Lomonosov Ridge


an underwater ridge in the Arctic Ocean. It extends for about 1,800 km from the Novosibirskie Islands across the central part of the ocean to Ellesmere Island in the Canadian arctic archipelago. It is 60-200 km wide and rises 3,300-3,700 m from the ocean floor. At its greatest height the ridge lies at a depth of 954 m. The relatively steep slopes are dissected by canyons and covered by a layer of sandy silt. It was discovered in 1948 by Soviet polar expeditions and named in honor of M. V. Lomonosov.
