Amundsen Plain ( 65°0′S125°0′W / 65.000°S 125.000°W ) 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.
The Wisconsin Range is a major mountain range of the Horlick Mountains in Antarctica, comprising the Wisconsin Plateau and numerous glaciers, ridges and peaks bounded by the Reedy Glacier, Shimizu Ice Stream, Horlick Ice Stream and the interior ice plateau.
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.
Amundsen Glacier is a major Antarctic glacier, about 7 to 11 km wide and 150 km (80 nmi) long, originating on the polar plateau where it drains the area to the south and west of Nilsen Plateau, and descending through the Queen Maud Mountains to enter the Ross Ice Shelf just west of the MacDonald Nunataks. The tributary Blackwall Glacier flows northwest along the northeast side of Hansen Spur to join Amundsen Glacier.
Smith Glacier is a low-gradient Antarctic glacier, over 160 km (100 mi) long, draining from Toney Mountain in an ENE direction to Amundsen Sea. A northern distributary, Kohler Glacier, drains to Dotson Ice Shelf but the main flow passes to the sea between Bear Peninsula and Mount Murphy, terminating at Crosson Ice Shelf.
The Isle of Man to England Interconnector is a submarine power cable connecting the transmission system of the Manx Utilities Authority to that of Great Britain. With an undersea section of approximately 104 km, it is the second longest AC undersea cable in the world.
The Bellingshausen Sea is an area along the west side of the Antarctic Peninsula between 57°18'W and 102°20'W, west of Alexander Island, east of Cape Flying Fish on Thurston Island, and south of Peter I Island. In the south are, from west to east, Eights Coast, Bryan Coast and English Coast of West Antarctica. To the west of Cape Flying Fish it joins the Amundsen Sea.
Cape Flying Fish is an ice-covered cape which forms the western extremity of Thurston Island. It was discovered by Richard E. Byrd and members of the US Antarctic Program in a flight from the USS Bear in February 1940. It was named by the Advisory Committee on Antarctic Names for the United States Exploring Expedition ship USS Flying Fish, commanded by William M. Walker, which reached a point within 125 miles of this cape; the ship's position on the morning of March 23, 1839, was 70°0′S100°16′W.
Sulzberger Bay is a bay between Fisher Island and Vollmer Island, along the coast of King Edward VII Land. Discovered by the Byrd Antarctic Expedition on December 5, 1929, and named by Byrd for Arthur H. Sulzberger, publisher of The New York Times, a supporter of the Byrd expeditions in 1928–1930 and 1933–1935.
Devils Glacier is a heavily crevassed glacier at the edge of the polar plateau, about 20 nautical miles long and 8 nautical miles wide, draining the southern part of the Mohn Basin and flowing northeast to enter the upper part of Amundsen Glacier just north of the mountain group consisting of Mounts Wisting, Hassel, Bjaaland and Prestrud.
Adélie Valley, also variously known as Adilie Valley, Dumont d'Urville Trough or Adélie Trough, is a drowned fjord on the continental margin of East Antarctica. Named in association with this long named portion of Wilkes Land on the Antarctic coast. Name approved by the Advisory Committee on Undersea Features in December 1971.
The Lazarev Trough is an undersea trough off the coast of Antarctica. It was named for the Russian polar explorer Admiral Mikhail P. Lazarev, commanding officer of the sloop Mirnyy during the Bellingshausen expedition of 1819–1821. The name, proposed by G. Agapova of the Geological Institute of the Russian Academy of Sciences, was approved by the Advisory Committee for Undersea Features in August 1985.
Bellingshausen Plain, also known as Bellinghausen Abyssal Plain, is an undersea plain parallel to the continental rise in the Bellingshausen Sea, named for Admiral Fabian Gottlieb von Bellingshausen, commander of the Russian Antarctic Expedition (1818–1821). The name was approved by the Advisory Committee for Undersea Features in April 1974.
Amundsen Coast is that portion of the coast to the south of the Ross Ice Shelf lying between Morris Peak, on the east side of Liv Glacier, and the west side of the Scott Glacier. Named by New Zealand Antarctic Place-Names Committee in 1961 for Captain Roald Amundsen, the Norwegian explorer who led his own expedition in 1910–12 to the Antarctic. Setting up a base at Framheim at the edge of the Ross Ice Shelf, he sledged southward across the shelf and discovered a route up the Axel Heiberg Glacier along this coast to reach the polar plateau. He was the first to reach the South Pole, December 14, 1911.
Weddell Plain is an undersea abyssal plain named in association with the Weddell Sea. Name approved 6/87.
Norway Glacier is an Antarctic tributary glacier about 10 nautical miles (18 km) long, descending the polar plateau just west of Mount Prestrud, and flowing northeast to enter Amundsen Glacier between Mount Bjaaland and Mount Hassel, in the Queen Maud Mountains. Named by Advisory Committee on Antarctic Names (US-ACAN) in association with the many features named in this area for members of Amundsen's Norwegian expedition of 1910–12.
Nilsen Plateau is a rugged, ice-covered plateau in Antarctica. When including Fram Mesa, the plateau is about 30 nautical miles (60 km) long and 1 to 12 nautical miles (22 km) wide, rising to 3,940 m between the upper reaches of the Amundsen and Scott Glaciers, in the Queen Maud Mountains. Discovered in November 1911 by the Norwegian expedition under Roald Amundsen, and named by him for Captain Thorvald Nilsen, commander of the ship Fram. The highest peak in Nilsen Plateau is unnamed and has an elevation of 3940 metres.
Epler Glacier is a tributary glacier, 10 nautical miles long, draining west from Nilsen Plateau in the Queen Maud Mountains to enter Amundsen Glacier just south of the Olsen Crags. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–64, and was named by the Advisory Committee on Antarctic Names for Charles F. Epler, a storekeeper with U.S. Navy Squadron VX-6 on Operation Deep Freeze 1966 and 1967.
Moffett Glacier is a tributary glacier, 13 nautical miles (24 km) long, flowing east from Rawson Plateau to enter Amundsen Glacier just south of Mount Benjamin, in the Queen Maud Mountains of Antarctica. it was discovered by Rear Admiral Richard E. Byrd on the South Pole flight of November 28–29, 1929, and named by him for Rear Admiral William A. Moffett, U.S. Navy, first Chief of the Bureau of Aeronautics, Department of the Navy.
Lecointe Guyot is an undersea tablemount located about 430 km north-northwest of Peter I Island in the Southern Ocean. It is named for Georges Lecointe, navigator/astronomer aboard the Belgica. The name was proposed by Dr. Rick Hagen 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 minimal depth is 280m.
Charcot Fan is a deep-sea formation in the Southern Ocean. It lies off the coast of the West Antarctic Ellsworth Land.
