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

Remote Access: https://meet.goto.com/790486565
Or on your phone Access Code: 790-486-565, United States: +1 (646) 749-3129

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.

Title: Prevalence of algal toxins in gray whales feeding in Northwest Washington, USASeries: National Marine Sanctuaries Webinar Series

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.

Title: eDNA Monitoring in the National Estuarine Research Reserves; Lessons on Standardization, Communication and Implementation

Part of the NOAA Omics Seminar Series

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.

Title: Advancing natural resource management assessments in Pacific Island communities with uncrewed aerial vehicle and geospatial datasets (RECORDED)
Coral Collaboration Monthly Seminar

Presenter(s): Romina King, University of Guam, and Molly Chambers, Guam Coral Reef Initiative

Sponsor(s): NOAA Coral Reef Conservation Program

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.

Title: Navigating Coexistence: Ecological drivers and social implications of predator-induced regime shifts in the Northeast Pacific

Presenter(s): Jenn Burt, Ph.D. , BC Marine Program Lead, Nature United and Simon Fraser University

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.

Title: Building Bridges: New marine mammal research and collaborative opportunities at University of Washington

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.

Recordings: The presentation will be recorded; once captioned it will be hosted on the archived webpage: https://sanctuaries.noaa.gov/education/teachers/webinar-series-archives.html.

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.

• Bria Brooks, Florida Public Archaeology Network

Sponsor(s): This webinar is sponsored by the NERRS Science CollaborativeSeminar Contacts: Doug George (douglas.george@noaa.gov) or Nick Soberal (nsoberal@umich.edu) AbstractNestled along Florida's northern Gulf Coast, the Apalachicola River and Bay system is a landscape rich in both natural and cultural heritage. For over 12,000 years, this region has supported diverse ecosystems and communities, from Indigenous groups to early industries like cotton, timber, and fishing. The area now faces mounting challenges, however: the impacts of climate and the subsequent loss of historical sites threaten the preservation of these communities' stories. Ranking as one of Florida's most under-resourced areas, there is an urgent need to document and preserve the region's heritage while fostering connections with its current residents.This webinar will spotlight the "People of the Apalachicola System" project, which combines archaeological research, digital modeling, and innovative community engagement to understand and protect the area's cultural landscape within the Apalachicola National Estuarine Research Reserve. Participants will learn about the project's approach, including methods for engaging local voices through workshops and surveys, as well as how these efforts address threats to heritage resources. The webinar will also share preliminary findings, highlight effective strategies for fostering collaboration, and explore how these lessons can guide future preservation and education initiatives in similar at-risk areas. Join the session to discover how heritage and community are coming together to protect the stories of Apalachicola's past and shape its future!

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.

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.

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.

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.

Title: Nighttime Lights and Urban Heat: A Six-YearAssessment of Major U.S. Cities Using Multi-Satellite Observations

Presenter(s): Shawn Preston, NOAA NESDIS,JPSS/LEO Pathways

Sponsor(s): NOAA LEO Program

Seminar Contact(s): Bill Sjoberg bill.sjoberg@noaa.gov

Location: Webinar

Abstract: Urban Heat Islands (UHIs) drive up temperatures in densely built environments, affecting everything from energy consumption and public health to local ecosystems. This study uses data from multiple satellite platforms"including NOAA's Visible Infrared Imaging Radiometer Suite (VIIRS),NASA's Landsat 8 Surface Reflectance, and Google's Dynamic World Land Cover"to explore how 21 major U.S. cities (three in each region outlined by the Fifth National Climate Assessment) experienced summer heat from 2017 to 2023. UHI intensity is measured by comparing land surface temperatures in urban areas to those in nearby rural regions, while VIIRS nighttime radiance helps illustrate the extent of urban development. Our findings show a clear pattern: cities with brighter nighttime lights tend to have stronger UHIs, underscoring how factors like population density, building materials, and available green space can shape local heat conditions. By spotlighting the summer of 2023"one of the hottest on record just before 2024"we see how global warming may be intensifying these urban heat challenges. We also factor in extreme heat days(those in the top 5% of maximum temperatures), revealing a strong link between UHI intensity and the frequency of extreme hot days. These insights highlight the pressing need for measures such as planting more trees, using reflective surfaces, and adopting other cooling strategies to help cities cope with rising temperatures and bolster resilience.

