The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica.
The South Orkney Islands are a group of islands in the Southern Ocean, about 604 km (375 mi) north-east of the tip of the Antarctic Peninsula and 844 km (524 mi) south-west of South Georgia Island. They have a total area of about 620 km2 (240 sq mi). The islands are claimed both by Britain, and by Argentina as part of Argentine Antarctica. Under the 1959 Antarctic Treaty, sovereignty claims are held in abeyance.
Coats Land is a region in Antarctica which lies westward of Queen Maud Land and forms the eastern shore of the Weddell Sea, extending in a general northeast–southwest direction between 20°00′W and 36°00′W. The northeast part was discovered from the Scotia by William S. Bruce, leader of the Scottish National Antarctic Expedition, 1902-1904. He gave the name Coats Land for James Coats, Jr., and Major Andrew Coats, the two chief supporters of the expedition.
The Forrestal Range is a largely snow-covered mountain range, about 105 km (65 mi) long, standing east of Dufek Massif and the Neptune Range in the Pensacola Mountains of Antarctica. Discovered and photographed on 13 January 1956 on a transcontinental patrol plane flight of U.S. Navy Operation Deep Freeze I from McMurdo Sound to the vicinity of the Weddell Sea and return.
The Neptune Range is a mountain range, 112 km (70 mi) long, lying WSW of Forrestal Range in the central part of the Pensacola Mountains in Antarctica. The range is composed of Washington Escarpment with its associated ridges, valleys and peaks, the Iroquois Plateau, and the Schmidt and Williams Hills. It was discovered and photographed on 13 January 1956 on a US Navy transcontinental plane flight from McMurdo Sound to Weddell Sea and return.
The Patuxent Range or macizo Armada Argentina is a major range of the Pensacola Mountains, comprising the Thomas Hills, Anderson Hills, Mackin Table and various nunataks and ridges bounded by the Foundation Ice Stream, Academy Glacier and the Patuxent Ice Stream. Discovered and partially photographed on January 13, 1956 in the course of a transcontinental nonstop plane flight by personnel of U.S. Navy Operation Deep Freeze I from McMurdo Sound to Weddell Sea and return.
Veststraumen Glacier is a glacier about 45 miles long draining west along the south end of Kraul Mountains into Riiser-Larsen Ice Shelf. The glacier was seen in the course of a U.S. Navy LC-130 plane flight over the coast on November 5, 1967, and was plotted by the United States Geological Survey (USGS) from photographs obtained at that time. In 1969, the Advisory Committee on Antarctic Names (US-ACAN) gave the name "Endurance Glacier" to this feature, but that naming was rescinded because UK Antarctic Place-Names Committee (UK-APC) gave the identical name to a small glacier on Elephant Island. The descriptive name "Veststraumen" appears on a 1972 Norsk Polarinstitutt map.
The Stancomb-Wills Glacier is a large glacier that debouches into the eastern Weddell Sea southward of Lyddan Island. The glacier was discovered in the course of the U.S. Navy LC-130 plane flight over the coast on November 5, 1967, and was plotted by the United States Geological Survey (USGS) from photographs obtained at that time. The name was applied by the Advisory Committee on Antarctic Names (US-ACAN) in 1969.
Weddell Glacier is a glacier 2 nautical miles (3.7 km) long on the north side of South Georgia, flowing north into Royal Bay between Will Point and Cape Charlotte. First mapped by the German group of the International Polar Year Investigations, 1882–83, and named for James Weddell, Master, Royal Navy, who as a sealing captain visited South Georgia in 1823.
Akademik Federov Canyon is an undersea canyon in the Weddell Sea named for the Russian research vessel that worked in the northern Weddell Sea (1989). Dr. Heinrich Hinze of the Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany, proposed the name, which was approved in June 1997.
The Weddell Gyre is one of the two gyres that exist within the Southern Ocean. The gyre is formed by interactions between the Antarctic Circumpolar Current (ACC) and the Antarctic Continental Shelf. The gyre is located in the Weddell Sea, and rotates clockwise. South of the ACC and spreading northeast from the Antarctic Peninsula, the gyre is an extended large cyclone. Where the northeastern end ends at 30°E, which is marked by the southward turn of the ACC, the northern part of the gyre spreads over the Southern Scotia Sea and goes northward to the South Sandwich Arc. Axis of the gyre is over the southern flanks of the South Scotia, America-Antarctic, and Southwest Indian Ridges. In the southern part of the gyre, the westward return flow is about 66 sverdrup (Sv), while in the northern rim current, there is an eastward flow of 61 Sv.
Amundsen Plain is an undersea abyssal plain named in association with Amundsen Coast. The name was approved by the Advisory Committee on Undersea Features in June 1988.
Boyd Strait is the 40-kilometre (25 mi) wide strait lying between Snow Island and Smith Island in the South Shetland Islands, Antarctica, and linking Drake Passage and the Bransfield Strait.
King Haakon VII Sea is a proposed name for part of the Southern Ocean on the coast of East Antarctica.
Cline Glacier is a large glacier that drains the vicinity at the east side of Mount Jackson and flows generally southeast between Schirmacher Massif and Rowley Massif into the head of Odom Inlet, on the east side of Palmer Land. It was mapped by United States Geological Survey in 1974, and named by the Advisory Committee on Antarctic Names for David R. Cline, United States Antarctic Research Program biologist on the International Weddell Sea Oceanographic Expeditions in 1968 and 1969.
Cape Fairweather is a cape in Antarctica that is 705 metres (2,310 ft) high and is ice-covered except for rocky exposures along its southeast and east sides. It lies midway between Drygalski Glacier and Evans Glacier on the east coast of Graham Land and divides Nordenskjöld Coast from Oscar II Coast. Rogosh Glacier branches at the ridge forming Cape Fairweather and flows into Artanes Bay to the south, and into Weddell Sea west of Pedersen Nunatak to the east. The cape was charted in 1947 by the Falkland Islands Dependencies Survey, which named it for Alexander Fairweather, captain of the Dundee whaler Balaena, which operated along the northeast coast of the Antarctic Peninsula in 1892–1893.
Gould Bay is a bay located at the junction of the Filchner Ice Shelf with the northeast corner of Berkner Island, in the southern Weddell Sea. It was discovered by the Ronne Antarctic Research Expedition, 1947–48, under the leadership of Commander Finn Ronne, U.S. Navy Reserve, who named this bay for Laurence M. Gould, geologist, geographer, and second in command of the Byrd Antarctic Expedition, 1928–30.
Helmert Bank is a submarine bank in the Weddell Sea named for the German geodesist Friedrich Robert Helmert. The name was proposed by Dr. Heinrich Hinze of the Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany, and was approved by the Advisory Committee for Undersea Features in June 1997.
The Hofmann Trough is a submarine bank in the Weddell Sea. It is named for Walther Hofmann (1920–1993), a cartographer/photogrammetrist on polar expeditions. The name was proposed by Heinrich Hinze of the Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany, and was approved by the Advisory Committee for Undersea Features in June 1997.
