[′tīd·əl ′märsh]Tidal Marsh
(in Russian, vatty, from German Watten and Dutch wadden: “coastal spits”), a part of a flat, low-lying seacoast, covered daily the the sea during high tide and free of sea water during ebb tide. The surface of a tidal marsh is characterized by a branched network of tidal and river water troughs that frequently change their position. Tidal marshes are found on the southern coasts of the North Sea as well as along the coasts of the White Sea, the Barents Sea, the Sea of Okhotsk, the Bering Sea, the Gulf of Mexico, and others.