Title: Examining Oyster Reef Fauna Using Emerging, Non-invasive and Traditional Sampling Techniques

Presenter(s):

• Matt Kimball, Baruch Marine Field, Lab University of South Carolina
• Robert Dunn, North Inlet-Winyah Bay NERR

Sponsor(s): This webinar is sponsored by the NERRS Science CollaborativeSeminar Contacts: Doug George (douglas.george@noaa.gov) or Nick Soberal (nsoberal@umich.edu) AbstractFoundation species such as the eastern oyster (Crassostrea virginica) serve numerous ecological functions and provide myriad ecosystem services within coastal environments. These reefs improve water quality, stabilize the adjacent salt marsh, and provide key habitat for approximately 300 species, including fishes, shrimps, and crabs, among other fauna. However, due to overfishing, disease and other stressors, oyster reef habitat has declined drastically. With increased conservation and restoration efforts to increase oyster reef quantity, there is a need for a more holistic understanding of oyster reef condition and function for reef-associated fauna.In 2023, a Catalyst team comprising 4 Reserves and 4 university partners sampled oyster reefs across the southeast. The team used traditional sampling, acoustic imaging, stable isotope analyses, oyster disease assays, and environmental DNA to characterize the community of reef-associated fauna. Following the field campaign, the team held two project meetings and a virtual workshop to engage directly with intended users. In this webinar, the project team will share the high-level takeaways from their sampling, describe the successful user engagement process, and gauge interest in further participation by Reserves from across the System.

Title: Unraveling the Residence time of a Subtropical Estuary: Modeling Impacts of Climate Change and Extreme Events

Presenter(s): Paula Birocchi (U. So Paulo)

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

SeminarContact: Alexander.Kurapov@noaa.gov

Abstract: This study investigated the effects of freshwater discharge variability on residence time. We have quantified the estuarine and freshwater residence times under climate change and extreme events. The Estuarine and Coastal Ocean Model (ECOM) was coupled with the Opendrift particle tracking model and applied to Canania-Iguape Estuarine-Lagoon Complex (CIELC). In addition, we measured Enterococci and thermotolerant coliform concentrations and calculated the T90 bacteria decay in CIELC. Results revealed that mean bacterial concentrations near the Valo Grande channel (VGC) reached up to 1032 CFU/100 mL for thermotolerant coliforms and 465 CFU/100 mL for enterococci during summer, surpassing legal limits. Freshwater residence times ranged between 5-18 hours at the northern inlet and 37- 115 hours at the southern inlet. Estuarine residence times varied from 6 days to 25 days. Particle retention was highest in the central region of CIELC. Storm tides accelerated particle release through the inlets, contrasting with the atmospheric blocking. Projected river discharge variations under climate change are expected to impact residence time, while T90 bacterial decay indicates that CIELC acts as a sink for bacteria and organic matter.

Title: Decoding the Motivations of Fishers Considering Participation in Citizen Science Projects

Presenter(s): Jennifer Sweeney Tookes, Associate Professor of Anthropology, Georgia Southern University. Tracy Yandle. Bryan Fluech, Associate Marine Extension Director for the University of Georgia

Sponsor(s): NOAA Education and NOAA Library

POC: NOAA Library Seminars (library.seminars@noaa.gov) and Rebecca Funk (rebecca.funk@noaa.gov)

Abstract: This presentation encapsulates a lengthy report submitted to Council in 2024. It summarizes research that was conducted in response to the South Atlantic Fisheries Management Council (SAFMC) request for researchers to study and document the interests, motivations, and concerns of fishermen who might participate in the SAFMC's growing Citizen Science Program. The South Atlantic region is distinctive in its efforts to build a citizen science framework to guide future projects in the region, which offers a unique opportunity to systematically assess possible collaboration in the region.

