Greenwell Glacier
The Greenwell Glacier is a major tributary glacier, long, draining northwest between the Mirabito Range and the Everett Range to enter Lillie Glacier below Mount Works, in northwest Victoria Land, Antarctica. This geographical feature was first mapped by the United States Geological Survey from surveys and from U.S. Navy aerial photography, 1960–63, and was so named by the Advisory Committee on Antarctic Names for Commander Martin D. Greenwell, U.S. Navy, Commander of Antarctic Squadron Six (VX-6), 1961–62. The glacier lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

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 ...

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ...

Lillie Glacier
Lillie Glacier () is a large glacier in Antarctica, about long and wide. It lies between the Bowers Mountains on the west and the Concord Mountains and Anare Mountains on the east, flowing to Ob' Bay on the coast and forming the Lillie Glacier Tongue. The glacier tongue (), the prominent seaward extension of the glacier into Ob' Bay, was discovered by the British Antarctic Expedition, 1910–13, when the '' Terra Nova'' explored westward of Cape North in February 1911. It was named by the expedition for Dennis G. Lillie, a biologist on the ''Terra Nova''. The name Lillie has since been extended to the entire glacier. The lower half of the glacier was plotted by the Australian National Antarctic Research Expedition (''Thala Dan'') in 1962, which explored the area and utilized air photos taken by U.S. Navy Operation Highjump, 1946–47. The whole feature was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–62. See also * List of glaci ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

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]   |

VX-6
Air Development Squadron Six (VX-6 or AIRDEVRON SIX, commonly referred to by its nickname, "puckered penguins") was a United States Navy Air Development Squadron based at McMurdo Station, Antarctica. Established at Naval Air Station Patuxent River, Maryland on 17 January 1955, the squadron's mission was to conduct operations in support of Operation Deep Freeze, the operational component of the United States Antarctic Program. Using the tail code ''XD'', the squadron flew numerous fixed-wing aircraft and helicopters over the course of its existence—many of which were pioneering endeavors. For example, the first air link between Antarctica and New Zealand was established by men and aircraft of VX-6 in 1955. The following year, a ski-equipped R4D Dakota of VX-6 became the first aircraft to land at the South Pole. In 1961, the first emergency midwinter medical evacuation flight was conducted from Byrd Station to Christchurch. In 1963, an LC-130F Hercules of VX-6 made the longest ...

Pennell Coast
Pennell Coast is that portion of the coast of Antarctica between Cape Williams and Cape Adare. To the west of Cape Williams lies Oates Coast, and to the east and south of Cape Adare lies Borchgrevink Coast. Named by New Zealand Antarctic Place-Names Committee (NZ-APC) in 1961 after Lieutenant Harry Pennell, Royal Navy, commander of the Terra Nova, the expedition ship of the British Antarctic Expedition, 1910–13. Pennell engaged in oceanographic work in the Ross Sea during this period. In February 1911 he sailed along this coast in exploration and an endeavor to land the Northern Party led by Lieutenant Victor Campbell. The name is also used more loosely to refer to both the coast itself and the hinterland extending south to the watershed of the Southern Cross Mountains to the southeast and the Usarp Mountains to the west. Major features of the coast include the 250-kilometer long Rennick Glacier (one of Antarctica's largest glaciers), the Anare Mountains, and the norther ...
