Pickering Nunatak
Pickering Nunatak () is a prominent nunatak at the east side of the mouth of Lambert Glacier, situated 20 nautical miles (37 km) south-southwest of Manning Nunataks. Sighted on a flight by an ANARE ( Australian National Antarctic Research Expeditions) Beaver aircraft over the Amery Ice Shelf on November 2, 1957.

Pickering Nunataks
Pickering Nunataks () is a group of nunataks lying 2 nautical miles (3.7 km) southwest of Mount Phoebe and on the northeast side of Saturn Glacier, near the east coast of Alexander Island, Antarctica. The nunataks were photographed by Lincoln Ellsworth on November 23, 1935, in the course of a trans-Antarctic flight and were plotted from the air photos by W.L.G. Joerg. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) from association with Saturn Glacier after William H. Pickering (1858–1938), the American astronomer who discovered Phoebe, one of the satellites of the planet Saturn, the sixth planet of the Solar System The Solar System Capitalization of the name varies.

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lambert Glacier
Lambert Glacier is a major glacier in East Antarctica. At about 50 miles (80 km) wide, over 250 miles (400 km) long, and about 2,500 m deep, it is the world's largest glacier. It drains 8% of the Antarctic ice sheet to the east and south of the Prince Charles Mountains and flows northward to the Amery Ice Shelf. It flows in part of Lambert Graben and exits the continent at Prydz Bay. This glacier was delineated and named in 1952 by American geographer John H. Roscoe who made a detailed study of this area from aerial photographs taken by Operation Highjump, 1946–47. He gave the name "Baker Three Glacier", using the code name of the Navy photographic aircraft and crew that made three flights in this coastal area in March 1947 resulting in geographic discoveries. The glacier was described in Gazetteer No. 14, ''Geographic Names of Antarctica'' (U.S. Board on Geographic Names, 1956), but the feature did not immediately appear on published maps. As a result the name Lam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manning Nunataks
The Manning Nunataks () are a group of nunataks in the eastern side of the southern part of the Amery Ice Shelf, Antarctica, about north-northeast of Pickering Nunatak. They were photographed from the air by Australian National Antarctic Research Expeditions in 1957, and were named by the Antarctic Names Committee of Australia for Sergeant A.S. Manning, Royal Australian Air Force, an airframe fitter at Mawson Station The Mawson Station, commonly called Mawson, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD).

Australian National Antarctic Research Expeditions
The Australian National Antarctic Research Expeditions (ANARE ) is the historical name for the Australian Antarctic Program (AAp) administered for Australia by the Australian Antarctic Division (AAD). History Australia has had a long involvement in south polar regions since as early as Douglas Mawson's Australasian Antarctic Expedition in 1911. Further Australian exploration of the Antarctic continent was conducted during the British Australian and New Zealand Antarctic Research Expedition (BANZARE), which was conducted over the years 1929–1931. The Australian National Antarctic Research Expeditions were established in 1947 with expeditions to Macquarie Island and Heard Island. In 1948 the Australian Antarctic Division (AAD) was established to administer the expedition program. ANARE Name The name ANARE fell out of official use in the early 2000s. However current and former Australian Antarctic expeditioners continue to use the term informally as a means of identifica ...

Amery Ice Shelf
The Amery Ice Shelf () is a broad ice shelf in Antarctica at the head of Prydz Bay between the Lars Christensen Coast and Ingrid Christensen Coast. It is part of Mac. Robertson Land. The name "Cape Amery" was applied to a coastal angle mapped on 11 February 1931 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Douglas Mawson. He named it for William Bankes Amery, a civil servant who represented the United Kingdom government in Australia (1925–28). The Advisory Committee on Antarctic Names interpreted this feature to be a portion of an ice shelf and, in 1947, applied the name Amery to the whole shelf. In 2001 two holes were drilled through the ice shelf by scientists from the Australian Antarctic Division and specially designed seabed sampling and photographic equipment was lowered to the underlying seabed. By studying the fossil composition of sediment samples recovered, scientists have inferred that a major retreat of the Amery Ice Shelf to ...

Antarctic Names Committee Of Australia
The Australian Antarctic Names and Medals Committee (AANMC) was established to advise the Government on names for features in the Australian Antarctic Territory and the subantarctic territory of Heard Island and the McDonald Islands. The committee also issues nominations Governor General for the award of the Australian Antarctic Medal. Committee members were appointed by the Minister or Parliamentary Secretary responsible for Antarctic matters. The committee was founded in 1952 as the Antarctic Names Committee of Australia, and changed to the current name in 1982 to reflect the multiple functions that the committee is responsible for. The committee was replaced by the Australian Antarctic Division Place names Committee in 2015. Features named by the committee * Fyfe Hills, named after W.V.

Antarctic Flight RAAF
The Antarctic Flight was a Royal Australian Air Force (RAAF) aircraft flight. It operated from RAAF Base Laverton and Mawson Station. The flight was responsible for expeditions and rescue missions in Antarctica. Two ski fitted RAAF Auster AOP.6 (A11-200 & A11-201) were based at Mawson Station from 1952. On 5 March 1954, A11-200 was lost over the side of a ship. Later the flight included two DHC-2 Beavers and one Dakota aircraft. After 1963, the RAAF planes were withdrawn. Following this time RAAF aircraft have continued to operate infrequently in support of activities in the Antarctic and sub-Antarctic islands. These have included a number of flights using C-130 Hercules in the 1970s and 1980s into McMurdo Sound and more recently C-17 Globemasters to Wilkins Aerodrome near Casey Station Casey Station, commonly called Casey, is one of three permanent stations and research outposts in Antarctica managed by the Australian Antarctic Division (AAD).

Mawson Station
The Mawson Station, commonly called Mawson, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Mawson lies in Holme Bay in Mac. Robertson Land, East Antarctica in the Australian Antarctic Territory, a territory claimed by Australia. Established in 1954, Mawson is Australia's oldest Antarctic station and the oldest continuously inhabited Antarctic station south of the Antarctic Circle. Mawson was named in honour of the Australian Antarctic explorer Sir Douglas Mawson. Mawson was listed on the Register of the National Estate in 2001 and listed on the Commonwealth Heritage List on 22 June 2004, reflecting the post-World War Two revival of Australia's scientific research and territorial interests in Antarctica. Purpose Mawson Station is a base for scientific research programs including an underground cosmic ray detector, various long-term meteorological aeronomy and geomagnetic studies, as well as ongoing cons ...
