San Martín Glacier
The Support Force Glacier () is a major glacier in the Pensacola Mountains, draining northward between the Forrestal Range and Argentina Range to the Filchner-Ronne Ice Shelf. Mapping and name The Support Force Glacier was mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photographs in 1956–66. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for the United States Naval Support Force Antarctica, which provided logistical support for the United States Antarctic Program during this period. Location The Support Force Glacier flows in a north-northeast direction past the Forrestal Range to its west. It is fed by the Chambers Glacier from the west, which separates the Saratoga Table from the Lexington Table in the Forrestal Range. Further north it passes the Argentina Range to the east. The San Martín Glacier enters from the east, flowing between the Schneider Hills and the Panzarini Hills in this r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen Elizabeth Land
Queen Elizabeth Land is a portion of mainland Antarctica named by the government of the United Kingdom and claimed as part of the British Antarctic Territory. Situated south of Weddell Sea and between longitudes 20°W and 80°W, stretching from Filchner-Ronne Ice Shelf to the South Pole. It is bordered by Zumberge Coast of Ellsworth Land to the West and by Hercules Inlet to the Northwest. To the Northeast, circle of latitude 82°S is the dividing line against Coats Land. The area of Queen Elizabeth Land was unnamed until 2012, though most of it was unofficially known as Edith Ronne Land in 1947–68 and includes areas claimed by the United Kingdom, Chile and Argentina. History On the occasion of a visit by Queen Elizabeth II to the British Foreign and Commonwealth Office in London on 18 December 2012, it was announced there that a area of the British Antarctic Territory had been named Queen Elizabeth Land after The Queen.

Weddell Sea
The Weddell Sea is part of the Southern Ocean and contains the Weddell Gyre. Its land boundaries are defined by the bay formed from the coasts of Coats Land and the Antarctic Peninsula. The easternmost point is Cape Norvegia at Princess Martha Coast, Queen Maud Land. To the east of Cape Norvegia is the King Haakon VII Sea. Much of the southern part of the sea is covered by a permanent, massive ice shelf field, the Filchner-Ronne Ice Shelf. The sea is contained within the two overlapping Antarctic territorial claims of Argentine Antarctica, the British Antarctic Territory, and also resides partially within the Antártica Chilena Province, Antarctic Chilean Territory. At its widest the sea is around across, and its area is around . Various ice shelves, including the Filchner-Ronne Ice Shelf, fringe the Weddell sea. Some of the ice shelves on the east side of the Antarctic Peninsula, which formerly covered roughly of the Weddell Sea, had completely disappeared by 2002. The Weddel ...

McMurdo Sound
The McMurdo Sound is a sound in Antarctica, known as the southernmost passable body of water in the world, located approximately from the South Pole. Captain James Clark Ross discovered the sound in February 1841 and named it after Lieutenant Archibald McMurdo of HMS ''Terror''. The sound serves as a resupply route for cargo ships and airplanes that land on floating ice airstrips near McMurdo Station. The McMurdo seasonal Ice Runway was operated from October to December from the 1950s to the 2010s, then in December the ice breaks up and McMurdo port is opened by an Icebreaker ship and ships can resupply the Antarctic bases. Physical characteristics Boundary and extents The sound extends approximately 55 kilometers (34 mi) in length and width, and opens into the larger Ross Sea to the north. To the south, the sound is bounded by the Ross Ice Shelf cavity, to the west lies the Royal Society Range, and to the east is Ross Island. McMurdo Sound is separated from the ...

Operation Deep Freeze
Operation Deep Freeze is the code name for a series of United States missions to Antarctica, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on. (There was an initial operation before Richard E. Byrd, Admiral Richard Byrd proposed 'Deep Freeze'). Given the continuing and constant US presence in Antarctica since that date, "Operation Deep Freeze" has come to be used as a general term for US operations in that continent, and in particular for the regular missions to resupply US Antarctic bases, coordinated by the Military of the United States, United States military. Task Force 199 was involved. For a few decades the missions were led by the United States Navy, though the Air National Guard and National Science Foundation are also important parts of the missions. In Antarctica, when the polar dawn starts late in the year things begin warming up and the mission usually runs from late in the year to ear ...

Panzarini Hills
The Argentina Range () is a range of rock peaks and bluffs, long, lying east of the northern part of Forrestal Range in the northeastern portion of the Pensacola Mountains of Antarctica. Discovery and name The Argentina Range was discovered and photographed on January 13, 1956, in the course of a United States Navy transcontinental nonstop plane flight from McMurdo Sound to Weddell Sea and return. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) after Argentina, which for many years from 1955 maintained a scientific station on the Filchner Ice Shelf at the General Belgrano or Ellsworth Station site. The entire Pensacola Mountains were mapped by United States Geological Survey (1863) in 1967 and 1968 from ground surveys and from United States Navy tricameral photographs taken in 1964. Location The Argentina Range lies between the Support Force Glacier to the west, which separates it from the Forrestal Range, and the East Antarctic Ice Sheet t ...

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
