Everything about Berkner Island totally explained
Berkner Island or
Berkner Ice Rise or
Hubley Island is a high and completely
ice-covered large
island about 320 km (200
miles) long and 135 km (85
miles) wide in
Antarctica, with an area of 43873.1 km² (16939.42 mi²). It is the second largest island of both Antarctica and the
British Antarctic Territory, after
Alexander Island. Berkner Island is the southernmost island of the world, a title that's sometimes incorrectly awarded to
Ross Island. Berkner Island is however - other than Ross Island - not accessible from the sea, since it's completely surrounded by
ice shelf. The northernmost point of the island is still about 17 km from the open sea.
The island rises to 869 m (975 m or 3,200 ft according to other sources) and separates
Ronne Ice Shelf from the
Filchner Ice Shelf. It is characterized by two domes,
Reinwarthhöhe in the north (698 m), at, and
Thyssenhöhe in the south (869 m), at . Berkner Island is about 150 km west of
Luitpold Coast,
Coats Land, the closest mainland of
Eastern Antarctica. 17 km off the northwest corner of Berkner Island is
Hemmen Ice Rise.
Berkner Island was discovered by members of the United States-
International Geophysical Year (US-IGY) party at
Ellsworth Station under the leadership of Capt.
Finn Ronne,
United States Navy Reserve (USNR), during the
1957-
1958 season. Berkner Island was named by the
United States Advisory Committee on Antarctic Names (US-ACAN) for
American physicist
Lloyd Berkner, engineer with the
Byrd Antarctic Expedition (
1928-
1930).
Since 1990, Berkner Island has been a jumping off point for a number of long distance polar expeditions.
In the 1994/1995 field season the
British Antarctic Survey,
Alfred Wegener Institute and the Forschungsstelle für Physikalische Glaziologie of the
University of Münster cooperated in a project drilling ice cores on the North and South Domes of Berkner Island.
