wildfire extent, by 90"150%. Carbon cycle box modeling experiments suggest that the resulting released terrestrial carbon may have caused one-third to all of the abrupt CO2 increases associated with HEs. These new constraints on deglacial climate"CH4 cycle interactions can improve the understanding of possible present and future feedbacks.

Bio(s): I'm a postdoctoral researcher at CIRES working with the NOAA GML Carbon Cycle Greenhouse Gases group. I study global-scale greenhouse gas dynamics on paleo and modern timescales. I received my PhD from Oregon State University in 2023, which mainly focused on using ice cores to understand the drivers of past atmospheric methane variability and how they were related to corresponding climate changes. I like to spend my free time either outdoors skiing or backpacking, or indoors cooking and playing with my new kittens.

Presenter(s): Lisa Peterson, Fisheries Office of Science and Technology, FIS Program Director and Jennifer Cudney, Fishery Management Specialist with the Atlantic Highly Migratory Species Management Division, Office of Sustainable Fisheries, NOAA Fisheries

Sponsor(s): NOAA Library and NOAA Fisheries

Seminar Contact(s): library.seminars@noaa.gov

Remote Access: https://vimeo.com/event/5098979

Accessibility: Captions are available during the live presentation and once uploaded to the NOAA Library YouTube Channel automatic captions are added. Sign language interpreting services and closed captioning are available, but need to be requested at least 5 days before the event.

Abstract: When individuals or teams encounter a problem while working on a project or initiative, they oftentimes try to solve it through the seemingly most direct path possible. This is often referred to as first-order problem-solving, working around a problem or applying a patch to accomplish an immediate objective without actually addressing the root cause of the problem. This presentation will introduce participants to an approach known as A3 problem-solving, which offers a step-by-step guide for identifying and describing"and fully addressing"the real problem or issue. In addition, the presentation will include demonstrations of tools that can be used to improve processes and thereby enhance outcomes. Finally, this presentation will also demonstrate how a relatively small investment in time can return significant dividends.

Recordings: Recordings will be shared 24 hours after the event on the NOAA Library YouTube channel.

Abstract:
Last September, Hurricane Helene delivered a devastating blow to Asheville, North Carolina, with record-breaking rainfall causing catastrophic flooding, landslides, and unexpected damage to regional infrastructure, water resources, homes, and businesses. The significant road closures, power outages, bridge failure, displacement of communities isolated residents and disrupted essential services. NCSU was closed for nearly a month, and many local businesses took 1-2 months to reopen. The lessons learned are immense, and calls for remarkable resilience for the City, County and individuals like me who witnessed it first hand. Communities have and have had to come together to support each other. NOAA NCEI was one of the many impacted entities that relied on local and City fire departments to support cooling for the data center. The city is actively working on recovery efforts, including data-driven approaches and community collaboration, highlighting the ongoing process of rebuilding and strengthening resilience in the face of climate change.

This presentation discusses my first hand experience, and the role NCICS has been playing with the City and County for wildfire risk assessment, engagement and convening emergency managers for broader preparedness.

Abstract: Trophic interactions operate across the lifetime of an individual organism, yet our understanding of these processes are largely limited to a single life-stage or moment in time. Management and conservation implications of this knowledge gap are particularly acute given the mounting number, spread, and ecological impacts of invasive species. Carbon and nitrogen stable isotopes of animal muscle, for example, are commonly used to characterize the trophic ecology of an individual, but fail to capture intra-individual variation and ontogenetic dietary shifts. However, recent work using eye lenses allows for the reconstruction of individual chronologies recording past trophic positions of and carbon flow to consumers. This study is the first to combine stable isotope analysis of fish eye lens tissue with otolith growth measurements to construct individual lifetime trophic trajectories. We discovered how lifetime trophic trajectories vary within different community contexts and how competition within and between species shifts through ontogeny. Our results provide evidence for dynamic competitive interactions across ontogeny with asymmetric competition between native and nonnative fishes along an invasion gradient in intermittent streams of western Arizona.

Abstract: Ecosystem-based science is a forefront component of effective marine conservation and management. National workshops with ecosystem, human dimensions, and assessment scientists revealed challenges with consistently incorporating ecosystem information in fisheries management decisions. Over the past several years, we have developed a standardized framework called the Ecosystem and Socioeconomic Profile (ESP) for operationalizing the integration of ecosystem and socioeconomic factors within the assessment and advice process. There is now increasing momentum across all NOAA Fisheries regions to produce ESPs or ESP-like analyses, which has inspired the creation of the National ESP Coordination Team to share ESP progress across the science centers and create efficiencies as ESPs are developed. In this presentation we will describe ESPs, their applications and successes to date, and key activities supported by the National ESP Coordination Team.

Recordings: Recordings will be shared 24 hours after the event on the NOAA Library YouTube channel.

Abstract: The coastal ecosystems that support fisheries are undergoing rapid change. Temperatures are increasing and oxygen levels are decreasing; in theory, these two trends simultaneously constrain marine life because increased temperatures increase oxygen demand while declining oxygen levels decrease supply. Identifying the consequences of these changes on fish distribution has been an ongoing focus of research to anticipate impacts on fisheries management. We evaluated joint temperature and oxygen sensitivities for over twenty groundfish species of commercial, cultural, and ecological importance in the northeast Pacific Ocean, from Alaska through southern California. We combined data from the NOAA West Coast, Gulf of Alaska, and Eastern Bering Sea bottom trawl surveys, the DFO British Columbia synoptic bottom trawl surveys, and the International Pacific Halibut Commission fishery-independent set survey from 2003"2024 with co-collected observations of temperature and oxygen. Data were fit to coastwide spatio-temporal statistical models that included oxygen as a physiologically based metric that considers the effect of temperature on oxygen tolerance (i.e. the metabolic index). For this work, we also developed a method to estimate the temperature-sensitivity of oxygen directly from distribution data (recently published) and skill tested different sources of oxygen data (global oceanographic model output, interpolations from integrated statistical models of compiled oxygen observations, and co-collected in situ data) (in review). Overall we found some support for a limiting effect of oxygen on distribution in certain species and identify species and regions that may be vulnerable to future decreases in dissolved oxygen. However, there are still sources of uncertainty that are hindering estimation. Further efforts to combine insights from physiology and realized species distributions and expanding transboundary data availability and prioritizing ocean oxygen measurements will improve forecasts of species' responses to future environmental changes.

Title: Green-up in the Alaska Boreal Forest

Presenter(s): Rick Thoman (Alaska Center for Climate Assessment and Policy), Jan Dawe (OneTree) and Susan Harry (University of Alaska Fairbanks)

Sponsor(s): NOAA/OAR/Climate Program Office and the Alaska Center for Climate Assessment and Policy (ACCAP)

Seminar Contact(s): Alison Hayden (abhayden@alaska.edu) & Genie Bey (genie.bey@noaa.gov)

Remote Access: https://uaf-accap.org/event/green-up-2025/

Abstract: Spring in Alaska means important happenings in the boreal forest. Sap starts flowing in birch trees, leading to tapping and turning the sap into delicious treats. Green-up, when leaves burst forth from Alaska's deciduous trees, has important implications for the seasonal ecology, society and even meteorology in the state. It is rapidly followed by pollen release, which is a health issue for many Alaskans. Fairbanks has a unique multi-decadal record of green-up dates that's been used to develop a technique for forecasting green-up and related events in the Interior and more broadly in the boreal forest regions in Alaska. This webinar will be the sixth annual review of the green-up forecasting tools and will provide a look-ahead at green-up for Spring 2025. One Tree will demonstrate citizen science-outreach tools for birch tappers and others.

Bio(s): Jan Dawe is a Research Assistant Professor of Natural Resource Education and Community Engagement with the Alaska Agricultural and Forestry Experiment Station at the University of Alaska Fairbanks. She is currently the director of OneTree Alaska and K-20 STEAM Education, which has a mission to engage learners of all ages in boreal forest education, citizen science, and forest product development. Jan enjoys sharing her interests in botany and phenology (the study of the timing of recurring events in an organism's annual life cycle) and appreciates working with Rick Thoman and others to discover how the Green-Up Forecast might be used to predict other spring phenomena-such as the initiation of birch sap flow, onset of birch pollen season, and more!
Susan Harry is the Department of Veterinary Medicine's Laboratory and Safety Coordinator at the University of Alaska Fairbanks. She has over 30years of experience in the medical laboratory field. Susan had the opportunity to train under the late Dr. James H. Anderson, former biosciences librarian for UAF. Under his guidance, she developed the skill of counting local pollen and began sharing this valuable information with the local community in 2000. The data has proven valuable not only to allergy sufferers but the scientists worldwide studying climate change. Susan continues to provide the count through One Tree Alaska and UAF's Institute of Agriculture, Natural Resources and Extension.Rick Thoman is the Climate Specialist at the Alaska Center for Climate Assessment and Policy. He has many years of experience producing reliable Alaska climate change information describing Alaska's changing environment. His work spans the bridge between climate modeling, Alaska communities, and the media.

Accessibility: Captions are available during the live presentation and once uploaded to the NOAA Library YouTube Channel automatic captions are added. Sign language interpreting services and closed captioning are available, but need to be requested at least 5 days before the event.

Abstract: In this webinar we share research that examines how and what types of curriculum support materials help teachers implement citizen science projects in elementary school classrooms. Working with teachers, our team designed educative curriculum materials for Community Collaborative Rain, Hail, and Snow (CoCoRaHS) and Lost Ladybug Project (LLP) that are designed to support both teacher and student learning. We collected data from teacher and student participants across North Carolina, and our preliminary findings indicate that teachers who have educative support materials designed for a citizen science project are more likely to include citizen science with their students than when they only have access to the project's website. We will further share what we have learned about the types of supports teachers use most and their contributions to students' authentic science experiences.

Recordings: Recordings will be shared 24 hours after the event on the NOAA Library YouTube channel.

Abstract: Persistent declines in red king crab (Paralithodes camchaticus) abundance in Bristol Bay, Alaska, have triggered recent fishery closures and heightened interest in conservation measures for the stock. However, fisheries-independent data are only collected in the summer, and this lack of seasonal distribution data in non-summer months hampers the evaluation of proposed management actions that target Bristol Bay red king crab (BBRKC) bycatch in groundfish fisheries active in the fall, winter, and spring. We addressed this issue by developing species distribution models for BBRKC using fisheries-dependent data as a step towards understanding factors regulating BBRKC spatial dynamics in non-summer months and improved scientific advice for management. Our specific objectives were to model BBRKC: 1) legal males in the fall; and 2) bycatch in non-pelagic trawl (NPT) groundfish fisheries during peak bycatch seasons (September-October, January-February, and April-May). For the first objective, we used BBRKC summer bottom trawl survey data, temperature, depth, sea ice cover, sediment grain size, maximum tidal current, current, and slope as covariates. For the second objective, we used the same covariates (except for current and slope) along with flatfish summer bottom trawl survey CPUE, and flatfish fishery CPUE, quotas, and gear changes. For both objectives, we trained Boosted Regression Tree SDMs and evaluated out-of-sample predictive performance. Model evaluation metrics indicated good to excellent predictive ability for both objectives. For bycatch distribution, we found that flatfish directed-fishery CPUE, summer survey CPUE for BBRKC and flatfish, and depth were important predictors and physical variables were generally less important. We also found strong correlations between the mean latitude of observed bycatch and the summer survey for BBRKC, highlighting the ability of summer survey data to predict non-summer bycatch distributions. For legal males in the fall, we found that spatial distribution was driven by bottom temperature, BBRKC summer survey distribution, depth, and tidal current. For this objective, we also found that distribution hotspots generally aligned with existing closure areas but shifted with temperature, suggesting the utility of static closure areas may change over time. These models are the first dynamic predictive tools to evaluate BBRKC distribution in data-poor periods and represent an important step towards operating models that may be used to evaluate proposed management actions.

