Pensacola Mountains
The Pensacola Mountains are a large group of mountain ranges of the Transantarctic Mountains System, located in the Queen Elizabeth Land region of Antarctica. Geography They extend 450 km (280 mi) in a NE-SW direction. Subranges of the Pensacola Mountains include: Argentina Range, Forrestal Range, Dufek Massif, Cordiner Peaks, Neptune Range, Patuxent Range, Rambo Nunataks and Pecora Escarpment. These mountain units lie astride the extensive Foundation Ice Stream and Support Force Glacier which drain northward to the Ronne Ice Shelf. ;Naming Discovered and photographed on 13 January 1956 in the course of a transcontinental nonstop plane flight by personnel of United States Navy Operation Deep Freeze I from McMurdo Sound to Weddell Sea and return. Named by US-ACAN for the U.S. Naval Air Station, Pensacola, Florida, in commemoration of the historic role of that establishment in training aviators of the U.S. Navy. The mountains were mapped in detail by USGS from surveys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forrestal Range
The Forrestal Range () is a largely snow-covered mountain range, about 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. Named by the US-ACAN after , first supercarrier of the U.S. Navy. The entire Pensacola Mountains were mapped by USGS in 1967 and 1968 from U.S. Navy tricamera aerial photographs taken in 1964. Key mountains * Abele Spur () is a rock spur that descends west from Mount Lechner toward the Herring Nunataks. It was named by US-ACAN at the suggestion of Arthur B. Ford for Gunars Abele, civil engineer on the 1973–1974 United States Antarctic Research Program (USARP)-CRREL survey in this area. * Blount Nunatak () is a prominent nunatak, , standing southwest of Mount Lechner on the west side of Forrestal Range.

Operation Deep Freeze
Operation Deep Freeze (OpDFrz or ODF) is codename 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 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 United States military. Task Force 199 was involved. Prior to International Geophysical Year The U.S. Navy already had a record of earlier exploration in Antarctica. As early as 1839, Captain Charles Wilkes led the first U.S. Naval expedition into Antarctic waters. In 1929, Admiral Richard E. Byrd established a naval base at Little America I, led an expedition to explore further inland, and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McMurdo Sound
McMurdo Sound is a sound in Antarctica. It is the southernmost navigable body of water in the world, and is about from the South Pole. Captain James Clark Ross discovered the sound in February 1841, and named it after Lt. Archibald McMurdo of HMS ''Terror''. The sound today serves as a resupply route for cargo ships and for airplanes that land on the floating ice airstrips near McMurdo Station. Physical characteristics Wildlife in the sound include killer whales, seals, Adélie penguins, and emperor penguins. 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 McMurdo Ice Shelf (itself part of the Ross Ice Shelf) by the Haskell Strait. Winter Quarters Bay lies at the south end of the Sound, and is the s ...

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 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 Weddell Sea has been deemed by ...

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] |
Support Force Glacier
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. Mapped by the United States Geological Survey from surveys and US Navy air photos, 1956–66. Named by US-ACAN for the U.S. Naval Support Force Antarctica, which provided logistical support for the United States Antarctic Program during this period.

Median Snowfield
Torbert Escarpment () is an escarpment, long, marking the west margin of Median Snowfield in the Neptune Range, Pensacola Mountains, Antarctica. Mapping and name The Torbert Escarpment was mapped by 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) after Mount Torbert, the salient feature along its edge. Location The Torbert Escarpment faces west in the northeast of the Neptune Range. It runs roughly north–south between the Median Snowfield to the east, and the north end of the Washington Escarpment to the west. Festures include, from south to north, Rivas Peaks, Mount Torbert and Ramsey Cliff. Nearby features to the east include Kaminski Nunatak, Loren Nunataks and Median Snowfield. Features Features and nearby features include: Kaminski Nunatak . A cone-shaped nunatak southeast of Rivas Peaks. Named by US-ACAN for Francis Kaminski ...

Chambers Glacier
Chambers Glacier () is a glacier in the Forrestal Range of the Pensacola Mountains, draining east from Mount Lechner and Kent Gap, at the juncture of Saratoga Table and Lexington Table, to enter Support Force Glacier. It was discovered and photographed on January 13, 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. It was named by the Advisory Committee on Antarctic Names after Captain Washington I. Chambers, U.S. Navy, one of the pioneers in the development of the airplane catapult for ships.