Our research team addressed this information need by combining (1) a qualitative interview-based mixed method research strategy that provides an in-depth understanding of fisher's motivations and experiences with (2) a tailored sampling and robust recruitment strategy to ensure representative data gathering. This has resulted in a nuanced analysis of fishers' reasoning surrounding their decisions about participating in future SAFMC citizen science efforts. The presentation concludes with recommendations for well-designed citizen science projects that have the greatest chances of success in the South Atlantic region.

Title: The effects of predation on survival of salmonids in the Columbia River Basin: So. Much. Uncertainty

Presenter(s): Grant Waltz and James Lawonn, Oregon Department of Fish and Wildlife.

Sponsor(s): NOAA NWFSC Monster Seminar Jam

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

Abstract: Predation is a major proximate cause of mortality for outmigrating juveniles from Columbia River basin salmonid runs listed under the federal Endangered Species Act (ESA). However, operation and maintenance of the Columbia River hydrosystem and other anthropogenic perturbations appear to be ultimate factors that increase the susceptibility of juvenile salmonids to predation. Nevertheless, predator management may be a crucial strategy to help recover fish populations, partly by ensuring their persistence until hydrosystem-related and habitat-related centerpiece actions can be implemented.

At least five different bird species and four different fish species are known or suspected to consume significant numbers of juvenile salmonids in the Columbia River basin. At least seven of these nine predators are either introduced species, or species that may have been largely absent historically, but colonized the basin following creation of the hydrosystem and contemporary navigation channel. Minimum estimates of cumulative basin-wide predation by colonial piscivorous waterbirds has been as high as 30%"50% of outmigrating juvenile fish for some ESA-listed runs during some years, suggesting avian predation may be a major impediment to fish recovery. The overwhelming majority of these birds nest on artificial habitats that were created outright or substantially enhanced by humans.

Predation rates for piscine predators have been estimated at various times and places in the Columbia and Snake Rivers, and while there are likely appreciable impacts to ESA-listed salmon and steelhead runs, the results are less clear relative to avian predation. Changing abundance and distribution patterns for a variety of avian and piscine predators complicates efforts to estimate predation to ESA-listed salmon and steelhead.

Despite the recognized importance of predation management for recovery of ESA-listed fish, only two of nine avian and piscine predator species are managed on a quasi-basin-wide scale. Of three major avian management plans and one major fish management plan implemented in the basin in recent years, only one has involved sufficient monitoring to test whether fish survival has improved on a reach-specific scale, and none have formally tested whether fish survival has improved on hydrosystem-wide or life-cycle scales. However, evidence associated with two of these plans suggests prey switching or increased recruitment by unmanaged predators may have substantially compensated for anticipated survival benefits for juvenile fish, suggesting management efforts may need to be extended to new locations, and to avian and piscine species that are currently unmanaged on a basin-wide scale. Because of the difficulty in predicting predator management outcomes in complex multi-predator, multi-prey systems, a comprehensive, data-informed food web model of the Columbia River basin and plume would be ideal to help managers better understand potential outcomes related to predator management, and to help guide future management actions.

Sponsor(s): NOAA Climate and Societal Interactions Division: Climate Adaptation Partnerships and Adaptation SciencesSeminar Contacts: Aliya Mejias aliya.mejias@noaa.gov, Genie Bey genie.bey@noaa.gov, Bhaskar Subramanian bhaskar.subramanian@noaa.gov

Abstract: This five-part webinar series features projects funded by the Climate and Societal Interactions (CSI) Division's Adaptation Sciences (AdSci) and Climate Adaptation Partnerships (CAP) programs focused on the research and application of nature-based solutions (NbS), which are actions to protect, sustainably manage, or restore natural or modified ecosystems to address societal challenges, simultaneously providing benefits for people and the environment.Nature-based solutions including green infrastructure (NbS/GI) have been implemented for some time as a multifunctional, decentralized strategy for stormwater management. Locally, the benefits and co-benefits of these systems are well quantified. However, to address regional climate risks, NbS/GI need to be upscaled in non-trivial ways across urbanized landscapes. This upscaling poses several formidable physical, economic, and collaboration-related challenges. Addressing these challenges represents one of the front lines in advancing comprehensive resilience and sustainability planning. This webinar episode will feature how Franco Montalto, CAP's Consortium for Climate Risk in the Urban Northeast (CCRUN), has leveraged funding from CAP and AdSci to advance science to support local action and adaptation at a broader scale.Presentations