Abstract: Along the continental shelf edge in the northwestern Gulf of Mexico, Flower Garden Banks National Marine Sanctuary protects a series of unique topographic features that support diverse fish assemblages. Mesopredators play a vital role in structuring reef ecosystems, yet their movement patterns, habitat use, and competitive interactions with invasive mesopredators are poorly understood within the sanctuary. This study employs acoustic telemetry and biophysical modeling to investigate habitat preferences, site fidelity, and connectivity between reef features, as well as examining how the invasive lionfish is integrating into the native community. The results from this project aim to provide critical insight on habitat use that will enhance ecosystem resilience and effective resource management while exploring the effectiveness of current sanctuary boundaries.

Title: A practical approach for integrating eDNA into stock assessment and fishery management advice

Part of the NOAA Omics Seminar Series

Presenter(s): Diana Baetscher, Research Geneticist, NOAA Alaska Fisheries Science Center

Sponsor(s): NOAA Omics

Seminar Contact(s): Nicole Miller, NOAA 'Omics Portfolio Specialist, noaa.omics@noaa.gov

Remote Access: Register Here

Abstract: Of the many types of omics data, environmental DNA (eDNA) may present the biggest opportunity for developing quantitative estimates of relative abundance trends, a key input for stock assessment models. However, eDNA has yet to be widely adopted within fisheries management frameworks, largely given the skepticism that many scientists have towards new and evolving methods. We address key challenges that have limited eDNA from being incorporated into fisheries management frameworks and propose a roadmap for using eDNA in multiple types of stock assessment models. A primary impediment to operationalizing eDNA is the lack of interdisciplinary research teams, including geneticists, stock assessors, and other fisheries scientists and managers, which are necessary to interpret methods and results across scientific disciplines and ensure data are being used appropriately.

Bio(s): Diana leads the environmental DNA research at AFSC in Juneau, Alaska. Her projects apply genetic methods to a range of ecological and fisheries management questions, including population genetics of rockfishes and seabirds, and foraging ecology and diets of Northern fur seals. Diana started in her role at AFSC in 2021.

Abstract: Tropical cyclones are already difficult to forecast and become an even bigger challenge when wind shear affects their development. Work done on tropical cyclone development under shear involves the use of idealized simulations, observational data from reconnaissance flights in real storms, and model data with real cases. My work will focus on using the Hurricane Analysis Forecast System (HAFS) model to assess tropical cyclone vortex tilt and investigate what processes lead to alignment"and intensification"of areal-world case, Hurricane Laura (2020). Such systems involve a build-up of convective processes from the low-level vortex to the mid-level vortex, ultimately strengthening the vortex of the storm and intensifying into a mature hurricane.

Bio(s): Luis Hernandez is a NCAS-M II Cohort 2 fellow earning a PhD in the Department of Atmospheric Science at University at Albany-SUNY, New York. This work resulted from the NERTO internship project conducted with NOAA mentors, Dr. Ghassan Alaka and Dr. Michael Fischer of the NOAA/AOML National Hurricane Division, Miami, FL. His NERTO, Investigating the Relationship Between Tropical Cyclone Rapid Intensification and Vortex Alignment, aligns with NCAS-M II's research pathway: Improved quantification of forecast skills for weather, water, air-pollution, and extreme events. The project also deepened Mr. Hernandez's understanding of NOAA and expanded his competencies to conduct research and engage in NOAA mission-aligned activities.

Abstract: There is a significant gap in understanding the physical processes in tropical cyclones, leading to inaccuracies in numerical weather prediction (NWP) models and forecast uncertainties. To address these, forecasters use multiple models to improve guidance. Conducting physics sensitivity experiments in NWP models helps identify biases and enhance probabilistic forecasts. The Hurricane Analysis and Forecasting System (HAFS) is NOAA'snext-generation ocean-atmosphere-coupled model and data assimilation system. HAFS aims to provide reliable forecasts of tropical cyclone (TC) track, intensity, size, genesis, storm surge, rainfall, and tornadoes, within the Unified Forecast System (UFS). Hurricane Ian (2022) developed from a tropical wave in the Eastern Caribbean and was classified as a tropical depression on September 23. It became a tropical storm the next day and rapidly intensified on September 25. By September 26, Ian intensified quickly due to warm waters and low wind shear. It reached Category 5 strength by September 28 and made landfall in Southwest Florida. Forecasts of Ian's track and intensity, especially on September 24, were uncertain, complicating landfall predictions. This study used a mini-ensemble of HAFS simulations with different physics parameterization schemes to better understand the uncertainties in predicting Hurricane Ian's behavior.

Bio(s): Myah Rather is a NCAS-M II Cohort 2 fellow earning a PhD in the Howard University Graduate Program in Atmospheric Science. This work resulted from the NERTO internship project conducted with the NOAA mentor, Dr. Sundararaman Gopalakrishnan of the NOAA/AOML National Hurricane Division, Miami, FL. Her NERTO, Impacts of HAFS Physics Sensitivities on Track, Intensity, and Structure Prediction of Hurricane Ian, aligns with NCAS-M II's research pathway: Improved quantification of forecast skills for weather, water, air-pollution, and extreme events. The project deepened Ms. Rather's understanding of NOAA and expanded her competencies to conduct research and engage in NOAA mission-aligned activities.

Title: Filling Gaps on Maps with High Resolution Modeled Water Levels and Waves through NOAA's Coastal Ocean Reanalysis (CORA)When: April 23 2025, 11 AM-12 PM ET Where: Webinar

Presenter(s): Analise Keeney, Coastal Hazards Oceanographer, NOAA

Seminar Contact(s): Varis.Ransi@noaa.gov

Remote Access: Register here or https://noaabroadcast.adobeconnect.com/anakeeney/event/registration.html

Abstract: NOAA's Center for Operational Oceanographic Products and Services (CO-OPS) maintains and operates the National Water Level Observation Network (NWLON) to provide real-time and historic water level observations at over 200 locations across U.S. coastlines. While NWLON stations provide crucial data for floodplain managers, their insights are restricted to areas near these gauge locations. This limitation makes it challenging to assess the full range of coastal flooding impacts between stations, which can be as far as 100 miles apart in some US regions. Gaps in coverage can make it especially difficult for underserved communities to access necessary information for monitoring flooding where they live. NOAA's Coastal Ocean ReAnalysis (CORA) seeks to bridge these observation gaps by combining existing water level measurements with hydrodynamic modeling. ADCRIC and SWAN are used to produce high-resolution historical water level information. NWLON water level observations are assimilated by CORA to produce a 40+ year time series of hourly water levels and waves every 500m. A skill assessment conducted by the University of Hawaii's Sea Level Center (Rose, et al, 2024) found that the CORA-derived hourly and monthly water levels well represent the NWLON observations in the Gulf, Atlantic, and Caribbean. CORA datasets for the Gulf of Mexico, Atlantic, and Caribbean are publicly accessible through NOAA's Open Data Dissemination (NODD) platform, and available in multiple, geospatially-compatible formats to support both research and product development. Next steps will focus on integrating CORA datasets into prototype flood risk assessment and mitigation services, to equitably provide coastal communities with valuable historical information for coastal planning. This presentation will illuminate the need for modeled historical water level between tide stations, the collaborative community modeling approach to development, and the ways CORA enhances the richness of NOAA's authoritative oceanographic datasets to support coastal resilience and risk mitigation.

Bio(s): Analise works as a coastal hazards oceanographer in NOAA's Center for Operational Oceanographic Products and Services (CO-OPS). She engages with partners to develop geospatial products that aid decision-makers in lessening the effects of persistent sea level rise because of climate change. CO-OPS is the nation's authoritative source for accurate, reliable, and timely data for tides, water levels, currents, and other coastal oceanographic and meteorological information. The office maintains over 200 permanent water level stations on the U.S. coasts and Great Lakes, a system of real-time sensors concentrated in busy seaports, and temporary meters that collect observations for tidal current predictions. Through these systems, NOAA provides the nation with historical and real-time data, forecasts, predictions, and scientific analyses that protect life, the economy, and the coastal environment.

Abstract: Investigating parturition and pupping patterns can inform our understanding of yearly recruitment expectations and population fluctuations. Steller sea lions (Eumetopias jubatus) were listed as endangered in 1990 due to a dramatic decline in population abundance. The abundance of the western distinct segment is still decreasing and therefore has retained its endangered status. To gain insights about age-specific parturition and temporal patterns in pupping and survival, we examined data from a 17-year longitudinal study of Steller sea lions on Ugamak and Marmot Island rookeries, Alaska. Marking of Steller sea lions at these rookeries has occurred since 2000 and inference was based on a multi-state hierarchical model that accounted for uncertain observations concerning the reproductive status of females. Our analysis indicated a high probability for adult female Steller sea lions to pup annually from age 6 until around 15 years of age; rates for younger (but still sexually mature) females were much lower. Parturition probability was highest during the first half of June and declined steadily to the first week of July across all ages and rookeries, supporting previous research conducted at the same locations. Most observations concerning the reproductive status of adult female Steller sea lions were ambiguous (e.g., lying next to a pup vs. nursing a pup), highlighting the importance of a model-based approach that rigorously addresses uncertainty in mother-pup associations. Overall, these data further our understanding of pupping patterns, which will assist in future research investigating potential drivers of continued declining abundance in certain Steller sea lion populations.

Abstract: This study focuses on the dynamics of the Planetary Boundary Layer (PBL) in the western CONUS, a region characterized by complex mountainous terrain and heterogeneous land surface types. Leveraging Aircraft Meteorological Data Reports (AMDAR) and High-Resolution Rapid Refresh (HRRR)model outputs, we investigate the evolution of the PBL and its interaction with both topography and underlying surface conditions. Our methodology includes analyzing AMDAR-derived potential temperature profiles near nine western U.S. international airports and comparing them with HRRR estimates to diagnose PBL characteristics. Special emphasis is placed on evaluating the influence of surface type (e.g., urban, arid, vegetated) on PBL height, accounting for the potential advection of air masses away from their source regions. Through temporally and spatially averaged composites of wind speed, potential temperature, and other key thermodynamic variables, we identify systematic differences in PBL evolution across surface types and terrain complexity. Preliminary results show skillful predictions in near-surface fields but reveal persistent biases in PBLH over complex terrain and certain surface categories. These findings foreshadow the contribution and importance of integrating land surface variability in PBL diagnostics and model evaluation, with implications for improving boundary layer representation in mountainous regions.

