            -              Overview           

The U.S. Geological Survey provides integrated science that helps formulate, implement, and assess the effectiveness of conservation and restoration actions in the Chesapeake Bay and its watershed. The success of the USGS Chesapeake Bay science studies depends on the coordination of multiple USGS programs, science centers, scientists, and partners.
