linear sand ridge A submarine sand mound, typical of shallow sea and wide continental-shelf areas, 3–10 m high, 1–2 km wide, which may extend for tens of kilometres across the shelf. Individual ridges have an average spacing of about 3 km. Such ridges have been described from the North Sea (off Norfolk, England) and the eastern seaboard of the USA. They are the product of storm and tidal action.