Abstract: NOAA's Fire Weather Testbed is a joint endeavor between the Office of Oceanic and Atmospheric Research (OAR), the National Weather Service (NWS), and the National Environmental Satellite, Data, and Information Service (NESDIS) to enhance decision support during all phases of the fire cycle. In June of 2024, OAR's Global Systems Laboratory facilitated the second evaluation of the testbed. Four NWS meteorologists and five state land managers participated in a week-long experiment assessing the utility of the Next Generation Fire System (NGFS) and Integrated Warning Teams (IWT) for Fire Warnings in their fire operations. This project highlights the analysis of two semi-structured focus groups conducted at the end of the evaluation. Participants were separated into occupation-based focus groups and asked a series of questions related to the performance, feasibility, and cohesiveness of each product. Each focus group was recorded and thematically coded. Our preliminary findings revealed that both meteorologists and land managers saw the potential benefits of incorporating these tools into their fire operations and collaborating with one another during wildfire events. As wildfires continue to intensify, it is becoming increasingly important to tailor decision support services to user needs and encourage interagency partnerships to address them.

Abstract: The Matagorda Bay System, avital Texas estuary, supports marine habitats, acts as a coastal barrier, and filters pollutants, but is vulnerable to non-point source pollution. This study evaluates if sediment contamination contributes to ecosystem degradation or benthic organism decline using a Sediment Quality Triad (SQT) approach. Thistriad includes chemical analysis, toxicity tests, and benthic diversity assessment. Nineteen stations across the Matagorda Bay system were sampled, alongside a control from Leadenwah Creek, SC. Survival analysis revealed the lowest survival rates were from stations located in the upper portions of Lavaca Bay and Tres Palacios Bay. Results of the chemistry analysis show mercury poses the highest contamination risk, with moderate risks from polychlorinated biphenyl (PCBs), arsenic, and nickel at some sites. This research contributes to the ongoing efforts to mitigate pollution in Texas bays, supporting the health of local fisheries and sustaining the economic benefit of recreational and commercial fishing. NOAA mentor Dr. Marie DeLorenzo of the National Ocean Service supported this internship to address issues within marine and coastal communities, insights into the impacts of contaminants on these ecosystems, and helping in the development of strategies for ecosystem restoration, protection, and pollution mitigation.

Abstract: The role of natural infrastructure, like wetlands and oyster reefs, in protecting cultural resources in Baltimore, MD, from climate change and coastal erosion was studied. Cultural resources, including arts and entertainment districts, places of worship, and historic places, were analyzed alongside spatial data on natural and gray infrastructure. Using Geographic Information System (GIS), the analysis determined that wetlands provide the highest level of protection, with 41.06% of cultural resources located within a200-meter buffer. In contrast, contemporary oyster infrastructure safeguards only 0.48% of cultural resources within the same range, highlighting the loss of these once-critical natural buffers. The findings underscore the importance of wetlands as a resilient natural infrastructure, to conserve and manage coastal ecosystems while promoting community resilience. This project is a NERTO graduate internship conducted with mentor Dr. Amy Freitag of the National Ocean Service. The research aligns with the NOAA CCME-II's emphasis on place-based conservation and provides actionable insights for integrating cultural preservation and environmental restoration in urban resilience planning. This work was in response to community requests, reflecting their priorities and concerns about preserving cultural heritage and mitigating risks.

Bio(s): Bria Pope is a second-year master's student in Environmental Science at Florida Agricultural and Mechanical University (FAMU), where she is a NOAA Center for Coastal and Marine Ecosystems (CCME-II) Cohort #3 Graduate Scholar.

Abstract: The Cold Regions Research and Engineering Laboratory's (CRREL) Ice Jam Program and Database began in 1992 as a means of cataloguing and analyzing river ice-related flooding problems. Rivers in the northern United States are subject to ice jams that cause flooding, interfere with hydropower and water supply intakes, impede navigation, damage riverine infrastructure, and decrease downstream discharge. Our mission is to document and report on these events and serve as a resource for emergency managers and planners trying to understand the risks and potential mitigations of said events. We utilize a variety of data sources to identify and evaluate jams, including Weather Service reports, USGS and local gauge data, CPC forecasts, optical and microwave satellite remote sensing, in-situ cameras, firsthand accounts, as well as news outlets and social media. We will discuss some use cases and applications of this dataset, some practical limitations and bias inherent to the process and their impacts, our plans to enhance our operational detection and record-keeping capabilities moving forward, and aspirations of improving our predictive capabilities by including research products to describe ice thickness, frazil ice production, infrequent storm and rain-on-snow risk, and to work towards a more comprehensive risk model.

Estuaries are complex seascapes encompassing multiple habitat types that support critical nursery functions for shrimp and other commercially-harvested species. Shrimp reside in estuaries during multiple life-stages and, because shrimp life history occurs on an annual scale, populations are sensitive to changes in environmental conditions and available habitat. Commercial shrimp landings have been variable over the past two decades, and the effects of environmental factors on shrimp abundance remain unclear. There is therefore a need to better understand changes in shrimp populations in response to environmental variability due to changing climate conditions, weather events, and habitat modifications.In this webinar, the Lowcountry Shrimp Collaborative team " which spans universities, fishery management agencies, fisheries extension offices, and NERR sites " will present results from their project, which used a multi-faceted research framework to better understand the importance of different estuarine habitat types and variable environmental conditions on shrimp populations. Join the session to learn more about the team's approach, which utilized ongoing, long-term biological surveys within estuaries across South Carolina and Georgia, new data collection in the field and lab, and interviews with shrimp industry end-users to better understand the effects of varying environmental conditions on shrimp population dynamics and the associated shrimp fishery.

Title: What the Salar de Uyuni, the world's largest salt flat, has taught us about satellite radar altimetry of water heights over lakes and riversSTAR Science Seminars

Presenter(s): Ron Abileah, jOmegaK, San Carlos, CA

Sponsor(s): Center for Satellite Applications and Research

Seminar Contact(s): walter.hf.smith@noaa.gov

Abstract: Early experiments with coherent processing of satellite altimeter pulse echoes demonstrated that water heights could be measured at lakes and rivers by treating these as small specular surfaces. Applying these techniques to the Salar de Uyuni in Bolivia, the world's largest salt lake bed, turned up a number of fascinating puzzles. In the rainy season the Salar is a water surface extending over an area so much larger than the altimeter's field of view that the altimeter should see it the way an altimeter sees an ocean; yet the Salar acts as if it were a mirror-like surface of effectively infinite extent, apparently unrippled by any wind waves. How can this be? The radar cross section (RCS) calculated theoretically by assuming the Salar to be an infinite mirror initially seemed to not quite match the empirical RCS sensed by the altimeter, but this paradox may now be resolved. This talk will present these issues and the highlights of a field trip to the Salar the presenter made to gather in situ data to address these issues. Some intriguing enigmas remain, and these will be presented also.Ron Abileah is a highly creative thought leader with decades of experience consulting for government agencies on various topics requiring that inferences be drawn from remote sensing. Specifically in the area of satellite radar altimetry, he has been one of the leaders in the application of altimetry to the measure of inland water surfaces.

Abstract: Communication allows social species to exchange important information among group members, such as individual or group identity, predator presence, movement decisions, or the location of prey. In aquatic environments, acoustic signals are among the most effective forms of communication, primarily for cetaceans. Beluga whales, Delphinapterus leucas, are highly social and vocal, yet little is known about the functionality of their social calls. To examine context-dependent vocal behavior in beluga whales, we collected passive acoustic data and fine-scale behavioral observations for the endangered Cook Inlet population. The resulting dataset includes 1,720 annotated vocalizations collected during 1,051 minutes over 21 behaviorally encoded encounters. We fit two mixed models to investigate the effect of group behavioral state, group size, calf presence, and tidal state on 1) calling rate (number of calls/minute) and 2) call category (whistles, pulsed calls, or combined calls). Calling rate is affected by group behavioral state, group size, and tidal state: belugas are more likely to call during travel and as group size increases and have higher calling rates with larger group sizes and during flood tides. Call category is affected by group behavioral state and calf presence: whistles are more prevalent when traveling, pulsed calls are more prevalent when milling, and combined calls occur only when calves are present. We also provide a descriptive analysis of vocal activity in relation to behavioral transitions, which suggests an increase in calling rate leading up to behavioral transitions. Understanding the connections between behavioral, social, and environmental factors on vocal communication can provide ecological insights into the functional roles of acoustic signals in social cetaceans and social species more broadly.

Accessibility: Captions are available during the live presentation and once uploaded to the NOAA Library YouTube Channel automatic captions are added. Sign language interpreting services and closed captioning are available, but need to be requested at least 5 days before the event.

Abstract: The Suwannee River is among the Florida locations with the most potential for Paleoindian site occurrences. We used remote sensing to map the seafloor in an area suspected to be the Paleo-Suwannee River Channel, which revealed relict dunes and oyster reef complexes. Archaeological dives were also performed to document and sample the seafloor. The sediment composition from the hypothesized Paleo-Suwannee channel was characteristically different from the cores extracted outside the channel zone, forming dateable soil horizons that can be used to determine the relict course of the river. In many locations, an extensive oyster bioherm that would have supported human occupation was covered with marine sediment. However, no cultural materials nor human burials were located.

Recordings: Recordings will be shared 24 hours after the event on the NOAA Library YouTube channel.

Abstract: Particles in the atmosphere are important for different reasons in different parts of the world. In areas where there are a lot of humans, they are important because of their adverse effect on human health and reduction in visibility. In the remote troposphere, they have a large impact on the brightness and longevity of clouds. In the stratosphere, they can cause ozone destruction and potentially change large scale circulation. And in all locations, they interact with solar radiation, often scattering some light back into space, temporarily masking the warming effect of CO2.

In this talk I will present the results from two airborne field campaigns connecting microphysical and optical measurements of particles. The first field campaign, FIREX- AQ, was focused on wildfires emissions. Smoke from wildfires is important because of the expectation of increasing wildfires, but also due to its historical contribution to a pre-industrial climate. I will present in situ measurements of the aerosol optical properties that show that fresh wildfires smoke scatters approximately 20% more light into space than conventional models would predict. This is important for both radiative forcing
estimates and for remote sensing techniques that use the light scattered into space to
infer wildfire smoke emissions.

The second airborne field campaign, AEROMMA, was focused on urban emissions, but was also heavily influenced by a severe wildfire season. This work is in progress and being led by Dr. Han Huynh. The goal is to create a comprehensive and validated model of aerosol composition and optical properties in and around large American and Canadian cities. The purpose of this model is a) to evaluate common assumptions about how aerosols are represented in models and b) provide a comprehensive dataset
for validating remote sensing retrieval algorithms. The data that was collected and used in this model coincides with the newly operational TEMPO satellite, but we hope that by converting in situ measurements into parameters and formats that are accessible to the community, we can provide value to a wide range of modelers and remote sensing algorithm developers.

Bio(s): Adam Ahern is a research scientist with CIRES in the NOAA Chemical Sciences Lab. He specializes in airborne measurements of atmospheric particles from various sources. Measurements of aerosol microphysical (e.g. number and size) and optical (light scattering intensity and direction) are important for understanding the effects of atmospheric particles on the global radiation budget and for correctly interpreting aerosol measurements made by satellites.

Title: A Brief History of OISST Analysis (i.e., The Reynolds Analysis)
CoastWatch Seminar Series

Presenter(s): Thomas Smith (NOAA NESDIS/STAR)

Sponsor(s): NOAA CoastWatch


Seminar Contact(s): Rebecca.Trinh@noaa.gov

Remote Access:

Abstract: The optimum interpolation (OI) sea-surface temperature (SST) analysis was developed and improved over a number of versions starting in the early 1990s. There is a demand for a satellite-based SST analysis with global coverage for weather and climate studies, including model simulations, and for monitoring global environmental conditions. The original analysis was 1-deg and weekly. The 0.25-deg daily OISST was first developed in the late 2000s and has been gradually updated and improved since. The presentation gives an outline of the analysis development history up to the present.

