Abstract: The Joint Polar Satellite System (JPSS) constellation currently has three polar-orbiting satellites (SNPP, NOAA-20, and NOAA-21) that orbit the globe and produce near-real-time imagery and data for National Weather Service (NWS) forecasters to employ in the operational environment. This presentation will focus on the recent in-person and virtual visits to Weather Forecast Offices (WFOs) that the JPSS Satellite Liaison (along with additional CIRA and NOAA personnel) conducted within the past year and half. The visits included interactions with NWS forecasters, the collection of forecaster feedback on the usage of satellite data in operations and discussions about the challenges that forecasters encounter within their respective County Warning Areas (CWA). Additionally, updates will be provided on the latest JPSS training materials that forecasters can access online to learn more about the utility of the datasets and applications. Near-real-time JPSS data webpages will also be highlighted to show forecasters how to access the operational and experimental JPSS products online and in the Advanced Weather Interactive Processing System " II (AWIPS-II).

Abstract: The Loop Current (LC) and its eddy-shedding dynamics profoundly impact tropical cyclone intensification, offshore platform safety, and marine ecosystems in the Gulf of Mexico. While prior studies consistently document a higher eddy-shedding probability in the summer and minimal occurrence in December, the mechanisms driving this seasonality remain poorly understood. Using 30 years of altimetry data and a 22-year reanalysis, we show that three interconnected processes govern this pattern: the Yucatan Current's (YC) seasonal cycle, its interaction with the Yucatan Peninsula, and negative eddy wind work in winter. In summer, elevated YC mean kinetic energy drives increased eddy kinetic energy and cyclonic vorticity, promoting Loop Current Frontal Eddies (LCFEs) formation and intensification. Analysis of all shedding events in the reanalysis highlights the function of LCFEs in the separation process, wherein the formation of vorticity transport barriers is critical for preventing LC-eddy reattachment and ensuring permanence. December shedding is rare because a winter YC mean kinetic energy minimum suppresses LCFE formation, while intense negative eddy wind work damps existing LCFEs in critical LC-LCFE interaction regions. Our nonlinear dynamics analysis reveals that permanent separations require a positive vorticity barrier, generated by the YC-peninsula interaction, that dynamically isolates the LC from the newly formed eddy. These barriers form following summer increases in relative vorticity production, demonstrating a direct causal link between the YC's seasonal cycle and LC eddy-shedding dynamics. We show that the fundamental physical processes governing eddy separation are present year-round, and that the seasonality emerges directly from the seasonal modulation of their intensity. This work advances our understanding of western boundary current dynamics and provides a foundation for seasonal prediction of LC eddy separation events.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.

Title: Will the Atlantic overturning circulation collapse? Insights from climate models

Presenter(s): Dr. Jonathan Baker (UK Met Office)

Sponsor(s): NOAA/Atlantic Oceanographic & Meteorological Laboratories (AOML)

Abstract: The Atlantic Meridional Overturning Circulation (AMOC) is a key part of Earth's climate system, moving heat northward across the Atlantic and influencing sea level, precipitation, and global weather patterns. While climate models agree that the AMOC will weaken under rising greenhouse gas emissions, they diverge on the extent"and whether a collapse could occur this century remains uncertain. This talk presents results from 34 CMIP6 climate models, focusing on the upwelling pathways that return AMOC deep waters to the surface. We identify a particularly sensitive branch that upwells in the Indo-Pacific and returns to the Atlantic without upwelling in the Southern Ocean. Its present-day strength strongly constrains projected weakening, yet remains poorly constrained by observations. Persistent wind-driven upwelling in the Southern Ocean emerges as a key stabilizing mechanism. For a collapse to occur, this upwelling must be offset by downwelling in the Pacific. While a Pacific Meridional Overturning Circulation (PMOC) develops in many models under extreme forcing, it remains too weak to fully compensate. As a result, an AMOC collapse appears unlikely this century. These findings highlight the importance of improved ocean observations and modeling"particularly in the Indo-Pacific and Southern Ocean"to reduce uncertainty in future AMOC change and its climate impacts.

Bio(s): Jon Baker is a Senior Scientist in the UK Met Office's Ocean, Cryosphere and Climate Team, where over the past five years he has developed and evaluated global ocean reanalyzes and studied the Atlantic overturning circulation using state'of'the'art climate models and observational datasets. He completed his PhD at the University of Exeter, investigating the dynamics of the global ocean overturning circulation. Jon's research now focuses on understanding historical variability in the overturning circulation and its future evolution under global warming.

