Coastal barrier.

Coastal barrier. A depositional geologic feature that is subject to wave, tidal, and wind energies; protects landward aquatic habitats from direct wave attack; and includes all associated aquatic habitats such as adjacent wetlands, marshes, estuaries, inlets, and nearshore waters. These can include islands; spits of land connected to a mainland at one end; sand bars that connect two headlands and enclose aquatic habitat; broad, sandy, dune beaches; or fringing mangroves. Coastal barriers are found on coastlines including major embayments and the Great Lakes of the United States and its territories.