Bio(s): Thomas Smith is a physical scientist with NOAA/STAR. His education includes degrees in mathematics, meteorology, and oceanography. He began working at NOAA as a UCAR post doc in 1990, and then joined NOAA/CPC in 1991 where he began working with Richard Reynolds on SST analysis. He also worked with Reynolds at NOAA/NCEI, and has continued to work with the SST group since joining STAR.

Abstract: Synoptic to sub-seasonal variability of currents in the southern Sea of Japan/East Sea (JES) was investigated using high-resolution current measurements collected at multiple acoustic Doppler current profiler (ADCP) moorings deployed during MJES (Mixing in the Japan East Sea, 2021-2022) and LINKS (Linkages of Asian MarginalSeas, 1999-2000) programs. MJES measurements were collected over the slope of thesouthern Ulleung Basin (UB) and near the southeastern coast of Korea, and LINKSmeasurements were collected within the Korea-Tsushima Strait (KTS). Observationsshow synoptic to sub-seasonal velocity fluctuations in the southern Korean coastalregion to the southern slope of the UB. Velocity fluctuations observed during March "June 2022 had magnitudes as large as 0.3 m s -1 with a broad period of 10-15 days.Winds and coastal currents were highly correlated and had a coherence of 0.95 at a12"13-day period and a 2.7-day lag. Similar velocity fluctuations were registered atmoored ADCP records on the southern boundary of UB and the northwestern corner ofKTS, but there were no significant correlations between winds and currents. However,atmospheric surface-pressure distributions over the JES show 10-15 day oscillatingalong-basin pressure gradients of magnitudes 10 -5 mb m -1 . Our analysis suggests thatapart from wind forcing over the shelf, the atmospheric pressure-gradient forcing can bean important forcing mechanism for generating the observed velocity fluctuations in thesouthern JESSlides, Recordings, OtherMaterials: TBDSubscribe to the NOAA ScienceSeminar Series weekly email: Sendan e-mail to OneNOAAscienceseminars-request@list.woc.noaa.gov with the word 'subscribe' in the subject or body.Visit the NOAA Science Seminar Series website for more information.

Meeting password: 2025AFSC

Abstract: Fisheries observer programs represent a type of long-term ecological monitoring program (LTEM), and as such employ varied quality assurance (QA) and quality control (QC) methods to ensure data vital to sustainable fisheries management is of the highest quality. In the North Pacific Observer Program (NPOP), a significant element of the QA/QC chain is the final debriefing, an interview between trained, highly knowledgeable staff (a.k.a., debriefers) and fisheries observers returning from deployment. The purpose of the interview is to review all collected data to ensure compliance with collection standards and quality guidelines. To understand the impact of final debriefings on data quality in the NPOP, we summarized trends in how, where, and why debriefers deleted data during the interview stage from 2014-2023. We summarized deletions by calculating the percent of available data deleted by debriefers within the covariates of time (year), vessel class and gear type (as groups), observer experience (approximated by number of prior cruises), whether observers were deployed alone or with other observers to a vessel, and by deletion causes attributed by debriefers upon deletion. Our findings suggest debriefers in the NPOP rarely delete data en masse. The value of debriefing appears through the removal of biased or incorrectly transcribed data, especially aboard vessels fishing pot gear, and for observers with little experience and when deployed as the sole observer on a trip. These summaries demonstrate how debriefing acts as a vital component of fisheries observer programs to maintain high quality standards.

Abstract: The National Stock Assessment Program (NSAP) supports, advocates for, and improves stock assessment science and operations in NOAA Fisheries. We foster connections within the stock assessment community, help integrate innovations into operational use, develop and support tools that bolster fisheries management, and serve as a conduit between regional programs and agency priorities. We track stock assessment performance, support making stock assessments more holistic, provide training and opportunities for the current and next generation of stock assessment scientists, and build software tools. Open communication is key to ensuring this work meets its intended aim to serve the stock assessment community. However, our community is broad, regionally diverse, and busy, making implementation challenging. In this seminar I'll share several projects that NSAP staff are coordinating, the rationale for our focus on these projects, and how partners can contribute and provide feedback.

Abstract: In the last two decades, there have been dramatic changes in the availability of man-made structures in the Gulf -- the number of oil and gas platforms has fallen sharply, while artificial reefs, including reefed rigs has increased. Our multi-year NOAA-funded project explores the ecological and economic consequences of these changes for the recreational fisheries. We found that the ecological function of oil and gas platforms differ across the Gulf in terms of the communities of fish that they support, the occupancy and abundance of key fished species, and their role in connectivity and recruitment dynamics. As a whole, these structures provide habitat for millions of fish and contribute useful functions to the populations of species that are valuable to recreational fisheries; however, conditions specific to each platform likely require decommissioning decisions to be made case by case to understand the ecological implications. Economically, using data that tracks where anglers actually go fishing, we find that anglers are willing to travel substantial distances, incurring extra costs in fuel and time, to reach a location where there is a platform. This indicates that they place substantial value on these platforms.

The Mangrove Coast Collaborative (MCC) project (2020 " 2024) began in the aftermath of Hurricanes Irma and Maria (September 2017). Jobos Bay and Rookery Bay NERRs jointly recognized the need to understand and enhance the resilience of their mangrove ecosystems and the surrounding communities in southeastern Puerto Rico and southwest Florida, respectively. Through a multi-disciplinary approach spanning four research themes " time-series mapping, ecosystem assessment, ecosystem services modeling, and management options " the MCC investigated the loss and recovery of mangroves, the relationships between drivers of hurricane impact and recovery, the effects to ecosystem services, and the ways that managers have made information-based decisions. Using co-production methods, the project team developed and shared products at a recent regional Mangrove and Management Forum that brought together a newly coalescing community of mangrove scientists and managers in the southeastern US and Caribbean.In this webinar, the project team will describe how the mangrove science-to-management community developed as an integral part of the MCC and will share an overview of how the ongoing results of the MCC have responded to the needs of this growing community.

Abstract: Projections of population dynamics are theunderpinning of scientific fisheries management. These typically includeestimates of population processes conditioned on historical data, and a methodto represent the management action (i.e., fishing quota) and its impact on the population. Theweight-at-age of individual fish in the population or fishery has a strongimpact on derived management quantities in Alaska, yet is often projectedforward using a simple five-year average. This introduces the risk of bias inour assessment projections when true weight-at-age is higher (leading toforegone catch) or lower (leading to over-exploitation) than projected. Thougha variety of methods have been proposed to estimate and project weight-at-age,the nature of the assessment cycle precludes rigorous simulation testing ormethod updates after the stock assessment has been completed.

Abstract: The arctic-boreal region is carbon dense, with about one third of global soil carbon stored in permafrost affected soils. As global temperatures rise, the arctic-boreal region is warming at a rate two to four times higher than the global average, making this region particularly vulnerable to rapid changes. It is estimated that by the end of the century, carbon emissions of carbon dioxide and methane from this region will be equal to that of a major industrialized nation, emitting between 30 and 150 billion tons of carbon as permafrost thaws. Despite the potential impacts on global climate, the arctic-boreal region has a relatively sparse monitoring network with only about 20% of the region being represented by monitoring sites for year-round carbon dioxide and methane. As a part of a project called Permafrost Pathways, we aim to fill these data gaps and better constrain and understand carbon fluxes from the arctic-boreal region. We use a statistical approach using a distance measure to find the best locations for new and upgraded eddy covariance tower sites. Thus far, we have installed new sites on the Seward Peninsula in Alaska, in the Hudson Bay Lowlands, and in the Canadian High Arctic. Additionally, we have opportunistically rebuilt a tower (Scotty Creek) that burned down in a fire in 2022 as well to have a rare before and after fire flux record in collaboration with researchers at the Universite de Montreal. We are using these data and more to synthesize flux records across the arctic-boreal region and upscale fluxes of carbon dioxide and methane over time. We find that the boreal region is an increasing carbon dioxide sink with some tundra regions switching to a source over the past two decades. However, when fire is accounted for, the sink is much weaker for the whole region and boreal region is no longer an increasing sink.

Bio(s): Dr. Arndt studies greenhouse gas and energy fluxes using eddy covariance, primarily working in the arctic-boreal region. He is currently working to expand the eddy covariance flux network across the arctic-boreal region to measure under represented ecosystems to better upscale and model the carbon balance. He received his PhD in ecology from the Joint Doctoral Program in Ecology from San Diego State University and the University of California, Davis where he studied non-growing season carbon fluxes on the North Slope of Alaska.

Title: Updates & outlooks in measuring phytoplankton accessory pigments from hyperspectral ocean color

Presenter(s): Dr. Ali Chase, University of Washington Applied Physics Lab

Sponsor(s): NOAA Ocean Color Coordinating Group (NOCCG)

Seminar Contact(s): Veronica.Lance@NOAA.gov

Abstract: Interest in measuring phytoplankton accessory pigments from satellite platforms is motivated by a need to understand distributions of phytoplankton communities, and their variability in space and time. Accessory pigment assemblages provide information to help move beyond estimates of total phytoplankton biomass, and towards observations of different phytoplankton communities. This talk will give an overview of two different approaches to quantifying phytoplankton pigments from hyperspectral remote-sensing reflectance, as well as demonstration of initial results of algorithm application to the hyperspectral Ocean Color Instrument (OCI) on the PACE satellite (launched in Feb 2024). Early results show promise for potential detection of different phytoplankton pigments " and thus communities " from space. The ongoing collection of in situ data to enable evaluation and improvement of pigment algorithms will also be discussed. Speaker

Bio(s): Ali is a bio-optical oceanographer at the Applied Physics Laboratory at the University of Washington, in the Air-Sea Interaction & Remote Sensing department. Ali leads the Marine Phytoplankton & Optics Group, with research interests centered on combining information from in situ optical measurements and plankton cell imagery to detect different phytoplankton types present in the water, and extending these methods to remote sensing observations to understand and explain changes in phytoplankton communities through time and space, and the subsequent consequences for marine ecosystems. Ali earned her B.A. from Bowdoin College in Maine, and her M.S. and PhD from the University of Maine in the Boss/Karp-Boss lab before moving to the University of Washington in 2020.

