Abstract:

This project will continue physical and biological measurements to assess trends in the marine environment and bottom-up impacts on the marine ecosystems of Prince William Sound (PWS). Regular (~6 per year) vessel-based surveys of PWS will be conducted to maintain ongoing time series observations of physical (temperature, salinity, turbidity), biogeochemical (nitrate, phosphate, silicate, dissolved oxygen), and biological (chlorophyll-a concentration, zooplankton abundance and composition) parameters in several parts of PWS. Sampling sites include central PWS, the entrances (Hinchinbrook Entrance and Montague Strait), and four priority bays that were part of the Exxon Valdez Oil Spill Trustee Council- (EVOSTC)-funded Sound Ecosystem Assessment (SEA) project in the 1990s and the ongoing Herring Research and Monitoring project. Additionally, an autonomous profiling mooring will be deployed each year in central PWS to provide high frequency (at least daily) depth-specific measurements of the surface layer that will be telemetered out in near real-time. The profiler will include measurements that complement the survey activities (temperature, salinity, oxygen, nitrate, chlorophyll-a, turbidity). An in situ plankton camera is under development and will be used to enumerate zooplankton, large phytoplankton and other particles, with some taxonomic discrimination. FY17 spring and early summer observations in PWS indicate the spring bloom was about on time, the surface layer water temperature was 1-2 °C above average, but still showing negative anomalies below the surface layer. Some warm water zooplankton (southern species) are still present. We are not proposing any major changes to this project for FY18.
