Description:
This project addresses one of the priorities established by Maryland Sea Grant: the health of our coastal ecosystems, or more specifically, a physical-biological link between oyster reefs and seagrass habitats. Our objectives are: (1) quantify the impact of oyster reefs and breakwaters on wave attenuation and water clarity using a combination of numerical modeling and field studies; (2) evaluate the potential for oyster reefs to create suitable seagrass habitats using these same approaches; (3) develop a model that can be used by managers to help guide their seagrass and oyster restoration efforts; (4) educate managers and citizens about the importance of oyster reefs in maintaining water quality and seagrass habitat.

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.
