Abbot Ice Shelf

The Abbot Ice Shelf (72°45′S 96°00′W) is an ice shelf 250 nautical miles (460 km; 290 mi) long and 40 nautical miles (74 km; 46 mi) wide, bordering Eights Coast from Cape Waite to Pfrogner Point in Antarctica. Thurston Island lies along the northern edge of the western half of this ice shelf; other sizable islands (Sherman Island, Carpenter Island, Dustin Island, Johnson Island, McNamara Island, Farwell Island and Dendtler Island) lie partly or wholly within this shelf.

The Abbott Ice Shelf extends to the south of Thurston Island, Dustin Island, McNamara Island, and Farwell Island all of which lie between the ice shelf and the Bellingshausen Sea. It occupies the whole of Peacock Sound in its western part. The Demas Ice Tongue extends into the Amundsen Sea from the west end of the ice shelf. Islands embedded in the Abbott Ice Shelf include the Trice Islands, Sherman Island, Carpenter Island, Johnson Island, Lepley Nunatak and Dendtler Island. It is to the north of King Peninsula and Jones Mountains on the Eights Coast, Cape Waite on King Peninsula lies at its western end, and Pfrogner Point on Fletcher Peninsula is at its eastern end. Fletcher Peninsula separates it from the Venable Ice Shelf to the east.

The Abbot Ice Shelf shelf was sighted by members of the United States Antarctic Service in flights from the ship Bear, in February 1940. Its western portion was delineated from air photos taken by the United States Navy (USN) Operation Highjump, 1946–47. The full extent was mapped by the United States Geological Survey (USGS) from USN air photos of 1966. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Rear Admiral James Lloyd Abbot Jr., Commanding Officer, U.S. Naval Support Force, Antarctica, February 1967 to June 1969.
