Description:
The goal of this project is to develop and test a new approach to examine the degree to which methods used for mitigation and remediation of wetland and estuarine sediments reduce the transfer of contaminants to the environment. We will compare and contrast three proposed mitigation strategies: capping, phytoremediation, and marsh restoration using contaminated sediments.

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.
