Chesapeake Bay Activities

Bibliography of USGS Publications

The USGS has published reports and journal articles on a large number of topics related to the Chesapeake Bay and its watershed. Some recent reports are online. Findings from the publications are used by Chesapeake Bay Program resource managers and policy makers to make science-based decisions for ecosystem conservation and restoration. USGS Chesapeake Bay science information is also critical for the restoration of ecosystems throughout the United States.
