Koski Glacier
Mill Glacier () is a tributary glacier, wide, flowing northwest between the Dominion Range and the Supporters Range into Beardmore Glacier, Antarctica. It was discovered by the British Antarctic Expedition, 1907–09, and named for Hugh Robert Mill, a British geographer and Antarctic historian. Course The Grosvenor Mountains, a group of widely scattered mountains and nunataks, rises above the polar plateau east of the head of Mill Glacier. The Mill Glacier is a valley glacier that flows down from the Grosvenor Mountains past Otway Massif, then between the Dominion Range and Supporters Range before joining the Beardmore Glacier. The head of the glacier is crossed by the Scott Icefalls. From there it flows northwest between the Dominion Range to the west and the Otway Massif to the east. The Mill Stream Glacier, which is fed from the south by the Burgess Glacier, joins the Mill Glacier from the east to the north of the Otway Massif. The Vandement Glacier and the Koski Glacier ...

Beardmore Glacier
The Beardmore Glacier in Antarctica is one of the largest valley glaciers in the world, being long and having a width of . It descends about from the Antarctic Plateau to the Ross Ice Shelf and is bordered by the Commonwealth Range of the Queen Maud Mountains on the eastern side and the Queen Alexandra Range of the Central Transantarctic Mountains on the western. Its mouth is east of the Lennox-King Glacier. It is northwest of the Ramsey Glacier. Early exploration The glacier is one of the main passages through the Transantarctic Mountains to the great polar plateau beyond, and was one of the early routes to the South Pole despite its steep upward incline. The glacier was discovered and climbed by Ernest Shackleton during his Nimrod Expedition, ''Nimrod'' Expedition of 1908. Although Shackleton turned back at latitude 88° 23' S, just from the South Pole, he established the first proven route towards the pole and, in doing so, became the first person to set foot up ...

Lockheed LC-130
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. Department of Defense in 1962. These four aircraft were bought by the U.S. Navy to support the Navy's Antarctic expedition that was ongoing at the time. The Navy also bought one L ...

South Pole Station
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both west and east. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', ), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant). South is sometimes abbreviated as S. Navigation By convention, the ''bottom or down ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Antarctic Program
The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has a presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. Research stations in Antarctica, scientific research and related Transport in Antarctica, logistics in Antarctica as well as aboard ships in the Southern Ocean. United States Antarctic Program The United States established the U.S. Antarctic Research Program (USARP) in 1959—the name was later changed to the U.S. Antarctic Program—immediately following the success of the International Geophysical Year (IGY). Today, the National Science Foundation (NSF) has a Presidential Mandate to manage the United States Antarctic Program, through which it operates three year-round research stations and two research vessels, coordinates all U.S. science on the southernmost continent, ...

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] |
Robert Falcon Scott
Captain Robert Falcon Scott (6 June 1868 – ) was a British Royal Navy officer and explorer who led two expeditions to the Antarctic regions: the Discovery Expedition, ''Discovery'' expedition of 1901–04 and the Terra Nova Expedition, ''Terra Nova'' expedition of 1910–13. On the first expedition, he set a new southern record by marching to latitude 82°S and discovered the Antarctic Plateau, on which the South Pole is located. On the second venture, Scott led a party of five which reached the South Pole on 17 January 1912, less than five weeks after Amundsen's South Pole expedition. On the return journey from the Pole, a planned meeting with supporting dog teams from the base camp failed, despite Scott's written instructions, and at a distance of from their base camp at Hut Point and approximately from the next depot, Scott and his companions died. When Scott and his party's bodies were discovered, they had in their possession the first Antarctic fossils discovere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glacier
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and 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“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. 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 ever ...

Otway Massif
The Grosvenor Mountains () are a group of widely scattered mountains and nunataks rising above the Antarctic polar plateau east of the head of Mill Glacier, extending from Mount Pratt in the north to the Mount Raymond area in the south, and from Otway Massif in the northwest to Larkman Nunatak in the southeast. Discovery and naming The Grosvenor Mountains were discovered by Rear Admiral Richard E. Byrd on the Byrd Antarctic Expedition flight to the South Pole in November 1929, and named by him for Gilbert Hovey Grosvenor, President of the National Geographic Society, which helped finance the expedition. Several peaks near Mount Raymond were apparently observed by Ernest Shackleton in 1908, although they were then considered to be a continuation of the Dominion Range. Location The Grosvenor Mountains extend south and east from the Otway Massif, which forms the southeast angle of the juncture of the Mill Stream Glacier and the Mill Glacier.

Valley Glacier
Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. Types of glaciers can range from massive ice sheets, such as the Greenland ice sheet, to small cirque glaciers found perched on mountain tops. Glaciers can be grouped into two main categories: * Ice flow is constrained by the underlying bedrock topography * Ice flow is unrestricted by surrounding topography Unconstrained Glaciers Ice sheets and ice caps Ice sheets and ice caps cover the largest areas of land in comparison to other glaciers, and their ice is unconstrained by the underlying topography. They are the largest glacial ice formations and hold the vast majority of the world's fresh water. Ice sheets Ice sheets are the largest form of glacial formation. They are continent-sized ice masses that span areas over . They are dome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
