Abstract: Outside of official public engagement forums, preferences about offshore wind energy development generally remain unknown for members of the public. Few studies on offshore wind energy development focus on the relationships among social values, support level, and participation in social action and civic engagement. These gaps in information limit understanding about the effect of offshore wind energy development on coastal communities. To address these gaps, NCCOS social scientists conduct community characterizations in areas where BOEM is proposing offshore wind energy development. With this information, we determine how a multitude of social factors influence community support for, or opposition to, offshore wind energy development, as well as provide BOEM with information on social action and civic engagement intentions and preferences. Results from a recent community characterization from the Carolinas will be presented, as well as updates from ongoing work in Oregon.

Title: Leveraging satellite observations for freshwater monitoring on Cape Cod


Presenter(s): Megan Coffer, GST

Abstract: Secchi disk depth was evaluated for nearly 400 freshwater ponds across Cape Cod, Massachusetts, using Landsat and Sentinel-2 satellite imagery. A random forest model was generated to predict satellite-estimated Secchi disk depth based on field-measured Secchi disk depth. Then, a time series of Secchi disk depth was generated for nearly 400 ponds across the Cape using satellite observations. Results indicated that Secchi disk depth changed significantly in 16 ponds across the Cape, with all but one pond indicating decreased water clarity conditions. This project directly fulfills a stakeholder request made by the Cape Cod Commission to improve their spatial and temporal capacity for monitoring water quality across the Cape.

Title: Fungal Controls of Phytoplankton in Changing Oceans

Presenter(s): Syrena Whitner, University of Hawai'i at Manoa

Sponsor(s): IRC Seminar Series, Honolulu HI

Seminar Contact(s): kate.taylor@noaa.gov

Location: Webinar

Remote Access: Connect with Google Meet: https://meet.google.com/tdm-bwnz-uiyVia phone: (661) 527-2839, and enter PIN: 251 826 738#

Abstract: Phytoplankton size distributions are a powerful predictor of long-term marine food webs and fisheries health. A lesser-considered impact of global climate change on phytoplankton is how ocean warming and acidification will increase their susceptibility to pathogens such as marine fungi. Our research investigates the diversity, rates, and specificity of marine fungi predating near-shore phytoplankton, using a mesocosm experiment. With a multi-'omics approach, we are testing prediction that global change will decrease the specificity of interactions while increasing infection rates. We hope to incorporate our results into predictive models supporting proactive ecosystem-based management.

Sponsor(s): NOAA Central Library and NOAA Ocean ExplorationSeminar Contacts: library.seminars@noaa.govLocation: Webinar

Remote Access: https://attendee.gotowebinar.com/register/5763694260374024277

Accessibility: Captions are added to the recordings of presentations once uploaded to the NOAA Central Library YouTube Channel. Sign language interpreting services and closed captioning are available, but need to be requested at least 5 days before the event.Summary: Artificial features including shipwrecks and energy infrastructure shape the biogeographic patterns of macro-organisms in shelf and slope environments; how they influence microorganisms is unclear. Historic shipwrecks are abundant, isolated habitats with global distribution, providing a means to explore contemporary processes shaping marine biogeography. Shipwrecks may function as islands of biodiversity for microbiomes, creating a patchwork of habitats with influence radiating out into the seabed. This presentation will provide case studies of the impact that built structures in the Gulf of Mexico have on microbiome richness and diversity in the surrounding environment. The presentation will also provide evidence of an island effect on seabed microbiomes and the emergence of ecological transition zones where built habitats meet the surrounding environment. The goal of this work is to provide new information on how the built environment shapes microscopic life on the seabed.Keywords: Shipwrecks, deep-sea, microbiology

Abstract: Juvenile snow crab habitat in the Chukchi Sea was studied during a period of ocean warming. During a cold year early in study, most juvenile crab of all sizes inhabited cold (<2C) areas. In later years, the smallest size classes were restricted to cold areas, or were effectively absent, and larger juveniles were present in warmer areas. Juvenile snow crab could be impacted by the recent reduction in habitat with cold summer bottom temperature in the Chukchi Sea (and Bering Sea).