Title: Partnering Science and Practice: Using Genomics to Guide Resilient Eelgrass Restoration

Presenter(s):

• Jessie Jarvis, University of North Carolina Wilmington
• Stephanie Kamel, University of North Carolina Wilmington
• Erin Shields, Chesapeake Bay National Estuarine Research Reserve in Virginia

Sponsor(s): This webinar is sponsored by the NERRS Science Collaborative

Seminar Contact(s): Doug George (douglas.george@noaa.gov) or Nick Soberal (nsoberal@umich.edu)

Remote Access: https://umich.zoom.us/webinar/register/WN_SPnA5OukSNaWb-tfv53uvQ Abstract
In recent years, rising summer temperatures have caused large-scale diebacks of eelgrass (Zostera marina) meadows in parts of the lower Chesapeake Bay, shifting these once-stable habitats toward lower-density, ephemeral states. These losses threaten the vital ecosystem services that eelgrass provides, from supporting fisheries to stabilizing shorelines. With climate change accelerating, coastal managers and restoration practitioners increasingly recognize that long-term eelgrass restoration success must account for the species' resilience to thermal stress. However, critical knowledge gaps remain about which eelgrass populations may be best suited for future restoration under warming conditions.To help fill these gaps, this project compared eelgrass populations in Virginia and North Carolina to identify traits and genetic markers associated with thermal resilience. The team conducted genomic analyses and reciprocal transplant experiments to evaluate how different populations respond to heat stress and to test which seed sources might perform better under future climate scenarios. In this webinar, project collaborators will share key findings from this work and introduce several practical products developed through the project, including an eelgrass restoration decision-making framework, a standard operating procedure (SOP) for seed-based restoration, and guidance for integrating genomic data into management decisions.

Abstract: A sharp phase transition occurs when snow becomes rain in the atmosphere. When rain falls instead of snow, it decreases the land surface albedo, decreases land surface water storage, enhances ice sheet melt, and has impacts on human infrastructure. In this work, we assess this atmospheric snow-to-rain transition using high-frequency outputs from earth system models and spaceborne radar observations. To be conservative and focus on impactful precipitation events, we use the 275 K air temperature isotherm in the bottom atmospheric level during large (>5 mm/day, > 1 dBZ) precipitation events as a proxy for snow-to-rain transitions. Over Greenland, we find present-day rain observations consistent with rain are rare, occurring only along the coasts and during the summer. Applying warming alone we can constrain possible additional rain that could fall. We find rain doubles with 2.3 degrees C of near-surface warming. Next, we assess the snow-to-rain transition during the northern hemisphere water year (October to April). During the early 21st century, this isotherm spans 10 degrees of latitude. Starting at 44 degrees North in October, it moves equatorward to 34 degrees North in January/February and then returns poleward to 42 degrees North in April. Under ~3 degrees of global warming, the isotherm moves poleward by 4.4 degrees latitude (~500 km). The 21st poleward isotherm shift exceeds the climatological month-to-month isotherm migration, especially during the coldest months (January, February). Additional analysis is focused on geographic variations and on the sensitivity of these results to conditioning based on precipitation occurrence. Overall, these results provide new insights into where snow becomes rain during impactful atmospheric events.

Each webinar will highlight different aspects of Sargassum research, management, and its impacts on coastal communities and ecosystems. The goal of this series is to foster knowledge-sharing and regional collaboration across affected areas. This webinar, presented by Amy Dempsey, is the fourth in a series of five webinars looking at the recent issues surrounding Sargassum Inundation Events.

As Sargassum inundations intensify across the Caribbean, coastal communities and resort operators face mounting challenges in managing the environmental and economic impacts. This presentation explores current best practices and technologies for Sargassum collection and containment, both onshore and offshore, with a focus on environmental and regulatory considerations. Drawing on successful deployments of floating barriers in St. Thomas, we will detail how resorts, once forced to close for weeks due to overwhelming accumulations, are now using containment systems to efficiently capture and remove Sargassum while minimizing beach erosion and sand loss. Case studies from two distinct resort sites illustrate how site-specific variables such as habitat type, sea state, and wind conditions influence anchoring methods and barrier design. We will share practical lessons learned, evolving installation strategies, and highlight what's working in the ongoing effort to better control and collect Sargassum with minimal environmental disruption.

