The main distinguishing feature from other middle ridges is a large width, less dissected and less pronounced rift zone . In the structure, the zone of through faults and associated gorges play an important role, which cut the ridge into separate segments and provide free penetration of cold bottom waters from the south into the basins located to the north.