Title: Geospatial Artificial Intelligence for Animals

Presenter(s): Christin Khan, Fishery Biologist, NOAA NEFSC

Sponsor(s): Protected Species Division Northeast Fisheries Science Center, NOAA Fisheries

Seminar Contact(s): christin.khan@noaa.gov

Abstract: The recent advancements in very high resolution satellite imagery, cloud computing, and artificial intelligence have tremendous potential for the development of an operational system to detect marine mammals around the world. The Geospatial Artificial Intelligence for Animals collaboration is uniquely situated to develop an operational marine mammal detection workflow by accessing commercial satellite imagery provided by the US Geological Survey to civil agencies through the National Civil Applications Center collected through contracts established by the National Geospatial-Intelligence Agency and the National Reconnaissance Office. Thus we have been able to acquire large volumes of Maxar imagery over known seasonal aggregations of the North Atlantic right whale and the Cook Inlet beluga whale from WorldView-3, WorldView-2, and GeoEye satellites. The Microsoft AI for Good lab has developed an open-source active learning pipeline to process incoming imagery, run an anomaly detector, and serve up interesting objects via a web based platform for subject matter experts to classify and validate. Effectively processing this tsunami of imagery and creating an open-source collaborative workflow within the federal government has highlighted challenges in doing this at scale including cloud storage, cybersecurity requirements, image delivery, variations in image products, and processing methodology used across research groups (pansharpening algorithms, orthorectification, digital elevation models). By sharing our challenges and lessons learned, we hope to further push the field forward into a future where scientists will have another tool in the toolbox as we seek to understand and protect marine mammals around the world.

Bio(s): Christin Khan is a Fishery Biologist in the Protected Species Division at the Northeast Fisheries Science Center in Woods Hole. Dedicated to making a positive impact in the world, she is a passionate conservationist and AI enthusiast with a deep commitment to protecting North Atlantic right whales. Her work focuses on leveraging cutting-edge technology and extensive partnerships to drive real-world change in the field of marine conservation. Currently she is focused on creating an operational system to detect marine mammals with VHR satellite imagery and solving the geolocation challenges around the development of on-demand fishing. Christin currently serves on the Executive Committee at the NOAA Center for Artificial Intelligence and the Brain Trust in Biodiversity and Conservation at XPRIZE.

Title: Liutex " The Past, Current, and Future

Presenter(s): Dr. Chaoqun Liu, Distinguished Professor and Director of the Center for Numerical Simulation and Modeling at the University of Texas at Arlington

Sponsor(s): NOAA/AOML Science Seminar Series

Seminar Contact(s): Jun Zhang (Jun.Zhang@noaa.gov)

Location: Webinar

Abstract: Liutex is the first rigorous mathematical definition of local fluid rotation. Helmholtz originally defined vortices as vorticity tubes of local vorticity maxima in 1858, but vorticity is contaminated by shear. A second generation of vortex identification criteria has been developed based on the scalar eigenvalues of the velocity gradient tensor matrix, including Q, , 2, and c, all of which are dependent on arbitrary thresholds and remain contaminated by shear to some degree. Liutex, the third generation, is a vector whose direction is the local fluid rotation axis defined by the eigenvector of the velocity gradient matrix and whose magnitude is twice the local angular rotation speed. The naturally observed vortex core is the concentration of Liutex lines or local maxima of Liutex. According to the Liutex theory, vorticity should be decomposed to a rotational Liutex, and the non-rotational shear and velocity gradient tensor should be decomposed to shear, stretching and rotation to replace the classical Helmholtz (Cauchy-Stokes) velocity decomposition. The Liutex similarity in the dissipation sub-region in boundary layers has been found, which could be the foundation for Liutex-based subgrid models for large eddy simulations. Discovery of Liutex opens a new method to conduct quantified research on vortex science in turbulence; atmospheric, oceanic, and space sciences; aerodynamics; fluid mechanics and dynamics; and biology.

