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.
