|a large arm of the S Pacific in Antarctica, incorporating the Ross Ice Shelf and lying between Victoria Land and the Edward VII Peninsula|
southern extension of the Pacific Ocean, which, along with the vast ice shelf (see Ross Ice Shelf) at its head, makes a deep indentation in the circular continental outline of Antarctica. The sea is a generally shallow marine region, approximately 370,000 sq mi (960,000 sq km) in area, centred at about 75 S, 175 W, and lying between Cape Adare in northern Victoria Land on the west and Cape Colbeck on Edward VII Peninsula on the east. The northern limit lies approximately along the edge of the continental shelf and the southern limit along a great barrier wall of ice marking the front of the Ross Ice Shelf.