Bio(s): Dr. Chaoqun Liu received both BS and MS degrees from Tsinghua University, Beijing, China, and a PhD from the University of Colorado at Denver. He is currently the Tenured and Distinguished Professor and the Director of Center for Numerical Simulation and Modeling at University of Texas at Arlington, Texas. He has worked on high-order direct numerical simulations and large eddy simulations for flow transition and turbulence since 1990. He has published 16 books, 144 journal articles, and 170 conference papers and book chapters. He is the founder of Liutex and the third generation of vortex definition and identification methods including the Omega, Liutex, Modified Liutex-Omega, Liutex-Core-Line methods, Objective Liutex. He is also the founder of Liutex-based new fluid kinematics.

Title: Grease Under Pressure: What lipidomics can tell us about adaptation throughout the water columnPart of the NOAA Omics Seminar Series

Presenter(s): Jacob Winnikoff, Postdoctoral Scholar in Organismic and Evolutionary Biology at Harvard University

Sponsor(s): NOAA Omics

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

Abstract: Life in the ocean thrives across a vast span of physical conditions, including water temperatures from -2 to 30C (28-86F) and pressures from 1 to over 1000 atmospheres. Most of the adaptations that help marine organisms handle these physical stressors are subcellular in scale, making temperature/pressure adaptation an ideal target for omic exploration. Of the four major types of macromolecule " nucleic acids, proteins, carbohydrates, and lipids " lipids are the most acutely sensitive to changes in temperature and pressure. Lipids are also the main component of membranes that are essential for cells' and organisms' survival. With this in mind, we undertook lipidomic surveys of comb jelly species collected from Hawai'i to the Arctic and from sea level to 4 km depth. These revealed distinct patterns of lipid composition associated with depth and with low temperature. We followed up the surveys with biophysical and synthetic biology experiments to understand the mechanism by which specialized lipidomes help comb jellies tolerate extreme pressure in the deep. The mechanism we discovered explains how shallow-living comb jellies are maladapted to high pressure and also why deep-sea species cannot survive decompression. Our findings have implications for organismal resilience to climate change and for biotechnology. Ongoing work is using lipidomic data to investigate membrane-based pressure adaptation in marine organisms ranging from microbes to mammals. Recent results are presented alongside a tool designed to help the research community detect adaptive signatures in lipidomes.

Bio(s): Jacob Winnikoff is a marine biochemist studying adaptation to extreme environmental conditions. Jacob grew up in and around the temperate waters off southern California. As an undergraduate, he studied the heat-tolerance of intertidal mussels in George Somero's lab at the Hopkins Marine Station, earning his BS in Biochemistry and Biophysics from Stanford in 2016. His graduate work focused on high-pressure adaptation in comb jellies and took place in Steven Haddock's lab at MBARI; it concluded in 2022 with a PhD in Ecology and Evolutionary Biology from UCSC. Jacob was then awarded a NASA postdoctoral fellowship to investigate microbes' tolerance of harsh environments on other ocean worlds. He currently works as a postdoctoral scholar in the Girguis Lab at Harvard on projects involving lipidomics, proteomics, and metagenomics in such diverse marine systems as hydrothermal vents and diving mammals.

Title: Fisheries Science with a SMILE (Size Matters: Innovative Length Estimates)
Coral Collaboration Seminar

Presenter(s): Jen Loch, Post-Doctoral Research Associate for Reef Environmental Education Foundation (REEF) and Julia Byrd, Citizen Science Program Manager for the South Atlantic Fishery Management Council

Sponsor(s): Coral Reef Conservation Program

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

Accessibility: Closed captioning available.

