West Antarctic Rift

West Antarctic Rift System
The name is most commonly used in the scientific literature, at times along with the West Antarctic Rift System, which is of larger extent and has geologic meaning.
It encompasses the Ross Embayment, the Ross Sea, the area under the Ross Ice Shelf and a part of Marie Byrd Land in West Antarctica, reaching to the base of the Antarctic Peninsula.
