Description:
The objective of this study is to deploy NASA's Ocean Data Acquisition System (ODAS) in the Chesapeake Bay during successive winter-spring transitions in 1990 and 1991 to produce fine-scale maps of phytoplankton biomass. ODAS is an aircraft borne ocean color instrument that is used to detect chlorophyll concentrations. We propose to track event-scale changes in phytoplankton distributions during the diatom blooms that develop annually in the mesohaline to polyhaline part of the Bay.

Featured Fellow
Nina Santos is a Ph.D. student at the Chesapeake Biological Laboratory at the University of Maryland Center for Environmental Science. For her dissertation, she is focused on small shrimp-like crustaceans called mysids – an understudied yet important part of many estuarine and coastal food webs.

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.