Abstract: Fish lengths are a valuable data source, as they inform biological metrics (e.g., age, sex ratio) and population status. Traditional length data collection methods involve handling or harvesting the fish, which can impact local fish populations. Additionally, harvested fishes frequently represent a limited distribution of sizes and species due to harvest restrictions, while fishery independent methods are often resource limited. The collaborative SMILE (Size Matters: Innovative Lengths Estimates) project will contribute fish length data into stock and ecosystem assessment processes with citizen scientists using single laser-mounted cameras (FishSense). SMILE provides recreational scuba divers (i.e., citizen scientists) with an affordable camera system to capture images of select target species of management priority in the southeast United States (grouper, snapper, hogfish, and parrotfish) through roving diver surveys. Fish lengths are extracted from the images via an AI workflow and length estimations are comparable to existing stereo video methods. Surveys of existing and potential citizen scientist users are being conducted to assess participant motivation, barriers, and impact on diver experience. These surveys will improve project methodology and inform management agencies of the utility of similar citizen science data sources to implement into their assessments.

Bio(s): Jen Loch holds a B.S. in biology from Florida State University, an M.S. in marine biology through the Three Seas Program at Northeastern University, and a Ph.D. in Conservation Biology from the University of Central Florida. Her previous experience includes work as a biology professor at local community colleges in Orlando, an intern at Mote Marine Lab and Disney's Epcot aquarium, and as a conservation lands biologist for a local county government to work with various stakeholders to preserve undeveloped lands for conservation. She enjoys engaging with the public, anglers, and citizen scientists to better understand their knowledge of marine resources to ultimately further conservation through collaboration.Julia Byrd has served as the Citizen Science Program Manager for the South Atlantic Fishery Management Council (Council) since 2019. She oversees the Council's citizen science efforts " helping connect fishermen, scientists, and other stakeholders to develop and support projects that address SAFMC research priorities.

Abstract: The U.S. Department of Agriculture (USDA) Agricultural Research Service has operated a wide variety of watershed research sites for many decades. These are distributed across the U.S. and study pertinent issues for their agroecosystems, including soil moisture, agricultural yield, and hydrologic modeling, among other topics. These study sites were formed into a national network of Long-Term Agroecosystem Research sites, highlighting the value of long-term data series to capture agricultural trends and environmental impacts. However, the viability of these research sites is directly tied to the research conducted there and their ability to evolve to maintain relevance. Presentations will review two long term study sites, the Little Washita and Fort Cobb Watersheds, which have a rich history of soil moisture research and had a major impact on hydrologic science in the past few years.

Title: El Nio related stratification anomalies over the continental slope off Oregon: the potential vorticity mechanism

Presenter(s): Alexander Kurapov (NOAA NOS/OCS/CSDL/CMMB)

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

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

Abstract: Outputs of a regional ocean model centered on the US West Coast are analyzed with focus on the variability along the continental slope. The model is based on the Regional Ocean Modeling System (ROMS), on a 2-km horizontal resolution grid. The model is run without assimilation for a period of 2008-2018 using realistic oceanic and atmospheric forcing. Some analyses involve properties on the isopycnal surfaces 26.5 and 26.25 kg/m3. Off the Oregon coast, the layer between these surfaces is upwelled at the depths of 100-200 m, such that transports in this layer are essential to the shelf-interior ocean material exchange. It was found in the model that the vertical distance between the abovementioned surfaces becomes anomalously large in summer 2014 and 2015. This finding is confirmed by the available ship conductivity-temperature-depth (CTD)data. In other words, the stratification on the slope is found to be anomalously weak. Analyses suggest that seasonal and interannual variability in the slope stratification off Oregon is influenced by the alongslope transport of the potential vorticity (PV). In the nearly geostrophic regime PV can be approximated as f N^2, where f is the Coriolis parameter and N is the buoyancy frequency. Along the slope, the strongest seasonal gradient of PV is found in Oregon, supported by the upwelling, bottom boundary layer processes on the shelf (generating high PV) and shelf-slope material exchange. The advection of this gradient by the poleward undercurrent determines the seasonal PV change late in the summer. In summers2014 and 2015, the PV advection by the anomalously strong poleward current associated with the El Nio oceanic impact explains the negative PV anomaly, or weaker N, on the slope off Oregon.
2023 was another strong El Nio year. Using the CTD data we confirm that a similar effect was observed in this year as well. To see if the El Nio-related stratification anomalies on the slope coincided with the flow anomalies on the shelf, we additionally analyze the ADCP current time series from the NH10 site on the mid-Oregon shelf.

