## Definition

a large area of water on the East Coast of the United States where the ocean meets several rivers. It is famous for its seafood, especially crabs and oysters.

For teachers: the largest estuary in the United States, located between Maryland and Virginia. When used as a proper name, it refers specifically to this geographic feature or the surrounding bay region.

## Examples

- We spent the weekend sailing on the Chesapeake.
- The health of the Chesapeake has improved recently due to stricter regulations on industrial runoff and overfishing.
- Ecologists monitor the Chesapeake closely, as its brackish waters support a delicate balance of marine life that is highly sensitive to changes in salinity and temperature.

## Usage notes

- Usually preceded by the definite article 'the' when referring to the bay; often functions as a modifier in compound nouns like 'Chesapeake Bay'.
