Strahan Glacier
Strahan Glacier () is a glacier flowing north into the sea 1.5 nautical miles (2.8 km) west of Stevens Rock, midway between Cape Daly and Cape Fletcher, Antarctica. It was discovered in February 1931 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Douglas Mawson. Mawson named it for Frank Strahan, Assistant Secretary, Prime Minister's Department (Australia), 1921–35. See also * List of glaciers in the Antarctic * Glaciology References * Glaciers of Mac.

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] |
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.

British Australian New Zealand Antarctic Research Expedition
The British Australian (and) New Zealand Antarctic Research Expedition (BANZARE) was a research expedition into Antarctica between 1929 and 1931, involving two voyages over consecutive Austral summers. It was a British Commonwealth initiative, driven more by geopolitics than science, and funded by the United Kingdom, Australia and New Zealand. The leader of the BANZARE was Sir Douglas Mawson and there were several subcommanders (Captain K.N. MacKenzie, who replaced Captain John King Davis for the second summer) on board the RRS Discovery, the ship previously used by Robert Falcon Scott. The BANZARE, which also made several short flights in a small plane, mapped the coastline of Antarctica and discovered Mac. Robertson Land and Princess Elizabeth Land (which later was claimed as part of the Australian Antarctic Territory). The voyages primarily comprised an "acquisitive exploratory expedition", with Mawson making proclamations of British sovereignty over Antarctic lands at each o ...

Douglas Mawson
Sir Douglas Mawson OBE FRS FAA (5 May 1882 – 14 October 1958) was an Australian geologist, Antarctic explorer, and academic. Along with Roald Amundsen, Robert Falcon Scott, and Sir Ernest Shackleton, he was a key expedition leader during the Heroic Age of Antarctic Exploration. Mawson was born in England and came to Australia as an infant. He completed degrees in mining engineering and geology at the University of Sydney. In 1905 he was made a lecturer in petrology and mineralogy at the University of Adelaide. Mawson's first experience in the Antarctic came as a member of Shackleton's ''Nimrod'' Expedition (1907–1909), alongside his mentor Edgeworth David. They were part of the expedition's northern party, which became the first to attain the South Magnetic Pole and to climb Mount Erebus. After his participation in Shackleton's expedition, Mawson became the principal instigator of the Australasian Antarctic Expedition (1911–1914). The expedition explored thousand ...

Frank Strahan
Frank Strahan (2 July 18864 May 1976) was a senior Australian public servant. Between 1935 and 1949, he was Secretary of the Prime Minister's Department. Life and career Strahan was born in Fryerstown, Victoria on 2 July 1886. In November 1935, Strahan was appointed Secretary of the Prime Minister's Department. In the role, he became the first member of the Commonwealth Public Service to attend Cabinet when he attended a meeting of the Third Menzies Ministry in July 1941. In 1941 when the Department of External Territories was established (it was previously an office in the Prime Minister's Department), Strahan was named its Secretary. Strahan served in dual roles at the head of the Territories Department and the Prime Minister's Department until 1944, when J.R. Halligan was appointed to head the Department of External Territories. Strahan retired in August 1949. He died on 4 May 1976 in Camberwell, and his body was cremated. Awards Whilst an Assistant Secretary at the P ...

Prime Minister
A prime minister, premier or chief of cabinet is the head of the cabinet and the leader of the ministers in the executive branch of government, often in a parliamentary or semi-presidential system. Under those systems, a prime minister is not the head of state, but rather the head of government, serving under either a monarch in a democratic constitutional monarchy or under a president in a republican form of government. In parliamentary systems fashioned after the Westminster system, the prime minister is the presiding and actual head of government and head/owner of the executive power. In such systems, the head of state or their official representative (e.g., monarch, president, governor-general) usually holds a largely ceremonial position, although often with reserve powers. Under some presidential systems, such as South Korea and Peru, the prime minister is the leader or most senior member of the cabinet, not the head of government. In many systems, the prime minister ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Glaciers In The Antarctic
There are many glaciers in the Antarctic. This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice. The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. Ice streams are a type of glacier and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System).

Glaciology
Glaciology (; ) is the scientific study of glaciers, or more generally ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology. The impact of glaciers on people includes the fields of human geography and anthropology. The discoveries of water ice on the Moon, Mars, Europa and Pluto add an extraterrestrial component to the field, which is referred to as "astroglaciology". Overview A glacier is an extended mass of ice formed from snow falling and accumulating over a long period of time; glaciers move very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers. Areas of study within glaciology include glacial history and the reconstruction of past glaciation. A glaciologist is a person who studies glaciers. A glacial geologist ...