Presenter(s): Adrianne Akmajian, Marine Ecologist/ Marine Ecology Division Manager, Makah Fisheries Management

Sponsor(s): NOAA Office of National Marine Sanctuaries and NOAA's Olympic Coast National Marine Sanctuary

Seminar Contact(s): Claire.Fackler@noaa.gov

Abstract: Harmful algal bloom toxins are prevalent along the Pacific Coast of North America and may be detected in marine wildlife without deleterious effects on health. We measured concentrations of domoic acid and saxitoxin in fecal samples from free-swimming gray whales (Eschrichtius robustus) feeding on the northwest coast of Washington, USA in the summer and fall of 2018 and 2019. Concentrations in gray whale feces were compared to those measured in shellfish and to phytoplankton cell counts taken over the same time period. Photo-identification of individual whales allowed for insights about feeding location and exposure to toxins.Register: https://attendee.gotowebinar.com/register/8302759093071762009

Abstract: Hydrodynamic modeling for coastal flooding risk assessment is a highly relevant topic. Many operational tools available for this purpose use numerical techniques and implementation paradigms that reach their limits when confronted with modern requirements in terms of resolution and performances. In this work, we present a novel operational tool for coastal hazards predictions, currently employed by the BRGM agency (the French Geological Survey) to carry out its flooding hazard exposure studies and coastal risk prevention plans on International and French territories. The model, called UHAINA (wave in the Basque language), is based on an arbitrary high-order discontinuous Galerkin discretization of the nonlinear shallow water equations with SSP Runge"Kutta time stepping on unstructured triangular grids. It is built upon the finite element library AeroSol, which provides a modern C++ software architecture and high scalability, making it suitable for HPC applications. We will discuss development of the mathematical and numerical framework of the model, focusing on two key ingredients : (i) a pragmatic treatment of the solution in partially dry cells which guarantees efficiently well-balancedness, positivity and mass conservation at any polynomial order; (ii) an artificial viscosity method based on the physical dissipation of the system of equations providing nonlinear stability for non-smooth solutions. A set of numerical validations on academic benchmarks is performed to highlight the efficiency of these approaches. Finally, UHAINA is applied on a real operational case of study, demonstrating very satisfactory results.

Abstract: Phytoplankton are vital components of aquatic ecosystems, contributing to primary production, nutrient cycling, and serving as indicators of environmental health. This seminar presents results from a NOAA Experiential Research & Training Opportunity (NERTO) with mentor Steve Morton from NOS, NCCOS, which involved a morphological analysis of phytoplankton community composition using light and scanning electron microscopy. This work focused on identifying key taxa, including potential harmful algal bloom (HAB) species, to support NOAA's efforts in coastal monitoring and ecosystem management. Specifically, the phytoplankton diversity in Ocean Springs Harbor, Mississippi, was examined focusing on diatom and other plankton communities. By integrating traditional identification methods, this research enhances NOAA's capacity to track biodiversity shifts and environmental changes. The experience also provided valuable insight into NOAA's mission, professional networking opportunities, and hands-on training in phytoplankton analysis, which will inform future research endeavors.

Abstract: Incorporating eDNA into coastal monitoring may support management of key species, and identify the arrival of new and expanding species, as well as a variety of biodiversity metrics. However, eDNA analyses and interpretation can be challenging in some estuaries where high turbidity, organic material, and DNA transport may inhibit or confound results. Resource managers who are unfamiliar with eDNA may find results difficult to interpret and may be reluctant to use data generated by an unfamiliar, non-standardized method. We present findings and recommendations from a two-year pilot project that involved collecting quarterly eDNA samples at 10 National Estuarine Research Reserves in coordination with existing water quality sampling. Fish species lists were compared to expected species identified through other methods. General eukaryotes species data were used to identify differences between sites and estuaries, seasonal trends, and develop biodiversity metrics. Results were presented to local managers to provide information on fish assemblage and biodiversity at each location. Managers were encouraged to offer feedback on useability, accessibility and barriers to use of eDNA at each site. We found that eDNA monitoring can substantially benefit resource managers, particularly in locations with limited conventional biological monitoring, but that support for interpretation and post-analysis processing is very important for many users. We will present an overview of findings, and communications materials we have found beneficial to managers.

Meeting number (access code): 2826 895 7840

Meeting password: 2025AFSC

Abstract: Identifying Aquaculture Opportunity Areas (AOAs) in Alaska is a science and community-driven planning process to assist in the development of a sustainable seaweed and shellfish farming industry in State waters. By identifying suitable areas for multiple aquaculture operations through spatial analysis and the National Environmental Policy Act (NEPA) review process, AOAs aim to balance ecological, economic, and social considerations. For the spatial analysis, NOAA's National Center for Coastal Ocean Science employed whole-ecosystem spatial modeling methods to incorporate the best available data and public input. A key consideration in AOA siting is the Alaska Department of Fish and Game's 50-50 rule, which requires that kelp farms source spores from a minimum of 50 unrelated individual organisms within 50 km of the farm each year. This rule ensures genetic diversity by allowing many local plants to contribute to the farm's genetic makeup, ensuring that farm-released spores are genetically similar to wild stocks. To support this, a seaweed source inventory is being developed through a participatory mapping process, aiding in the AOA siting analysis.

Abstract: The trade space ofmeasurements for a future planetary boundary layer (PBL) mission is large andrapidly expanding. To design a mission that addresses broad science andapplications objectives, and remains cost-effective, we have designed an observingsystem simulation experiment (OSSE) system tailored for the PBL that has thefollowing key features:

1. Interfaces to a collection of global km-scale and regional sub-km scale nature runs that represent a large range of weather states and PBL structures.
2. A collection of passive and active instrument simulators capable of exploring trades among the diverse set of PBL measurements.
3. Orbit simulators that can represent constellations of satellites at varying altitudes and with diverse observing strategies.
4. Data fusion techniques that account for measurement uncertainty and optimally combine information from observations with very different spatial and temporal resolutions.
5. A computational framework that parallelizes radiative transfer and retrievals efficiently over diverse compute environments from individual multi-core workstations to distributed high performance computing architectures to the cloud.

OurPBL OSSE system results in 1) near-term actionable instrument-level trades fora PBL formulation effort, and 2) a longer-term and comprehensive assessment ofmeasurement combinations and constellation configurations to inform PBL missiondesign. This presentation will demonstrate the use of our OSSE system toquantify measurement information for the current program of record, theexpected measurements available during the 2030s, and several hypotheticalconstellations tailored toward PBL observations.

Seminar Contact(s): Caroline Donovan, caroline.donovan@noaa.gov

Accessibility: Closed captioning available through Google Meet platform

Abstract: Emerging technologies, like remote sensing and uncrewed aerial vehicles, are becoming more increasingly present in natural resource management for Pacific islands. This is especially significant for rural island communities in Micronesia that are vulnerable to numerous environmental threats, such as typhoons, wildfires, coral bleaching, and invasive species. UAVs or drones are a transformative solution to address data and surveying gaps concerning these threats. In Micronesia, the University of Guam (UOG) Drone Corps program was established to train individuals into becoming FAA art107b-certified remote pilots to support the work of scientists and natural resource managers. UOG Drone Corps works closely with local agencies, governmental programs, and educational institutions to deliver geospatial datasets (i.e. RGB, NDVI, LIDAR) and readily accessible imagery to guide long-term monitoring. In this presentation, we will highlight the UOG Drone Corps' research, collaboration, and outreach aimed at producing effective resources for local island communities. As an example of our products and services, we will feature our partnership with the National Oceanic and Atmospheric Administration's (NOAA) Guam Coral Reef Initiative and our current efforts to map Guam's priority coral reef sites.

Title: (Talk 1): Dynamics in phytoplankton size fractionated primary production in the East Bering Sea(Talk 2): Assessing Water Clarity in the Chesapeake Bay using Satellite-derived Secchi Disk Depth
CoastWatch Seminar Series

Presenter(s): Jonathan Sherman; Seunghyun Son

Sponsor(s): NOAA CoastWatch


Seminar Contact(s): Rebecca.Trinh@noaa.gov

Abstract: (Abstract 1): Phytoplankton net primary production (NPP) forms the base of the global marine food web, where the size structure of the phytoplankton community strongly influences trophic transfer efficiency through the food web. The East Bering Sea, a critical fishery supporting~50% of the total U.S. harvest volume, is undergoing rapid change including warming temperatures and loss of sea ice and it remains unclear how these changes impact the total and size fractionated NPP and subsequent trophic levels. Here, we present initial results from a Phytoplankton Size Class Absorption based Production Model (PSC-AbPM) which derives NPP contributions from pico-, nano-, and microphytoplankton size classes. The PSC-AbPM was applied to 20 years of ocean color data from OC-CCI over the East Bering Sea, and compared to other widely used NPP models and in situ observations. The PSC-AbPM is able to capture the seasonal succession of phytoplankton size classes, with a massive spring bloom dominated by microphytoplankton, followed by summertime low production dominated by the smaller picophytoplankton class. Additionally ,the model captures the tight seasonal relationship between the spring bloom timing and ice extent over the winter. Lastly, we show the dynamical approach used to derive each size class photosynthetic efficiency parameter throughout the year. (Abstract 2): Secchi disk depth (SDD) is a conventional in situ optical method of measuring water clarity, which is an important characteristic of water quality and ecosystem health. Assessments of SDD from remotely-sensed ocean color data benefit from wide spatial and temporal coverage but are subject to low accuracy resulting from unstable relationship between water transparency and the color of water surface. A semi-analytical SDD algorithm (here after called CB-SDD algorithm) proposed for turbid coastal waters was extensively evaluated in the Chesapeake Bay. Satellite SDD maps from MODIS-Aqua and VIIRS-SNPP generated using CB-SDD algorithm showed lower bias and higher accuracy as compared to other methods and found that SDD are shallower in the northern bay and upstream in its tributaries, while SDD are deeper along the main stem in the middle and lower parts of the bay. Expected seasonal and interannual variation in SDD in the Bay are evident in the satellite results in relation to seasonal and interannual variations river discharge patterns. Our results show that satellite data can be fit-for-purpose for water quality management across the Chesapeake Bay and this satellite method can be considered to extend water quality observations where and when in situ observations are lacking in the Bay.

Sponsor(s): NOAA NWFSC Monster Seminar Jam

Seminar Contacts: Vicky Krikelas, Vicky.Krikelas@noaa.gov

Abstract: Rapid system-wide changes that accompany regime shifts are a considerable challenge for resource management and human communities. In the Northeast Pacific, the recovery of sea otters following the 19th century fur trade is triggering an ecological regime shift with profound social implications. This talk will overview research into the patterns and processes on rocky reefs where sea otters are recovering, revealing new insights into the trophic interactions that influence the resilience of kelp forests. It will also highlight knowledge and insights from a collaborative partnership seeking to understand how coastal Indigenous communities are adapting to the changes that sea otters trigger. This work reveals the complexities, surprises, and contextual nuances that characterize sea otter recovery in tightly coupled human-ocean systems, and offers the foundations for a road map to improve future human-otter coexistence.

Presenter(s): Amy Van Cise, University of Washington School of Aquatic and Fishery SciencesSeminar Contacts: Rachel Wuest (Rachel.Wuest@noaa.gov), Amanda Warlick (Amanda.Warlick@noaa.gov)

Accessibility: Accessibility information: closed captioning

Abstract: By way of introduction to the AFSC team of scientists, this seminar first introduces the research efforts of UW's Whale and Dolphin Ecology lab, followed by a description of some programs of interest at UW that may support collaboration between the two organizations. Research at the Whale and Dolphin Ecology lab is primarily focused on studying marine mammal evolutionary ecology using a suite of omics and acoustics approaches. Much of our research is focused on sociality - the suite of socially learned behaviors specific to a group of animals "as an integral ecological strategy that drives evolutionary processes. This research has included genetic and genomic sequencing to understand population structure and historical demographics or evolutionary processes, genetic metabarcoding to study diet or microbiomes, and eDNA to improve our understanding of 3D spatial distributions and population structure in elusive species. The lab is also involved in several acoustics endeavors, including studying the vocal behavior of Cook Inlet beluga whales and monitoring delphinid interactions with seaweed farms off the coast of Puerto Rico. More broadly, I will outline how we may use UW's internship programs, marine mammal ecology course, and the UW SAFS graduate research program as potential avenues for collaboration between AFSC and the UW Whale and Dolphin Ecology lab in the areas of research, outreach, or education.

