Project Information

EVOSTC Data Archive: The modeling conducted by this project simulates ocean currents within Prince William Sound as well as the feeding interactions and spatial distribution of certain fish species. The ocean circulation model generates time varying current velocity vectors and salinity and temperature scalers. It is based on a Mellor-Blumberg ocean circulation model and runs with a horizontal spatial resolution of 1.2 kilometer and 11 depth intervals. The biophysical plankton model simulates dynamics in phytoplankton and zooplankton populations in response to physical (winds, light, temperature) forcing. The model is run with actual wind fields, and incorporates two types of phytoplankton and three types of zooplankton. In FY 96 and beyond, this portion of 320J has been moved to 320R. The coupled trophic interaction fish model simulates the spatial distribution of species, foraging interactions, and the resulting juvenile fish growth and mortality. The model uses time varying feeding rates and predator densities and the dependence of these on physical conditions.