Title: Eternal Evening in the Ocean: Where Mesophotic Coral Ecosystems Thrive

Presenter(s): Philip Yang, PhD Student and NOAA Dr. Nancy Foster Scholar at the University of Rhode Island Graduate School of Oceanography

Sponsor(s): NOAA Office of National Marine Sanctuaries

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

Abstract: Mesophotic, or middle-light, coral ecosystems exist deeper than the shallow coral reefs you might immediately think of. Mesophotic ecosystems can exist across depths of 100 ft (30m) to 350 ft (150m) from the ocean surface. Because of this depth range, these ecosystems occupy as much as 80% of the potential space coral reefs can live in on the seafloor throughout the global tropical ocean. In recent decades, technological advances in diving and robotic vehicles have allowed us to explore and learn more about these diverse and important ecosystems. Come join me to learn more about these ecosystems and what it takes to study them using cutting-edge science!

Title: Sensor-Agnostic Satellite Chlorophyll Model
CoastWatch Seminar Series

Presenter(s): Guangming Zheng, CISESS and CoastWatch Applications Team

Sponsor(s): NOAA CoastWatch


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

Remote Access: Event is completed

Abstract: Satellite-derived chlorophyll-a (Chl-a) data are crucial for monitoring and understanding aquatic ecosystems. However, existing satellite Chl-a products are typically sensor-specific, requiring separate development and calibration for each sensor, which introduces inconsistencies and complicates multi-sensor data merging. This study proposes a novel machine-learning approach that unifies spectral information from diverse sensors by leveraging a transformer-based model. This method compels the model to learn latent representations of both the spectral response functions and top-of-atmosphere (TOA) reflectance, respectively, allowing a single sensor-agnostic model to ingest spectral inputs from multiple sensors.By training on a combined dataset comprising field-measured Chl-a data matched up with coincident MODIS, MERIS, VIIRS, and OLCI observations, the model is able to learn and generalize effectively across diverse band configurations. Results show that the sensor-agnostic model performs comparably to, and often surpasses, four sensor-specific machine-learning models trained separately for each individual sensor, while reducing inter-sensor biases and offering a more unified product.Beyond immediate improvements in accuracy, this transformer architecture demonstrates the potential to build a foundation model in ocean color remote sensing using similar frameworks, enabling more efficient fine-tuning for new sensors or new regions without requiring extensive retraining.

Title: Submerged NC: Lionfish: An Ocean Tragedy in Three Acts

Presenter(s): Dr. Steve Gittings, Chief Scientist of NOAA's Office of National Marine Sanctuaries

Sponsor(s): NOAA, ONMS, Monitor National Marine Sanctuary, and the NC Office of State Archaeology

Seminar Contact(s): Jessica.Frayser@noaa.gov

Abstract: Join Dr. Steve Gittings, Chief Scientist of NOAA's Office of National Marine Sanctuaries, for a front-row seat to a 40-year saga of beauty, death, and survival. Act I: A brilliant new star, the Indo-Pacific lionfish, makes its dramatic debut in the Atlantic Ocean. Mesmerizing at first, it soon horrifies as it leaves disappearance in its wake. Act II: An ecological crisis ensues as native fish succumb to waves of these alien invaders, with no natural defenses to stop them. Act III: Humans enter the scene, combining innovation and brute force to offer Nature a helping hand while it seeks its own footing. Will this epic struggle find resolution? Is it the end of the ocean we know, or a new beginning? Learn how this drama unfolds and what the future holds.

Bio(s): Dr. Steve Gittings is Chief Scientist for NOAA's Office of National Marine Sanctuaries. Initially specializing in coral reef ecology and disturbance, he managed the Flower Garden Banks National Marine Sanctuary before moving to headquarters.

NOAA Science Seminar SeriesWhen: January 8 2025, 12-1 PM ET Where: Webinar and in-person at SSMC4 8th floor large, Silver Spring

Presenter(s): Dr. Nicholas Castillo, Monitoring & Assessment Branch Stressor Detection and Impacts Division National Centers for Coastal Ocean Science, NOAA National Ocean Service

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

Accessibility: Live closed captioning will be provided.