Bio(s): Ms. Dempsey founded Bioimpact, Inc. in 1986 and has been doing environmental consulting since that time. Trained as a marine biologist, Ms. Dempsey came to St. Croix, USVI as an aquanaut for NOAA's undersea habitat. She has been working with resorts to address the Sargassum issue over the last five years, and helped produce the Sargassum Blueprint for the U.S. Virgin Islands Department of Planning and Natural Resources.

Title: Aquatic Acoustics: Listening to Fish in the Hudson River National Estuarine Research Reserve

Presenter(s):

• Aaron Rice, Cornell University
• Maija Niemist, New York State Department of Environmental Conservation
• Rebecca Cohen, Cornell University

Sponsor(s): This webinar is sponsored by the NERRS Science Collaborative

Seminar Contact(s): Doug George (douglas.george@noaa.gov) or Nick Soberal (nsoberal@umich.edu)

Remote Access: https://umich.zoom.us/webinar/register/WN_Ri6zN5LkT-i6JSvtC_pBnw Abstract
The Hudson River Estuary is a dynamic and complex environment that supports a wide range of fish, including a number of migratory and endangered species. Advances in marine ecosystem technologies, which include the use of passive acoustic monitoring, have enabled the Hudson River Reserve to address critical management challenges including understanding how fish species use the Hudson River Estuary, monitoring species population dynamics of protected and endangered animals, and creating engaging communication tools that inspire public stewardship of key fish species. The management of key fish within the estuary is a priority for the Hudson River Reserve; several key species remain data deficient and critical questions remain, particularly regarding phenology and spatial patterns of habitat use. To address these needs, this collaborative research project implemented a passive acoustic monitoring approach to target information gaps related to focal fisheries ecology and management within the reserve sites and adjacent estuarine habitats. In this webinar, members of the project team will share findings from their project, including their characterization of a diverse range of soundscapes across latitudinal and salinity gradients along the Hudson River, and comparisons of sounds from tributary and wetland habitats to those of the main channel of the river. They will also discuss their collaborative approach and how the project has strengthened relationship-building efforts among regional partners, students, and intended users.

Overview: NOAA's Southeast and Caribbean Regional Collaboration Team (SECART) is launching a webinar series to raise awareness about key issues surrounding Sargassum. Each webinar will highlight different aspects of Sargassum research, management, and its impacts on coastal communities and ecosystems. The goal of this series is to foster knowledge-sharing and regional collaboration across affected areas. This webinar, presented by Dr. Brad Whalen and Dr. Ira Levine, is the fifth and final in a series of five webinars looking at the recent issues surrounding Sargassum Inundation Events.

The availability of 5-50 million tons of landed Sargassum biomass represents an opportunity for the development of new products throughout the Caribbean and surrounding areas. Collection, stabilization and transport remain a challenge which has been the topic of intense efforts along with the commercial conversion of Sargassum biomass into valuable products. Products range from food, feed, fuels, construction material, dyes, nutraceuticals, cosmeceuticals, etc. Investment in collection and processing facilities is dependent on the reduction of risk surrounding biomass availability. The development of feedstock logistic systems for Sargassum are essential for realizing its potential as a feedstock for a variety of commercial applications. Approaches are needed for harvesting and collecting Sargassum that minimize costs and prioritize stability and quality. With its high moisture and ash content, transportation distance is an important consideration to produce any bioproduct. Sargassum availability varies from location, day to day, seasonally (April " October) and annually. Biorefinery operations rely on a constant supply of feedstock. Effective storage solutions can ensure that high quality biomass is available throughout the year. Current research addressing these concerns will be presented as well as existing research gaps.

Bio(s):

Dr. Brad Wahlen has been developing biomass preprocessing approaches within the Feedstock Technologies Department at Idaho National Laboratory for the past 11 years. His focus has included enzyme technologies to improve biomass processing, storage approaches for agricultural residues, ash reduction in both microalgae and seaweed and preservation techniques for stabilizing wet feedstocks like micro- and macroalgae.

Dr. Levine was awarded 2016-2017 U.S. State Department's Distinguished Chair Fulbright and the 2009-2010 Fulbright New Century Scholar. His 45 years of algae farming and cultivar enhancement experience includes work in Canada, Chile, China, Fiji, India, Indonesia, Italy, Japan, Malaysia, Philippines, and USA. Dr. Levine authored 36 publications, 105 presentations in 46 countries (including the United Nations, US Congress, & NBC TV), 4 book chapters, 3 books and 29 grants ($ 10,025,000).