Title: The NOAA Research Global-Nest Initiative: New Frontiers in Numerical Modeling

Presenter(s): Dr. Lucas Harris, NOAA Geophysical Fluid Dynamics LaboratorySeminar Contacts: Morina Royer (morina.royer@noaa.gov), John Xun Yang (jxyang@umd.edu). Host: Earth System Science Interdisciplinary Center (ESSIC)

Abstract: Traditional global models and high-resolution limited-area models are limited in the range of phenomena they can represent with the fidelity needed by both science and society. This partitioning also restricts two-way interactions between large-scale circulations and local phenomena, especially for small-scale convective and orographic processes that feed back onto larger scales. The NOAA Research Global-Nest Initiative is a multi-center effort to develop new global-nested and global storm resolving models to address these shortcomings of traditional models and to bring together both weather prediction and climate simulation models. This effort centers around the GFDL System for High-resolution prediction on Earth-to-Local Domains (SHiELD), built upon a strong foundation of common technologies, including the FV3 Dynamical Core, seamlessly integrated with both the UFS and the GFDL Seamless Modeling Suite. I will describe already the successes of the initiative, including the new 6.5-km SHiELD used for real-time weather prediction, new versions of our T-SHiELD and C-SHiELD global-nest models, and our X-SHiELD global-storm resolving model. Both scientific and prediction advances have been demonstrated, especially regarding significant advances in tropical cyclone track prediction skill and in cross-scale interactions for tropical convection and mountain snowpack, amongst others. I will close with discussion of new technologies, including this efforts' contributions to machine learning models through the Allen Institute for Artificial Intelligence, and to Pace, a complete rewrite of FV3 and SHiELD in Python for performance-portable computing, especially GPUs.Subscribe/Unsubscribe to the NOAA Science Seminar Series weekly email:Send an e-mail to OneNOAAscienceseminars-request@list.woc.noaa.gov with the word 'subscribe' or 'unsubscribe' in the subject or body of the email.

Title: Who Eats Who and Why

Presenter(s): Amy Cook Ph.D. Professor, The Evergreen State College

Sponsor(s): NOAA NWFSC Monster Seminar Jam

Seminar Contacts: Vicky Krikelas, Vicky.Krikelas@noaa.gov

Abstract: In several ways, sculpins are a model organism for studying feeding behavior. Drawing from my work on marine species of sculpins on the West Coast, this presentation will provide an overview of what influences the composition of a fish's diet and discuss particular examples and some of the challenges in studying feeding behavior. The prey species that end up in the diet of a fish are the result of a sequence of factors including availability in the environment, encounter, detection, decision to attack and prey capture performance. Each of these factors is, in turn, influenced by the morphology and behavior of the fish. A juvenile tidepool sculpin (Oligocottus maculosus) foraging for food encounters a particular set of potential prey that is linked to the prey species present in the environment and how the fish is searching " cruising, sit-and-wait or saltatory foraging. In order for a prey to be attacked, it must be detected by the fish. Many predators do not attack every potential prey they encounter so there is an element of selectivity in the feeding sequence. Lastly, among the prey that a predator attacks, some are easier to capture than others. If we shift are perspective and look at this sequence from the perspective of prey, we see that many anti-predator strategies shown by prey species have evolved to challenge the predator at one or more of these stages in the feeding event. For example, camouflage makes a prey more difficult to detect and highly elusive prey, with high levels of vigilance and strong locomotor abilities, are more difficult to capture. This sort of holistic view of fish feeding gives us a more detailed view of ecology, behavior and the evolutionary history of predators and prey.

Title: GLONET: Mercator's End-to-End Neural Forecasting System

Presenter(s): Anass El Aouni (Mercator Ocean International, Toulouse, France)

Sponsor(s): NOAA Coastal Ocean Modeling Seminars: https://coastaloceanmodels.noaa.gov/seminar/

SeminarContact: Alexander.Kurapov@noaa.gov

Abstract: Accurate ocean forecasting is crucial in different areas ranging from science to decision making. Recent advancements in data-driven models have shown significant promise, particularly in weather forecasting community, but yet no data-driven approaches have matched the accuracy and the scalability of traditional global ocean forecasting systems that rely on physics-driven numerical models and can be very computationally expensive, depending on their spatial resolution or complexity. Here, we introduce GLONET, a global ocean neural network-based forecasting system, developed by Mercator Ocean International. GLONET is trained on the global Mercator Ocean physical reanalysis GLORYS12 to integrate physics-based principles through neural operators and networks, which dynamically capture local-global interactions within a unified, scalable framework, ensuring high small-scale accuracy and efficient dynamics. GLONET's performance is assessed and benchmarked against two other forecasting systems: the global Mercator Ocean analysis and forecasting 1/12 high-resolution physical system GLO12 and a recent neural-based system also trained from GLORYS12. A series of comprehensive validation metrics is proposed, specifically tailored for neural network-based ocean forecasting systems, which extend beyond traditional point-wise error assessments that can introduce bias towards neural networks optimized primarily to minimize such metrics. The preliminary evaluation of GLONET shows promising results, for temperature, sea surface height, salinity and ocean currents. GLONET's experimental daily forecast are accessible through the European Digital Twin Ocean platform EDITO.

Title: [C]worthy: Navigating to Solutions for Ocean-Based Carbon Dioxide Removal

Presenter(s): Matthew Long

Sponsor(s): NOAA Global Monitoring Laboratory (https://gml.noaa.gov/about/seminars.php)

Seminar Contacts: Monica Madronich (monica.madronich@noaa.gov)Abstract : There is scientific consensus that carbon dioxide removal (CDR) will be necessary to meet the Paris Agreement's goal of keeping the rise in global temperature to within 2C. Among the most promising and scalable approaches to CDR are ocean-based pathways. These methods capitalize on natural physical and biogeochemical processes " but the ocean is vast, dynamic, and ecologically complex, presenting significant challenges to quantifying the amount of carbon removed through CDR interventions. Indeed, a key bottleneck to scaling ocean-based CDR is the absence of robust Monitoring, Reporting, and Verification (MRV) systems " a gap in capacity that limits investment and hampers growth of an ocean-based carbon removal industry. In this talk, we'll introduce [C]Worthy, a new non-profit research organization dedicated to developing scientifically credible approaches to MRV for ocean-based CDR. Critically, while direct observations provide valuable insights, they are insufficient to assess the effectiveness of ocean-based CDR interventions; advanced oceanographic and biogeochemical modeling tools are a requirement. We'll explore how [C]Worthy is accelerating the development of a standardized, open-source modeling system for quantifying ocean-based CDR, aiming to enable this industry to scale on the basis of credible science and contribute effectively to mitigating carbon dioxide increases in the atmosphere.

Bio(s): Matthew Long, PhD, is co-founder and CEO of [C]Worthy, a non-profit research organization focused on building tools to ensure safe, effective ocean-based carbon dioxide removal (CDR). As a scientist at the National Center for Atmospheric Research, Long contributed to the Community Earth System Model and conducted research on ocean biogeochemistry, marine ecosystems, and the global carbon cycle. Prior to NCAR, he built and deployed instruments to measure ocean carbon variables, worked as a civil engineer developing river and sewer-network models, and taught high school as a United States Peace Corps volunteer in Tanzania. Dr. Long holds Master's and Bachelor's degrees in Civil and Environmental Engineering from Tufts University and a Ph.D. in Oceanography from Stanford University.

Title: Sea Otters in Washington State: Lessons Learned from the "Grand Experiment" of the Maritime Fur Trade
National Marine Sanctuaries Webinar Series

Presenter(s): Jessie Hale, PhD, Postdoctoral Fellow with the National Marine Sanctuary Foundation, in support of NOAA Fisheries

Sponsor(s): NOAA Office of National Marine Sanctuaries and NOAA's Olympic Coast National Marine Sanctuary

Seminar Contact(s): Claire.Fackler@noaa.gov

Accessibility: Captioning will be provided for the recording.

Abstract: Sea otters historically occurred off the outer coast of Washington State until 1911 when the last sea otter was reported to have been shot. Sea otters were absent from Washington State until 1969 and 1970, when 59 sea otters were translocated from Alaska. This grand experiment of the maritime fur trade throughout the North Pacific, including in Washington, has provided researchers with a unique opportunity to study sea otter populations by comparing areas where otters are absent versus areas in varying stages of recovery. While the maritime fur trade undeniably devastated sea otter populations, it is unlikely that we would know as much about sea otter ecology and biology if it had not occurred. Through long-term study, we have witnessed the recovery of remnant and reintroduced sea otter populations in a variety of habitat types and geographies. The unique ability to study sea otter population recovery in this array of contexts has allowed for synthesis of data from many studies and regions, leading to a more comprehensive understanding of consistencies and differences across sea otter populations, and ultimately the drivers of sea otter population dynamics. Dr. Jessie Hale will describe the history of sea otters in Washington State, including the translocation of sea otters back to Washington, and what we have learned since then about their population dynamics, foraging ecology, spatial ecology, and more.

Remote Access: https://uaf-accap.org/event/ocean-acidification-webinar/

Abstract: Ocean acidification is a growing topic of interest and concern for Alaska communities. Alaska has been identified as a hotspot, and the effects of ocean acidification are likely to have serious implications for fisheries, food security and the economy. Researchers with the University of Alaska Fairbanks and the National Oceanic and Atmospheric Administration (NOAA) are monitoring ocean acidification in coastal waters around Alaska, and are also exploring ecological and socio-economic impacts. In recent years, Tribes, coastal communities and industry groups have joined the monitoring effort. The Alaska Ocean Acidification Network brings together these diverse entities and more to share and expand the understanding of ocean acidification processes and consequences, as well as explore potential adaptation and mitigation strategies. These conversations include what is the data telling us and how can it help to inform local community decisions? This presentation will include a refresher on ocean acidification, the primary information needs voiced by Alaskans, and what we've learned from recent research and monitoring about conditions and species response.

Bio(s): Darcy Dugan led the development and launch of the Alaska OA Network in 2016, and is now the network's director. She has worked for the Alaska Ocean Observing System since 2009, collaborating with scientists, Tribes, coastal community members and others to identify and fill gaps in ocean monitoring and bring relevant ocean information to Alaskans. Natalie Monacci is a chemical oceanographer and the director of the Ocean Acidification Research Center at the University of Alaska Fairbanks. She monitors the intensity, duration, and extent of ocean acidification in Alaska's waters using various methods and partnering with many groups around the state.