Abstract: In this study, we investigated the incidence and spatial extent of pharmaceutical exposure in marine sportfish, the potential for pharmacological and health effects in fish, pathways of exposure across multiple environmental compartments, and the potential for human exposure via consumption of fish. To do so, we assessed pharmaceutical burden in the recreational sportfish bonefish (Albula vulpes) throughout South Florida and the Caribbean Basin and in red drum (Sciaenops Ocellatus) from 9 estuaries across Florida, analyzing for ~100 different pharmaceuticals. The potential risk of pharmacological effects was determined by comparing pharmaceutical concentrations to a metric of effect based on the human therapeutic plasma concentration (H T PC). Indices of health in red drum (e.g., biochemical and histological state) were quantified and related to measured pharmaceutical concentrations. We used a multicompartment approach to identify pathways of pharmaceutical exposure in bonefish through analysis of bonefish prey items, water, and sediment, and also assessed differential distribution across bonefish internal tissues. Last, we determined the potential for human exposure via consumption of red drum by comparing concentrations to recommended pharmaceutical human daily doses. Across all fish sampled, a total of 53 different pharmaceuticals were detected in 100% of bonefish (mean of 6.3) and 93% of red drum (mean of 2.1), with concentrations exceeding the H T PC metric of effect in 48% of bonefish and 26% of red drum. Relationships between pharmaceutical exposure and biochemical analytes in red drum indicative of liver injury, electrolyte imbalance, and stress were identified. Pharmaceutical concentrations in red drum muscle were low, with a maximum of 0.002% of a recommended human daily dose per serving. Pharmaceutical number, concentration, and composition was unique across environmental compartments, and prey was identified as a potential source of exposure in bonefish. Collectively, this research highlights an important component of water quality for consideration in conservation, fisheries management, and wastewater treatment reform, assesses the possibility of negative repercussions in exposed fish, and explores alternative methods to assess exposure and effect in marine biota.

Title: No need to reinvent the wheel: data assimilation in the age of AI

Presenter(s): Ivo Pasmans (University of Reading)

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

SeminarContact: Alexander.Kurapov@noaa.gov

Abstract: In recent years, there has been a proliferation of studies which apply Artificial Intelligence (AI) to some scientific problem or another. However, in many cases, AI techniques"particularly those in machine learning" used in these studies function as a substitute for, or a variation of, traditional data assimilation methods which aim to combine limited observations with a prior estimate to retrieve the most likely value of the truth. This talk will explore the relationship between AI and data assimilation, focusing on key data assimilation techniques like Kalman filtering, variational methods, and ensemble-based approaches. We will examine the strengths and limitations of these methods and compare them with popular machine learning algorithms. Additionally, promising approaches that integrate machine learning with traditional data assimilation techniques will be discussed, offering new possibilities for enhancing predictive accuracy and computational efficiency in various scientific applications.

Slides, Recordings, Other Materials: TBD

Title: Diving into the timeline for the Fisheries Integrated Modeling System (FIMS), a next-generation framework for assessments

Presenter(s): Kelli F. Johnson, National Stock Assessment Program, Assessment and Monitoring Division, Office of Science & Technology, NMFS, NOAA, Project Lead of the Fisheries Integrated Modeling System

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

Abstract: The Fisheries Integrated Modeling System (FIMS) is a next-generation framework for assessing the status of living marine resources and providing management advice. Its development has been, and will always be, a collaborative effort between employees from several NOAA offices, including representatives from each regional Science Center. Perhaps the most difficult task we have is communicating the timeline for planned development and rollouts, providing training and a user support system, and adding unplanned features. During this presentation we will scroll through the timeline to inform future developers and users where they can dive in.

Keywords: open source; population dynamics; stock assessment

Bio(s): Dr. Kelli F. Johnson received her Masters from Simon Fraser University in 2012 quantifying the spatial use of shipping lanes by blue whales. Two weeks later she started her PhD with Dr. Andr Punt and five years later she started working at the Northwest Fisheries Science Center. Recently, she transitioned to the Office of Science & Technology as the Project Lead of FIMS. She is thankful for this opportunity to help us all learn from each other as we continue to build FIMS.
