Mission and programs · 2024

Mission

The Prince William Sound Science and Technology Institute (d.b.a. Prince William Sound Science Center) (the Center) was formed in 1989 as an Alaska not-for-profit scientific research and education corporation to contribute to the comprehensive description, sustained monitoring, and ecological understanding of Prince William Sound, the Copper River, and Gulf of Alaska. Establishment of the Center followed the Exxon Valdez oil spill, although planning of this institution preceded that event. The underlying philosophy of the Center is to serve as a model for long-term ecosystem management.

Activities or mission (Part I)

To advance community resilience and the understanding and sustainable use of ecosystems.

  • Exxon Valdez Oil Spill Trustee Council Programs:Gulf Watch AlaskaThe Exxon Valdez Oil Spill Trustee Council (EVOSTC) is supporting a long-term monitoring program in the Gulf of Alaska region affected by the 1989 Exxon Valdez oil spill. The monitoring program, called Gulf Watch Alaska, involves more than 25 scientists from multiple agencies, universities, and non-profits and seeks to provide data to identify and help understand the impacts of multiple ecosystem factors on the recovery of injured resources. This program is expected to be 20 years in length but is planned and funded in five-year increments. It builds a legacy of restoration research and monitoring by the EVOSTC and federal and state agencies dating back to 1989. The program includes sites in Prince William Sound, lower Cook Inlet, the Gulf of Alaska, and the outer Kenai Peninsula coast. This year has an overlap between two five-year segments. Mariculture ReCon The Exxon Valdez Oil Spill Trustee Council (EVOSTC) is supporting a mariculture research program. The overall objective of the Mariculture Research and Restoration Consortium (Mariculture ReCon) is to support resporation, habitat enhancement, and economic development through research and partnerships between scientists and seaweed and shellfish farmers. This suite of applied research components takes a farm-centered approach to address EVOSTC restoration, economic development, outreach, administration, and data management interests that overlap top priorities identified by stakeholders and the Alaska Mariculture Development Plan Developed by the Governors Mariculture Task Force. Results will inform shellfish and seaweed production with farmers as full participants in the research.

    Expenses $3,494,711

  • Government Programs:EVOSTC New FacilitiesThe Exxon Valdez Oil Spill Trustee Council is supporting the development of new facilities for the Prince William Sound Science Center. The new facilities include warehouse, office, and research and education spaces. Over $23 million has been pledged to cover costs associated with the new campus. The funds are being administered by the Alaska Department of Commerce, Community, and Economic Development. CORaL NetworkThe Exxon Valdez Oil Spill Trustee Council is supporting an education and outreach program titled, Community Organized Restoration and Learning [CORaL] Network. The purpose is to create and maintain an ongoing framework that builds the capacity of existing resources withing the Exxon Valdez Oil Spill impacted region to ensure that current scientific information, skills, and activities are publicly accessible and serve ongoing needs as identified by local communities. These funds are being administered by the Alaska Department of Fish and Game.BSEE Herder/BurnerThis is a Joint Industry Program that uses funding from OSRI, ExxonMobil, Shell, Bureau of Safety and Environmental Enforcement, and Clean Caribbean Americas for the development of new oil spill response technology. A remotely operated surface vessel is being developed that can apply chemical herders and ignite herded slicks for in-situ burns. The system will carry remote sensing capabilities and can be controlled locally or through a satellite link.AOOS - Alaska Ocean Observing SystemThis project, funded by NOAA via the Alaska Ocean Observing System, continues implementation of the Prince William Sound (PWS) Observing System (PWSOS). The PWSOS collects ocean, atmospheric and biological observations for use by stakeholders. PWSOS supported tracking of marine organisms using the passive acoustic Ocean Tracking Network, salinity measurements at the Cordova tide station, and the maintenance of the SNOTEL meteorological stations. AOOS Intuitive model-driven particle tracking toolsA team of researchers is developing a particle tracking tool that can be overlayed on oceanographic circulation models to allow users to visualize trajectories of drifters, disabled ships, oil spills, and larvae. The focus is connecting the tools to the Cook Inlet Operational Forecast System model used by NOAA.AKSSF Run timing, spawning distribution, and survival of Copper River sockeyeThe Alaska Sustainable Salmon Fund provided support to radio tag sockeye salmon traveling up the Copper River. The tags were detected at towers along the river and using aerial surveys. The aerial surveys allowed the determination of the final spawning grounds based on the time the fish entered the system and were tagged.NPRB - Automation of Sockeye Salmon Scale EstimationThis project examines the ability of using machine vision and deep learning to automate the reading of Sockeye Salmon scales to determine their age. Automation has the potential to improve management of salmon fisheries. Precise age information is critical to the evaluation of escapement goals, the generation of pre-season forecasts, and the long-term monitoring of population structure.NPRB Seabird use of spatially-predictable tidal ripsThis project adds a bird and mammal component to a physical oceanography project that is separately sponsored by BOEM. The purpose is to discover if birds and mammals are preferentially using tide rips in Cook Inlet. By understanding how birds and mammals use oceanographic features we can better predict potential impacts of oil spills.NOAA Climate adaptation and resilienceThis project addresses the critical need for fishing communities in the Gulf of Alaska to formalize fisheries resilience strategies in adaptation plans, focusing on three of the most highly dependent and divers fishing communities in the region Cordova, Kodiak, and Sitka. The project will advance integrated scientific research and build partnerships between scientists, fishermen, Tribes, and Tribal citizens to enhance local planning capacity and responsiveness to climate change.BOEM Cook Inlet Physical OceanographyWith support from the Bureau of Ocean and Energy Management this project is pulling together the existing data from Cook Inlet, modeling factors that affect circulation, and make field measurements as needed to fill gaps identified in the analysis of the existing data.NPS Examining the health metrics of sockeye salmonThis project supports a UAF led project. It collects tissue samples and energetics estimates from Copper River sockeye salmon. In collaboration with UAF it helps to analyze the data and supports energetic modeling efforts.USFWS Aleutian TernThe Aleutian Tern Technical Committee working group is undertaking a project to determine the current distribution and abundance of Aleutian terns at a statewide scale. This project uses aerial surveys to identify current breeding colonies, and on-the-ground access to estimate tern abundance.PSMFC Empowering coastal Alaska by building local capacity for kelp farmingThis project strives to increase seaweed mariculture success by addressing market development, science-backed information on best practices, and local capacity in collaboration with local mariculture farms and biologists. There is a focus on best practices for collecting and growth of seed stock.EDA Seaweed nursery expansionThis program provides equipment needed to allow PWSSC serve as a nursery facility for local seaweed mariculture operations.EPA Drying SeaweedThis program provided funding to support a proof of concept project to dry seaweed using waste heat. The project would also build community resilience for food security and economic diversity in PWS, AK.NPRB Zooplankton WorkshopFunding to support travel, facility costs, and other meeting costs associated with the Zooplankton Workshop. SEC/AMC - Kelp Seed This project will be conducted in Cordova and Kodiak and provide a comparison of the genetic diversity of bull kelp populations in two important regions for Alaskan kelp farming. The results of this project will clarify 1) whether alternative seeding methods better preserve the genetic diversity of Alaskan kelps and 2) whether alternative seeding methods have the potential to increase the quality of cultured seaweeds.USGS Aerial SurveyAerial survey validation in conjunction with the Prince William Sound Science Center Herring Research and Monitoring Program. This involves working from a vessel while a spotter pilot in an airplane directs (via radio) the vessel to a school of fish, then deploying fishing gear to sample fish in the school.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.
