Berkner Island (also known as the Berkner Ice Rise or as Hubley Island) is an Antarctic ice rise, where bedrock below sea level has caused the surrounding ice sheet to create a dome. If the ice cap were removed, the island would be underwater.[1] Berkner Island is completely ice-covered and is about 320 kilometres (200 mi) long and 150 kilometres (93 mi) wide, with an area of 44,000 km2 (17,000 sq mi). It is surrounded by the Filchner-Ronne Ice Shelf. The northernmost point of the Berkner is about 20 kilometres (12 mi) from the open sea. It lies in the overlapping portion of the Argentine and the British Antarctic territorial claims.
The island rises to 869 m (2,850 ft) (975 m or 3,200 ft, according to other sources) and separates the Ronne Ice Shelf from the Filchner Ice Shelf. It is characterized by two domes, Reinwarthhöhe in the north (698 m or 2,290 ft), and Thyssenhöhe in the south (869 m or 2,851 ft). It is indented by three bays on the eastern side, which are, from north to south, the McCarthy Inlet, the Roberts Inlet, and the Spilhaus Inlet. The southern tip is named the Mulvaney Promontory. Gould Bay is on the north coast. Berkner Island is about 150 km (93 mi) west of Luitpold Coast, Coats Land, the closest mainland of Eastern Antarctica. The Hemmen Ice Rise is 17 km (10.6 mi) off the northwest corner of Berkner Island.
