Ramseier Glacier
Ramseier Glacier () is a steep cirque-type glacier, 5 nautical miles (9 km) long, flowing southwest to enter Byrd Glacier immediately east of Mount Rummage. Named by the Advisory Committee on Antarctic Names (US-ACAN) for Rene O. Ramseier, glaciologist at McMurdo and South Pole Stations, 1960–61 and 1961-62 seasons.

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 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 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. Between latitudes 35°N and 35°S, glaciers occur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Byrd Glacier
The Byrd Glacier is a major glacier in Antarctica, about long and wide, draining an extensive area of the polar plateau and flowing eastward between the Britannia Range and Churchill Mountains to discharge into the Ross Ice Shelf at Barne Inlet. Its valley below the glacier used to be recognised as one of the lowest points not to be covered by water on Earth (assuming ice doesn't count as water), reaching below sea level. It was named by the NZ-APC after Rear Admiral Byrd, US Navy Antarctic explorer. On the south side of Byrd Glacier is Blake Massif.

Mount Rummage
Hughes Basin () is a large basinlike névé in the Britannia Range of Antarctica which is bounded except to the south by the Ravens Mountains, Mount Henderson, Mount Olympus and Mount Quackenbush. The feature is long and the ice surface descends north–south from near Mount Olympus to near Darnell Nunatak, where there is discharge to Byrd Glacier. It was named after Terence J. Hughes of the Department of Geological Sciences and the Institute of Quaternary Studies at the University of Maine, Orono, who made an intensive study of the Byrd Glacier in 1978–79, entailing photogrammetric determination of the elevation of the ice surface and its velocity, radio-echo sounding from 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.

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 Geolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McMurdo
Vice-Admiral Archibald McMurdo (24 September 1812 – 11 December 1875) was a Scottish naval officer and polar explorer after whom Antarctica's McMurdo Sound, McMurdo Station, McMurdo Ice Shelf, McMurdo Dry Valleys and McMurdo–South Pole Highway are named. Early life Archibald William McMurdo was born on September 24, 1812 in Scotland. He was the son of Lieutenant Colonel Archibald McMurdo and grandson of John McMurdo, a chamberlain at Drumlanrig Castle. Career McMurdo joined the Royal Navy on 6 October 1824, at the age of 12. He was promoted to Lieutenant in 1836 for his skill and courage in saving the crew of a shipwrecked whaler from hostile New Zealand natives. He achieved the rank of Commander in 1843 and Captain in 1851. His career included two discovery expeditions aboard HMS ''Terror'', the first to Hudson Bay (1836-1837), the second to Antarctica (1839-1842). In 1836 he served on HMS Volage during its voyage to East India. During the Antarctica voyage, McMur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Pole Stations
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. 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', cf English meridional), 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). Navigation By convention, the ''bottom or down-facing side'' of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