Title: Analyzing Patterns of Recruitment in Ten Species of US South Atlantic Reef Fishes

Presenter(s): Kaitlynn Wade, NOAA/Office of Education, Educational Partnership Program with Minority Serving Institutions (EPP/MSI)

Sponsor(s): NOAA EPP/MSI Cooperative Science Centers

Seminar Contact(s): oed.epp10@noaa.gov, Audrey.Trotman@noaa.gov, kwade@umces.edu

Location: Webinar

Abstract: Atlantic reef fishes off the southeastern United States support a multispecies fishery that is commercially and ecologically important. Several of these species have experienced recent (since 2010s) low recruitment, but the underlying causes are unknown. In an effort to understand the potential drivers of low recruitment, the autocorrelation and partial autocorrelation for each of ten species were analyzed using recruitment estimates from the most recent stock assessments. Results indicate that nine of the species experienced a significant autocorrelation at lag one, and three species also showed decadal cyclic patterns. Correlations and PCA analyses categorized these species into two groups: species that have experienced recent low recruitment and species that have not. This project also evaluated the hypothesis that fishing is a main driver causing low recruitment, which was concluded to be unlikely based on metrics that were tested through simulation scenarios and applied to fishing and recruitment estimates for each species.

Bio(s): The presenter is Kaitlynn Wade. Kaitlynn is a current Master's student from the University of
Maryland Center for Environmental Science at the Chesapeake Biological Laboratory (UMCES-

NOAA Science Seminar SeriesTitles: "Quantification of Soil Carbon Flux from Spartina alterniflora Living Shorelines" "Exploring Pathways of PFAS from Sources to Drinking Water Intakes in the Great Lakes and the Environmental Justice Impacts"

Presenter(s): David de la Garza, NOAA CCME-II Graduate Scholar and MS student, University of Texas Rio Grande Valley Andrea Pugh, NOAA CCME-II Graduate Scholar and PhD Candidate, Florida A&M University

Sponsor(s): NOAAEPP/MSI Cooperative Science Centers

Seminar Contact(s): oed.epp10@noaa.gov, Audrey.Trotman@noaa.gov, david.delagarza03@utrgv.edu, andrea1.pugh@famu.eduLocation: WebinarAbstracts: Living shorelines are important management strategies to reduce coastal erosion, improve coastal community resiliency, provide valuable habitat to various flora and fauna, and act as storage (sink) and release (source) of carbon. The release of carbon through greenhouse gas emissions, namely carbon dioxide and methane (also called soil carbon fluxes), play an important role in the global carbon cycle and greenhouse gas effect. The implementation of living shorelines as a method to offset anthropogenic carbon release requires research with respect to the age of living shorelines and their ability to effectively capture carbon. This seminar presents results from a project investigating the soil carbon fluxes and carbon stock of constructed living shorelines of different ages (1-44 years) and one natural reference site.
Perfluoroalkyl substances (PFAS) are a man-made group of chemicals that are widely distributed in nature, mostly due to their use as surfactants and emulsifiers, as well as their persistence in the environment. Human exposure to PFAS is likely to include thyroid effects, cholesterol changes, multiple cancers, liver tissue damage, immune effects, and development effects to fetuses during pregnancy or breastfed infants. Interest in PFAS has piqued recently due to their emergence as contaminants in the Great Lakes Region. There is limited knowledge of the behavior of Perfluoroalkyl substances (PFAS) in aqueous environments and the pathways by which they reach water intakes for human consumption. PFAS have been found in water supplies sourced from the surface water of Lake Huron and Michigan. Rivers with substantial industrial activity, like the Saginaw and Grand Rivers, are believed to be major sources of PFAS to the Great Lakes. A Finite Volume Community Ocean Model (FVCOM) simulation based on NOAA's Lake Michigan-Huron Operational Forecast System was used to estimate dispersion patterns for Perfluorooctane sulfonate and Perfluorooctanoic acid throughout the lakes from their major routes of entry (rivers). The model results are analyzed together with historical and newly collected water samples from the region to identify links between riverine input of contaminants and water intake sites, as well as their variability throughout the year. These results are synthesized to provide recommendations for prioritization of site remediation, monitoring strategies, and target reductions in PFAS inputs to the Great Lakes. This research will help guide policy to help protect both human and environmental health and support states and municipalities developing PFAS standards and policies that address water quality and availability challenges.

