Hercules Inlet
Hercules Inlet is a large, narrow, ice-filled inlet which forms a part of the southwestern margin of the Ronne Ice Shelf. It is bounded on the west by the south-eastern flank of the Heritage Range, and on the north by Skytrain Ice Rise. Hercules Inlet marks the southern end of Zumberge Coast and the northwestern end of Queen Elizabeth Land. The inlet was named by the Advisory Committee on Antarctic Names for the LC-130 Hercules aircraft used by the U.S. Naval Support Force, Antarctica, as a photographic and load carrying plane. Hercules Inlet is one of the common starting points for long distance expeditions to the South Pole, taking anywhere from 25 to 81 days. The first expedition from Hercules Inlet to the South Pole took place in 1998, led by Martyn Williams. This 50-day expedition opened up the doorway for South Pole overland journeys, and has become the classic route for most expeditions. The slopes south of the inlet area are covered in crevasse fields, making travel ... [...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, which is the largest of the 14 British Overseas Territories. 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#Past name usage, Edith Ronne Land in 1947–68 and includes areas claimed by the United Kingdom, Chile and Argentina.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heritage Range
The Heritage Range is a major mountain range, long and wide, situated southward of Minnesota Glacier and forming the southern half of the Ellsworth Mountains in Antarctica. The range is complex, consisting of scattered ridges and peaks of moderate height, escarpments, hills and nunataks, with the various units of relief set off by numerous intervening glaciers. The northern portion of the range was probably first sighted by Lincoln Ellsworth in the course of his trans-Antarctic flight of November 23, 1935. On December 14, 1959, the southern range was seen for the first time in a reconnaissance flight from Byrd Station, made by Edward C. Thiel, J. C. Craddock and E. S. Robinson. The team landed at a glacier on Pipe Peak, in the northwestern part of the range, on December 26.Gerald F.

Skytrain Ice Rise
Skytrain Ice Rise () is a large, flattish, peninsula-like ice rise of about 50 miles extent, extending from the vicinity of Meyer Hills in the Heritage Range eastward into the Ronne Ice Shelf of Antarctica. It was mapped by United States Geological Survey (USGS) from surveys and USN air photos, 1961–66, and named by the Advisory Committee on Antarctic Names (US-ACAN) after the LC-47 Douglas Skytrain airplane (also called R4D and Dakota), used extensively in the supply and placement of U.S. field personnel in Antarctica beginning with USN Operation Highjump, 1946–47, and continuing into the late 1960s. See also *Korff Ice Rise Korff Ice Rise is an ice rise, long and wide, lying east-northeast of Skytrain Ice Rise in the southwestern part of the Ronne Ice Shelf, Antarctica.

Zumberge Coast
Zumberge Coast is that portion of the southeast coast of Palmer Land between Cape Zumberge and the south entrance point to Hercules Inlet. Overlooking the west part of Ronne Ice Shelf, this coast was mapped by United States Geological Survey (USGS) from U.S. Navy aerial photographs taken 1961-66 and Landsat imagery taken 1973–74. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1986 after James Zumberge (1923-92), American geologist and glaciologist who directed research on Ross Ice Shelf The Ross Ice Shelf is the largest ice shelf of Antarctica (, an area of roughly and about across: about the size of France).

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] |
LC-130 Hercules
The Lockheed LC-130 is a ski-equipped United States Air Force variant of the C-130 Hercules used in the Arctic and Antarctic. Ten are currently in service with the 109th Airlift Wing of the New York Air National Guard. Design and development The LC-130 started as a prototype model developed by modifying a ''C-130A'' with skis in 1956. After testing in 1957, 12 additional C-130A models were modified with skis and hydraulics under the designation of ''C-130D''. In 1959 the first four factory equipped, ski-based Hercules were produced under the Navy designation of UV-1L. These C-130s are USAF C-130B models. Later in the program the designation was changed from UV-1L to C-130BL. This designation was again later changed to LC-130F when aircraft nomenclature was standardized for all services by the U. S. Defense Department in 1962. These four aircraft were bought by the Navy Department to support the Navy's Antarctic expedition that was ongoing at the time. The Navy also bought one ...

Inlets Of Antarctica
An inlet is a (usually long and narrow) indentation of a shoreline, such as a small arm, bay, sound, fjord, lagoon or marsh, that leads to an enclosed larger body of water such as a lake, estuary, gulf or marginal sea. Overview In marine geography, the term "inlet" usually refers to either the actual channel between an enclosed bay and the open ocean and is often called an "entrance", or a significant recession in the shore of a sea, lake or large river. A certain kind of inlet created by past glaciation is a fjord, typically but not always in mountainous coastlines and also in montane lakes. Multi-arm complexes of large inlets or fjords may be called sounds, e.g., Puget Sound, Howe Sound, Karmsund (''sund'' is Scandinavian for "sound"). Some fjord-type inlets are called canals, e.g., Portland Canal, Lynn Canal, Hood Canal, and some are channels, e.g., Dean Channel and Douglas Channel. Tidal amplitude, wave intensity, and wave direction are all factors that influ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
