Life at the Estuary: Exploring the Vital Role of Freshwater and Ocean Interactions

Estuaries are vital ecosystems where freshwater meets the sea, offering recreational opportunities and serving as crucial habitats for marine life. They protect coastlines from storms and are essential for the health of marine ecosystems. NOAA collaborates with states to manage 28 estuarine reserves, which serve as research sites and educational resources. These reserves help scientists study environmental changes and provide insights for maintaining healthy estuaries. Notable reserves include Chesapeake Bay, Ace Basin, and San Francisco Bay.
