Description:
This research will use ocean color data from satellite and aircraft instruments in data assimilation models to: quantify seasonal and interannual variability of phytoplankton biomass and productivity in the Chesapeake Bay with unprecedented spatial and temporal resolution; use in combination with a coupled biological and physical model of Chesapeake Bay and the outflow plume to interpolate between observational periods, extend these observations in a third - vertical - dimension, and provide estimates of production and biomass of higher trophic levels.

Developing a habitat model for mysids, an important link in Chesapeake Bay food webs
Mysids are important mesozooplankton prey for many species of fish in Chesapeake Bay and are an important link in transferring energy from lower to upper trophic levels. Mysids also serve as biological vectors for benthic-pelagic coupling due to their diel vertical migration and omnivorous prey-switching behavior, which makes mysids important regulators of food web architecture. Despite their central role in coastal food webs, surprisingly little is known about mysid ecology and dynamics in Chesapeake Bay.