Title: Discrete variance decay analysis of spurious mixing

Presenter(s): Sergey Danilov (AWI, Bremerhaven, Germany)

Sponsor(s): NOAACoastal Ocean Modeling Seminars: https://coastaloceanmodels.noaa.gov/seminar/

SeminarContact: Alexander.Kurapov@noaa.gov

Abstract: We examine the use of discrete variance decay of tracers to estimate the numerical mixing a tracer transport step. Expressions for local discrete variance decay (DVD) rates are directly derived from discrete tracer equations without any assumptions on the discrete fluxes of the second moment of the tracer. They relate the DVD rates to the fluxes of the first moment through the faces of scalar control cell. Mixing associated with advective and diffusive fluxes is thus estimated. For third- or higher-order advection schemes, the DVD rates are contaminated by dispersive errors intrinsic to the approach, introducing uncertainty to the locality of any estimates produced by it. Additional temporal averaging or coarse-graining is thus necessary. Through the application of this technique to a test case of a baroclinically unstable flow, numerical mixing is found to be correlated with the distribution of eddy kinetic energy. Numerical mixing induced by vertical advection is found to be relatively small and correlated with the distribution of buoyancy fluxes. The explored high-order schemes are found to demonstrate levels of spurious mixing which may locally exceed physical mixing.Slides, Recordings, OtherMaterials: TBDSubscribe to the NOAA ScienceSeminar Series weekly email: Sendan e-mail to OneNOAAscienceseminars-request@list.woc.noaa.gov with the word 'subscribe' in the subject or body.Visit the NOAA Science Seminar Series website for more information.

Abstract: The critically endangered eastern North Pacific right whale (NPRW; Eubalaena japonica) is currently one ofthe rarest whale populations (n < 50), having been severely depleted byhistoric legal and illegal whaling. Despite their precarious status, little isknown about their contemporary distribution and seasonal movements. During thisseminar, I will present findings from over a decade of passive acoustic recordingsfrom historical NPRW feeding areas, specifically the eastern Bering shelf,Aleutian Islands, and northern Gulf of Alaska. These passive acoustic data camefrom an existing network of long-term passive acoustic recorders maintained byAFSC's Marine Mammal Laboratory. Right whale detections reveal strongseasonality consistent withcontemporary feeding grounds, with spatial and temporal variability linked tooceanographic and prey features. These findings provide new insightsinto their contemporary habitat use, which could inform ongoing revisions tocritical habitat designations among changing ocean conditions.

Abstract: The ecological importance of sharks is a pervasive assertion often used to advocate for their conservation. Statements like "sharks are essential to healthy marine ecosystems" have become widely accepted dogma. However, the underlying mechanisms and empirical evidence supporting these claims are not poorly understood. The goals of this presentation are to: (1) review the ecological theories underpinning top-down regulation through which apex predators like sharks might influence marine ecosystems, (2) share key findings from collaborative research on predator-prey dynamics, providing insights into the empirical evidence for these mechanisms, and (3) outline considerations for future research aimed at uncovering the potential ecosystem-level effects of shark declines and recoveries.

Title: Cryptic Species Identification

Part of the NOAA Omics Seminar Series

Presenter(s): Anita Wray, Genetic Data Analyst, Pacific States Marine Fisheries Commission

Sponsor(s): NOAA Omics

Seminar Contact(s): Nicole Miller, NOAA 'Omics Portfolio Specialist, noaa.omics@noaa.gov

Remote Access: Register Here

Abstract: In the case of Pacific rockfishes (genus Sebastes), accurate species identification has been complicated by cryptic species pairs that are indistinguishable in the field, especially among recreational anglers. This issue is critically important for the vermilion/sunset rockfish complex, as it is California's 3rd most commonly landed recreational species. Discontinuities in depth, spatial distribution, and larval settlement, along with subtle differences in coloration in vermilion rockfish, prompted genetic research that revealed evidence for reproductive isolation and speciation. However, little is known about how the biology, distribution, abundance, catch history, and other aspects of the newly described sunset rockfish may differ from those of true vermilion rockfish. As such, there is a gap in the data needed to evaluate whether these species should be assessed independently or as a complex. This research aims to examine the distribution and key biological characteristics of vermilion and sunset rockfish in southern California to provide data to assist the stock assessment process and support appropriate management measures for both species. Using specimens captured during collaborative research surveys with the sportfishing and commercial sectors, we identified and assigned individuals to species using a custom GT-seq panel. We compared the specific spatial and depth distributions of over 25,000 combined samples of vermilion and sunset rockfish. In addition, biological parameters, including length-weight relationships, growth rates, maximum ages, and the presence of sexual dimorphism for all of these parameters, were analyzed. Findings are examined in the context of existing information about the species pair.

Bio(s): Anita is a Genetic Data Analyst working concurrently with the Genetics and Evolution Program and the Fishery Resource Analysis and Monitoring Divisions at the NOAA NWFSC. She leads research on many rockfish species, including species identification, epigenetic aging, and database management. She received her MS from the University of Washington, where she assessed the population structure and interspecific hybridization of eight rockfish species in Puget Sound, WA.

Abstract: NOAA's National Centers for Coastal Ocean Science (NCCOS) has been an active partner in NOAA's Integrated Ecosystem Assessment (IEA) Program since the Program's inception, with the overarching goal of enabling Ecosystem-Based Management (EBM) in coastal marine waters of the US. In the Northeast Region, NCCOS has developed a suite of physical, ecological, and socio-economic indicators, to explore the ecological context of Stellwagen Bank National Marine Sanctuary (SBNMS) within the larger Gulf of Maine ecosystem.
The Sanctuary, in marine waters offshore of Massachusetts, represents a small but significant portion of the Northeast IEA's Gulf of Maine study area. Because of the strong linkages in oceanographic and biological dynamics between Stellwagen Bank and the larger Gulf of Maine ecosystem, the results of the Northeast IEA are highly relevant to questions of interest for the Sanctuary.
Results include:
Time series of oceanographic parameters, including HABs (Alexandrium).
Derivation of benthic landforms using GIS tools.
Analysis of cetacean distribution from recent models.
Analysis of recent seabird distribution models produced by NCCOS.
Time series of Sanctuary program sand lance monitoring.
Together, these results are helping to inform resource management at both the local and regional scale.

Title: Numerical mixing suppresses submesoscale baroclinic instabilities over sloping bathymetry

Abstract: Numerical mixing, the spurious mixing generated by the discretization of tracer advection, is a ubiquitous feature of numerical ocean models. I will present results from a recent JAMES paper that examined numerical mixing in submesoscale eddy-resolving ROMS simulations of the Mississippi River Plume. We found that numerical mixing dominated physical mixing"the destruction of salinity variance prescribed by closure parameterizations"in frontal zones and within the mixed layer. We studied the impacts of numerical mixing on the larger-scale flow by comparing three tracer advection schemes (MPDATA, U3HC4, and HSIMT) in simulations with no prescribed horizontal mixing. We evaluated the dynamics of submesoscale instabilities using volume-integrated eddy kinetic energy (EKE) and available potential energy (APE). While the MPDATA and U3HC4 simulations has similar EKE and APE, the HSIMT simulations had over twice the numerical mixing, 25% less EKE, and reduced isohaline variability, evidence that numerical mixing suppressed submesoscale dynamics. We also performed experiments with variable horizontal viscosity and diffusivity coefficients to show that small amounts of prescribed horizontal mixing reduce numerical mixing and marginally increase EKE. A key finding is that numerical mixing generally impacts the flow differently than prescribed horizontal mixing, which we think is due to the anti-diffusive impacts of negative numerical mixing at the grid scale. I hope to discuss if and how we can reduce the unwanted impacts of numerical mixing in primitive equation models so that it behaves similarly to implicit LES models, where implicit dissipation is used as a substitute for subgrid-scale models.

Title: Near Real Time Ultra High Resolutions ASCAT Wind Vector and Ice Products in US Coastal Zones
CoastWatch Seminar Series

Presenter(s): Seubson (Golf) Soisuvarn - NOAA STAR Ocean Surface Winds Team, UCAR

Sponsor(s): NOAA CoastWatch


Seminar Contact(s): Rebecca.Trinh@noaa.gov

Remote Access:

Abstract: The Advanced SCATterometer (ASCAT) is a vertically polarized C-band ocean wind radar sensor carried on the Metop series of three polar-orbiting satellites launched between October 2006 and November 2018. The NOAA produces two global ocean wind products with the resolution of 12.5 km and 25.0 km up to 15 km of the coast for its operational users. While the ASCATs provide invaluable data in the open ocean, due to land contamination of the signal, most inner coastal zones are left void of the data. Most coastal marine activity occurs within a few kilometers of the coast, coastal observations are also needed for ocean forcing for upwelling affected areas. In order to retrieve winds closer to the coast, a coastal wind retrieval algorithm that utilizes enhancement resolution technique and the land contamination removal was developed and applied to the ASCAT measurements. This allowed us to retrieve winds within 20 km inner coastal zone. The enhanced resolution can be achieved by utilizing overlapping measurements of the ASCAT antenna gain. For each near coastal measurement amount of the land signal contamination is determined by computing land contamination ratio (LCR). The normalized radar cross section (NRCS) measurements over near by land mass are used to calculate a mean and a standard deviation of the land brightness for each coastal observation. By using the LCR and the mean and the standard deviation of the land brightness we have developed the land contamination correction for each coastal NRCS slice is determined within a few iterations. However in the vicinity of strong land brightness, the proposed NRCS corrections alone cannot completely remove land contamination. A post wind retrieval processing is developed and applied before final coastal wind product is produced. This post wind retrieval processing involves processing of the corrected NRCS using varying LCR threshold. First Pilot coastal wind and ice ASCAT product in US coastal regions is being produced in NRT for operational validation. New product will be presented and discussed.

Bio(s): Seubson Golf Soisuvarn joined the NOAA/NESDIS OceanSurface Winds Science Team in 2006 as a UCAR visiting scientist and iscurrently a UCAR Project Scientist. His research focuses on the development ofactive and passive microwave remote sensing techniques for the ocean surface,with an emphasis on retrieving ocean surface wind fields. His work includes improvingwind retrieval algorithms and developing new products. Seubson has a backgroundin electrical engineering, earning a B.Eng. from Kasetsart University inBangkok, Thailand, in 1998.

Title: Informing Pacific cod sensitivity to environmental stressors through physiology

Presenter(s): Emily Slesinger, Research Fish Biologist, Alaska Fisheries Science Center

Sponsor(s): NOAA NMFS SWFSC Fisheries Ecology DivisionSeminar contact: tanya.rogers@noaa.gov.

Remote Access: https://noaanmfs-meets.webex.com/noaanmfs-meets/j.php?MTID=me1828d5bdbdc592e989ccb429e285e32; Password: fedsem1nar! ; Join by phone: 415-527-5035 (US only, not a toll-free number). Access code/meeting number: 2828 966 2761

Abstract: Pacific cod (Gadus macrocephalus) are distributed throughout the Eastern Bering Sea and Gulf of Alaska, and support the second largest commercial groundfish fishery in Alaska. At the southern extent of their range, a series of marine heatwaves in the Gulf of Alaska led to recruitment failure and closure of the Gulf of Alaska fishery in 2020. At the northern extent of their range, Pacific cod may be migrating farther north into the Northern Bering Sea as ocean temperature warms and sea ice extent decreases. Throughout their range, ocean acidification has also been occurring, seen through decreases in ocean pH and increases in water CO2 concentration. With rapid changes occurring in Pacific cod habitat, it is imperative to understand their thermal sensitivity, at both the cold and warm extremes, as well as the potential for ocean acidification to interact with thermal responses. In this seminar, I will present some of our laboratory research on Pacific cod responses to ocean warming and ocean acidification across multiple life stages, where we utilized several physiological approaches including metabolic responses, enzyme activities, swimming capacity, and gene expression. We will also discuss the usefulness of physiological metrics in fisheries science, through the development of biological indicators and parameterization of distribution models and stock assessments with mechanistic data from the laboratory.