Bio(s): David de la Garza is a NOAA Center for Coastal and Marine Ecosystems II (CCME-II) graduate scholar in Cohort 1 at the University of Texas Rio Grande Valley.

Her passion for Environmental Science/Justice spurred from growing up in a post-industrial city, Saginaw Michigan, participating in environmental science research since the age of nine. Andrea's research interests are contaminant chemistry and environmental justice. Her PhD dissertation involves determining the potential transport pathways of per-fluorinated compounds (PFAS) from river sources to drinking water intakes in surface waters of the Great Lakes. This is a topic driven by environmental justice issues important to Great Lakes communities.

Title: How oceanographic conditions shape early rockfish survival in the California Current and plans to translate this work to pollock in the Gulf of Alaska and Biogoechemical modeling of the Northeast Pacific; past, present, and future resources for fisheries oceanography
Part of NOAA EcoFOCI Seminar Series

Presenter(s): Will Fennie, NOAA Alaska Fisheries Science Center; and Al Hermann, NOAA Cooperative Institute for Climate, Ocean, & Ecosystem Studies at the University of Washington


Sponsor(s): This seminar is part of NOAA's EcoFOCI bi-annual seminar series focused on the ecosystems of the North Pacific Ocean, Bering Sea and U.S. Arctic to improve understanding of ecosystem dynamics and applications of that understanding to the management of living marine resources. Since Oct 21, 1986, the seminar has provided an opportunity for research scientists and practitioners to meet, present, develop their ideas and provoke conversations on subjects pertaining to fisheries-oceanography or regional issues in Alaska's marine ecosystems, including the US Arctic.

Abstract: This seminar will discuss modeling and observational tools employed in the EcoFOCI program including techniques from the California Current system to study how ocean conditions experienced in early life affect fish species growth and survival and a brief history of our modeling activities, the present status of model products, how we serve these to the public, and our plans for the future. Over several decades at the Pacific Marine Environmental Laboratory we have applied numerical models to infer past, present and future states of these regional oceans and their biota. These estimates are provided to fisheries scientists to help identify local biophysical dynamics, and to managers to help develop effective management strategies in the face of short- and long-term environmental changes. As global warming generates extreme ocean conditions (i.e., marine heatwaves) we can gain insight into how larval fish growth and mortality will change in warmer conditions. The California Current Large Marine Ecosystem experienced anomalous ocean warming from 2014 to 2016, creating novel conditions. Otolith microstructure of juveniles of the economically and ecologically important black rockfish (Sebastes melanops) collected from 2013 to 2019 were examined to quantify the implications of changing ocean conditions on early growth and survival.

Bio(s):Will Fennie is a research oceanographer in the EcoFOCI group at the NOAA AFSC. Will's work uses otolith microstructure analysis to understand how oceanographic conditions during early life affect larval and juvenile fish growth and survival. Al Hermann collaborates with physical oceanographers, biologists and chemists on numerical models of the Bering Sea, Gulf of Alaska, and Pacific Northwest as part of the EcoFOCI group at NOAA PMEL. Increasingly this work is focused on model-based regional downscaling of anticipated global climate change. Related work centers on 3D visualization of physical and biological model output; this includes individual-based models of fish.

