Abstract: This project is a component of the Sound Ecosystem Assessment (SEA) program, a multi-disciplinary effort to acquire an ecosystem level understanding of the marine and freshwater processes that interact to constrain levels of fish, marine bird, and marine mammal production in Prince William Sound (PWS). Pink salmon and herring populations in PWS have been damaged by the EVOS and are not recovering. Populations of harbor seals (predators of salmon and other fishes) are continuing to decline. Primary production is the basis of the food web and subsequent energy transfers are ultimately based on the phytoplankton growth in PWS or phytoplankton imported in the oceanic water mass. No measurement of ambient nutrient conditions of phytoplankton biomass and production has been conducted throughout the EVOS recovery period. This project will provide phytoplankton and nutrient data to examine the temporal and spatial variability in the chemical and primary production fields, and to test the ecological theory that the production of upper trophic level species is modulated by variations in nutrient-driven phytoplankton production. Water samples will be collected for plankton sampling, chlorophyll measurements, and nutrient analysis. Satellite imagery will be used to track PWS water masses, chlorophyll distribution, and sea-surface temperatures.