Bio(s): Dr. Emily Slesinger is a Research Fish Biologist in NOAA's Alaska Fisheries Science Center in Newport, OR.

Title: An Analysis of Surface Waves in the Caribbean Sea based on a High-Resolution Numerical Wave Model

Presenter(s): Brandon Bethel (Small Island Sustainability, University of The Bahamas)

Sponsor(s): NOAA Coastal Ocean Modeling Seminars: https://coastaloceanmodels.noaa.gov/seminar/

Seminar Contact(s): Alexander.Kurapov@noaa.gov

Abstract: Surface waves are extremely important in a large variety of oceanographic applications and thus, the study of their spatiotemporal characteristics remains crucial. This study analyzes waves in the Caribbean Sea (CS) and western Atlantic Ocean (AO) using a high-resolution (HR) Simulating WAves Nearshore model validated with buoy observations and paired with a HR bathymetric dataset from 2010 " 2019. Island sheltering effects are examined but special attention is given to these effects under Hurricane Dorian in The Bahamas using observations from the China-France Oceanographic Satellite. Results illustrate that wave heights within the CS fluctuated with Caribbean Low-Level Jet activity, but a different wave regime exists within the AO. While wind waves overwhelmingly dominate the wave field and this is true even in the AO, surprisingly, the contribution of swell in the central CS was equal to one site in the AO. Possibly, due to interaction with the shallow Nicaraguan Rise, wave heights were strongly (depth-induced) refracted nearly 45, a feature unseen in previous research using coarse bathymetric datasets. Island sheltering effects were pervasive and were naturally most pronounced under hurricane conditions. Crucially, New Providence in The Bahamas is vulnerable to hurricane-forced waves funneled through the Grand Bahama and Northeastern Providence Channels.

Title: In Search of a Resilience Index: Comparing Indicators of Resilience for Coastal Communities

Presenter(s): Amy Freitag, Ph.D., Sociologist. NOAA/NOS National Centers for Coastal Ocean Science (NCCOS), Marine Spatial Ecology Division, Biogeography Branch, Oxford Cooperative Lab, Oxford MD; and Ramesh Paudyal, Consolidated Safety Services (CSS), under contract to NOAA/NOS NCCOS, Gainesville, FL.

Sponsor(s): NOAA's National Ocean Service (NOS) Science Seminar Series

Seminar Contacts: Moe Nelson, david.moe.nelson@noaa.gov

Location: Webinar

Accessibility: Closed Captioning will be available to viewers in Adobe Connect during the seminar.

Abstract: How do you quantify resilience in a coastal community context? This project describes a statistical journey to answer that question. The goals of this study were to: 1) identify a quantitative approach to measuring resilience in coastal communities, 2) analyze patterns of resilience, and 3) understand how patterns of resilience relate to investments in restoration and disaster recovery. We replicated and compared existing resilience indices, focusing largely on BRIC and CRSI. These indices did not show the same patterns of resilience across coastal counties of the US, though both BRIC and CRSI were useful in attempting to understand patterns of investment. This comparison and use of existing resilience indices are a first, relatively simple, step in our study of resilience before delving into more in-depth methodologies that require investment from community members.

Slides, Recordings, Other Materials: The webinar will be recorded, and the video will be viewable in Adobe Connect.

Title: Microplastics Pollution from Watersheds to Coastal Marine Systems in Southern California



Presenter(s): Andrew Gray, Associate Professor, Department of Environmental Sciences, University of California, Riverside

Sponsor(s): NOAA's National Ocean Service (NOS) Science Seminar Series, and NOAA's Marine Debris Program.

Seminar Contacts: Moe Nelson, david.moe.nelson@noaa.gov; Amy Urhin, amy.uhrin@noaa.gov

Location: Webinar

Accessibility: Closed Captioning will be available to viewers in Adobe Connect during the seminar.

Abstract: Rivers draining urbanized watersheds are known to contain high concentrations of microplastics and act as the major conveyors of microplastic pollution to the ocean. This has engendered an increased focus on microplastic sources, and transport in riverine systems, and the role of coastal hydrodynamics in determining the distribution and fate of microplastic. But how should we design microplastic monitoring plans for rivers, estuaries, and coastal marine environments if our goal is to quantify concentration, character, and flux from rivers and inform marine transport models? Here I present and discuss the results of microplastics sampling campaigns conducted on several riverine systems draining coastal watersheds in Southern California, as well as estuarine and marine shelf waters and sediment deposits. Key topics across all systems include consideration of microplastic distribution across the water column and sampler performance, as well as the effective fluvial discharge of microplastics with respect to hydrologic regimes, estuarine trapping, and the coherence of fluvial and marine conditions.

Bio(s): Dr. Andrew Gray is an Associate Professor of Watershed Hydrology in the Department of Environmental Sciences at the University of California, Riverside. Dr. Gray's research focuses on the processes controlling water and sediment transfer, with particular interest in wildfire impacts on sediment dynamics, coastal sedimentology, sediment source investigation, and microplastics pollution. The work presented in this seminar was funded by the NOAA Marine Debris Research Program and the California State Water Resources Control Board.

Title: The state-space mass balance model Ecostate, as example of adding bottom-up interactions in stock assessment

Presenter(s): James T Thorson, NMFS, AFSC, and Statistical ecologist

Sponsor(s): NOAA's National Marine Fisheries Service (NMFS) and NOAA LibrarySeminar Contacts: Dr. Bai Li (bai.li@noaa.gov) and Library Seminars

Abstract: Changes in fish growth has outsized impact on population dynamics and management. I introduce how to add bottom-up interactions to assessment models by linking individual growth to consumption rates using EcoState (a new state-space mass balance model) as example. I first review a biomass-dynamics case-study linking Bering Sea pollock productivity to krill biomass. I then review a case study involving age-structured dynamics for pollock and sablefish in the Gulf of Alaska, which shows that pollock size-at-age is informed using field surveys for copepods and krill.

Accessibility: TBA

Abstract: For millennia, Pacific salmon have been integral to the health of coastal ecosystems and human communities from California to Alaska. Salmon are ecological and cultural keystone species, connecting marine and freshwater food webs and supporting thriving fisheries. Yet, wild salmon have declined precipitously due to a combination of factors including dams, overharvest, hatcheries, and climate change. Efforts to recover salmon populations have struggled to reverse these trends.In this engaging Kraw Lecture, Eric Palkovacs will describe the development of transformative approaches to recover wild salmon populations by connecting novel insights from genes to ecosystems. Learn how this integrative research program spanning the fields of genomics, physiology, behavior, and ecology can provide insights to transform the future of Pacific salmon and the ecosystems and fisheries they support.

Bio(s): Eric Palkovacs is a Professor of Ecology and Evolutionary Biology, Associate Vice Chancellor for Research, and Director of the Fisheries Collaborative Program, which supports research, education, and outreach collaborations between UCSC and the NOAA Southwest Fisheries Science Center. His research program explores connections between evolutionary and ecological processes in freshwater and coastal ecosystems, with the goal of informing biodiversity conservation and sustainable fisheries management.

Title: Dependence of dense filament frontogenesis in a hydrostatic model

Presenter(s): Yalin Fan (Naval Research Laboratory, MS, USA)

Sponsor(s): NOAA Coastal Ocean Modeling Seminars: https://coastaloceanmodels.noaa.gov/seminar/

Seminar Contact(s): Alexander.Kurapov@noaa.gov

Abstract: In this study, a hydrostatic model - the Navy Coastal Ocean Model (NCOM) is used to analyze the temporal evolution of a cold filament under moderate wind (along / cross filament) and surface cooling forcing conditions. The experimental framework adhered to the setup used in large eddy simulations by Sulllivan and McWilliams (2018). For each forcing scenario, the impact of horizontal resolutions is systematically explored through varies model resolutions of 100 m, 50 m, and 20 m; and the influence of horizontal mixing is investigated by adjusting the Smagorinsky constant within the Smagorinsky horizontal mixing scheme. The role of surface gravity waves is also assessed by conducting experiments both with and without surface wave forcing. The outcomes of our study revealed that while the hydrostatic model is able to predict the correct characteristics/physical appearance of filament frontogenesis, it fails to capture the precise dynamics of the phenomenon. Horizontal mixing parameterization in the model was found to have marginal effect on frontogenesis, and the frontal arrest is controlled by the model's subgrid-scale artificial regularization procedure instead of horizontal shear instability. Consequently, higher resolution is corresponding to stronger frontogenesis in the model. Thus, whether the hydrostatic model can produce realistic magnitude of frontogenesis is purely dependent on the characteristic of the front/filament simulated and model resolution. Moreover, examination of the parameterized effect of surface gravity wave forcing through vertical mixing unveiled a limited impact on frontogenesis, suggesting that the parameterization falls short in representing the real physics of wave-front interaction.Slides, Recordings, OtherMaterials: https://www.google.com/url?q=https://www.sciencedirect.com/science/article/pii/S1463500324001161?via%253Dihub&sa=D&source=calendar&ust=1736868607517057&usg=AOvVaw07KEKhPcGjOw0ijIK4QZBy

Title: Evidence of impact, and the impact of evidence: Evaluating knowledge sources of ecological changes caused by European green crabs in Washington State

Presenter(s): Emily Grason, Crab team program manager, Washington Sea Grant

Sponsor(s): NOAA NWFSC Monster Seminar Jam

Seminar Contacts: Vicky Krikelas, Vicky.Krikelas@noaa.gov

Abstract: Ecological impacts of biological invasions are inherently difficult to predict given they occur at the intersection of evolutionarily novel species interactions and context dependent community properties and dynamics. In many cases, it takes years after arrival and establishment of a new species for impacts to become detectable or measurable. In some cases, this is because the invader just is not yet abundant enough to result in detectable habitat, population, or community changes. Nevertheless, a mechanistic understanding of how invasives can drive ecological or physical change in new habitats is needed to design effective management strategies - the earlier the better. While confident (and accurate) quantitative predictions of impacts may ultimately be difficult to achieve, advancing the timeline of achieving a mechanistic understanding is a useful area of research for any new invasion.

Though first detected in Washington in 1998, European green crab has only recently (3-5 years) experienced the population growth that indicates a shift to establishment. As a generalist predator, the range of impacts green crab could have through direct interactions is quite large, let alone additional indirect interactions and habitat modifications that have been observed in other parts of its invasive range. Here we organize research to date that provides evidence for locally relevant impacts of green crab. When manipulative field experiments are not feasible, as is often the case at the early stages of invasion, other types of evidence can be used to develop a robust understanding of impact contexts, geographies, and mechanisms. This framework also provides a structure to identify research gaps and needs for management.

Bio(s): Emily Grason is a marine ecologist at Washington Sea Grant. As the lead for Crab Team, she oversees a comprehensive program focused on monitoring and control of the European green crab. Starting with a flagship citizen science early detection monitoring network ten years ago, the program has expanded to support Washington's technical needs related to green crab management, including research and capacity building. She also facilitates the Oyster Drill Working Group and serves in the science seat on the Northwest Straits Commission.

Emily holds a Ph.D. in Biology from the University of Washington, completed her master's work at Western Washington University, and her undergraduate work at Bowdoin College. She really enjoys walking in, on, and through Washington's muddy, salty places, and sometimes remembers to look up for birds.