Abstract: The impact of an eddy-resolving ocean as compared to an eddy-permitting ocean in the U. S. Navy's Earth System Prediction Capability (ESPC) global coupled system on ocean and atmospheric forecast skill is examined. The use of an eddy-resolving (1/12 o ) ocean provides clear benefits to ocean forecasting skill compared to the use of an eddy-permitting (1/4 o ) ocean initialized using the eddy-resolving ocean analysis. The eddy-resolving ocean reduces RMSE for mixed layer depth, sea surface height anomaly, and upper-ocean temperature and salinity by as much as 20% throughout the 45-day forecast integration lead times over forecasts using the eddy-permitting ocean. The impact of eddy-resolving scales is particularly important in the energetic western boundary currents with over 50% reduction in the SST biases in the Gulf Stream and Kuroshio Extension by the end of the 45-day forecasts, although the warm bias along the immediate east coasts of Asia and North America are increased. These ocean improvements result in reductions of air temperature bias magnitudes at long lead times, most notably over the tropics and southern extratropics. However, the impact on other atmospheric skill metrics is near neutral.

Abstract: This seminar presents results from the NOAA EPP Graduate Fellow's one-year in-residence at NOAA Hollings Marine Lab in Charleston, SC. This fellowship was conducted with NOAA mentor Dr. Marie DeLorenzo of the NOS/NCCOS Ecotoxcology Branch. Tire wear particles (TWPs), a significant source of microplastic pollution, introduce toxic chemical additives such as6PPD and its transformation product 6PPD-quinone (6PPD-Q) into aquatic environments via urban runoff. While the acute toxicity of 6PPD-Q has been established in freshwater species, its effects on estuarine organisms remain poorly understood. This study investigates the toxicological impacts of TWP leachate, 6PPD, and 6PPD-Q on Cyprinodon variegatus (sheepshead minnow), a model estuarine species. Using a 96-hour exposure assay, 24h post-hatch larval minnows were subjected to increasing concentrations of 6PPD (under UV light), 6PPD-Q, and diluted TWP leachate. Results revealed no mortality from6PPD-Q at concentrations up to 500 g/L but demonstrated significant mortality with exposure to 6PPD and TWP leachate, indicating that the presence of unidentified degradates of 6PPD and/or toxicants in the TWP mixture are leading to mortality rather than 6PPD-Q alone. To explore this, both targeted and non-targeted chemical analyses were conducted. While targeted methods employing solid-phase extraction (SPE) for sample preparation and LC-triple quadrupole mass spectrometry (LC-MS/MS) with native calibration curves for quantification were used to measure 6PPD-Q concentrations, non-targeted high-resolution mass spectrometry (HRMS) was employed to screen for additional, uncharacterized compounds potentially driving toxicity. This research establishes acute toxicity thresholds for TWP contaminants in estuarine systems and underscores the importance of assessing the chemicals in TWPs in environmental risk evaluations. Our findings offer critical insights into the ecological risks associated with TWPs in coastal ecosystems and inform regulatory frameworks for emerging tire-derived pollutants.

Title: Wavelet Ocean Data Assimilation

Abstract: Due to necessary assumptions of observational errors with an exigency for appropriate and timely inversion in the assimilation, dense observations are thinned and/or altered before being assimilated into ocean models. Historically, this process did not significantly restrict model skill because most of the observation types had a quite coarse horizontal distribution. However, recent advances in observation resolution demand new assimilation approaches, whereby small-scale features are actively corrected in the model background. A novel method is introduced that applies multiscale data assimilation utilizing the wavelet transform. Unlike other currently employed ocean multiscale techniques, this method is performed in a single analysis step. Utilizing the wavelet transform allows for observational information to be retained at all its original grid points, compared to the averaging and removal in traditional techniques, such as super observations. This comes from the unique space and frequency relation available to the wavelet transform, which instead filters the potentially correlated small-scale observation errors at each model grid point. Several six-month identical twin data assimilation experiments were used to validate the method. Results indicate comparable to substantial improvements over super observations. On average, the sea surface temperature RMSE was 39 % lower for the wavelet method over the six-months compared to super observations. The wavelet method was also able to constrain horizontal scales in assimilation 29 km and above compared to 60 km and above for the super observations.
