Do Oyster Filtration and Wave Attenuation Associated with Oyster Reefs and Breakwater Improve Seagrass Habitat?

Principal Investigator:

Raleigh Hood

Start/End Year:

2003 - 2006

Institution:

Horn Point Laboratory, University of Maryland Center for Environmental Science

Co-Principal Investigator:

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.
