Chesapeake Bay Activities

Home

The Chesapeake Bay is our Nation’s largest estuary and provides over $100 billion in annual economic value. The USGS works with Federal, State, local, and academic partners to provide research and monitoring and to communicate results to inform management for the Chesapeake and other important landscapes across the Nation. See our Science page to learn about our themes and topics being addressed.