Title: Observations of river plume mixing in the surf zone

Presenter(s): Samuel Kastner, Western Washington University

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

Abstract: We use salinity observations from drifters and moorings at the Quinault River mouth to investigate mixing and stratification in a surf-zone-trapped river plume. We quantify mixing based on the rate of change of salinity DS/Dt in the drifters' quasi-Lagrangian reference frame and estimate a constant value of the vertical eddy diffusivity of salt of Kz = (2.2 0.6) - 10'3 m2 s'1, based on the relationship between vertically integrated DS/Dt and stratification, with values as high as 1 - 10'2 m2 s'1 when stratification is low. Mixing, quantified as DS/Dt, is directly correlated to surf-zone stratification, and is therefore modulated by changes in stratification caused by tidal variability in freshwater volume flux. High DS/Dt is observed when the near-surface stratification is high and salinity gradients are collocated with wave-breaking turbulence. We observe a transition from low stratification and low DS/Dt at low tidal stage to high stratification and high DS/Dt at high tidal stage. Observed wave-breaking turbulence does not change significantly with stratification, tidal stage, or offshore wave height; as a result, we observe no relationship between plume mixing and offshore wave height for the range of conditions sampled. Thus, plume mixing in the surf zone is altered by changes in stratification; these are due to tidal variability in freshwater flux from the river and not wave conditions, presumably because depth-limited wave breaking causes sufficient turbulence for mixing to occur during all observed conditions. This has implications for predicting the transport of pollutants, nutrients, and sediment delivered to the coastal ocean by small rivers.

Abstract: We will describe the changing conditions in the southeastern Bering Sea and estimates of ocean productivity from moored instruments at NOAA site M2. The biophysical mooring at M2 has marked the changes in the Bering Sea for 29 years. Patterns of primary productivity in the Bering Sea, which typically consist of a spring bloom, intermittent summer production, and a possible fall bloom are of importance to the ecosystem and fisheries in the region that depend on this influx of organic material. An important productivity metric, net community production (NCP) is considered to be an estimate of the maximum organic carbon available to be exported out of the surface ocean, with implications for the ecosystem, fisheries, carbon budgets, and climate modeling. NCP rates were estimated based on the oxygen/nitrogen (O2/N2) ratio from instruments deployed on the M2 mooring in the Southeastern Bering Sea in 2021, and will be discussed here in concert with productivity estimates from other methods and co-located sensors. The biophysical mooring at M2 has marked the changes in Bering Sea for 29 years.

Bio(s): Haley Cynar is a PhD student at Oregon State University in the College of Earth, Ocean, and Atmospheric Sciences, with a concentration in Ocean Ecology and Biogeochemistry. Her research focuses on measures of ocean productivity using dissolved gases and isotopes as tracers of biological productivity. Phyllis Stabeno is a physical oceanographer at Pacific Marine Environmental Laboratory. She conducts research into the impacts of climate change on high-latitude marine ecosystems.

Title: Autonomous High-Resolution Ocean Floor Mapping

Presenter(s): Andrew March, MIT LL, Lexington MA, FFRDC, Undersea Systems and Technology, Asst. Group Leader

Sponsor(s): Integrated Ocean and Coastal Mapping (IOCM) Seminar SeriesSeminar Contacts: Andrew March, amarch@ll.mit.edu; Amber Butler amber.butler@noaa.gov, iwgocm.staff@noaa.govLocation: Webinar

Remote Access: https://register.gotowebinar.com/register/2211659274259940958

Abstract: Mapping of the ocean floor has been identified as an international grand challenge because no existing technology offers both high-resolution and fast coverage rate. Meter-scale resolution seafloor maps, necessary for applications such as search and resource exploration, are obtained by sending sensors deep into the ocean " a slow and difficult approach to mapping large areas. Low-frequency sonar can propagate across the long distances underwater potentially providing fast coverage, but diffraction and ship size constraints limit the attainable resolution. A novel future mapping capability could deploy a small fleet of USVs to create a sparse array ten to a hundred times larger than existing, fixed hull-mounted arrays. The larger effective array produces a narrower beam enabling higher resolution maps at deeper depths. To demonstrate that this is feasible, our team conducted a series of risk reduction efforts culminating in the deployment of a rigid sparse aperture sonar array (8 m - 8 m) in Cape Cod Bay.
