Saturn Glacier
Saturn Glacier () is a glacier lying in southeast Alexander Island, Antarctica. The glacier is 15 nautical miles (28 km) long and 6 nautical miles (11 km) wide, flowing southeast into the George VI Ice Shelf of George VI Sound north of Corner Cliffs. Although the glacier is not situated within Planet Heights, its name derives from the nearby mountain range (Planet Heights) along with many other glaciers named after planets of the Solar System. The nunataks at the head of the glacier are also named after solar system features, for example the Enceladus Nunataks named for a moon of Saturn. The coast in this vicinity was first seen from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. The glacier was surveyed in 1949 by the Falkland Islands Dependencies Survey (FIDS) and named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for the planet Saturn, the sixth planet of the Solar Syste ...

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.

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office. At the end of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USGS
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia.

Uranus Glacier
Uranus Glacier () is a glacier on the east coast of Alexander Island, Antarctica, long and wide at its mouth, flowing east into George VI Sound immediately south of Fossil Bluff. Along the south face of the glacier is an east–west escarpment called Kuiper Scarp. The glacier was probably first seen by Lincoln Ellsworth, who flew directly over it and photographed segments of this coast on November 23, 1935. The portion near the mouth of the glacier was first roughly surveyed in 1936 by the British Graham Land Expedition. It was named by the United Kingdom Antarctic Place-Names Committee for the planet Uranus following the resurvey of its lower portions by the Falkland Islands Dependencies Survey in 1948 and 1949. Although the glacier is named for a planet of the Solar System The Solar System Capitalization of the name varies. The International Astronomical Union, the authoritative body regarding astronomical nomenclature, specifies capitalizing the names of all individu ...

Jupiter Glacier
Jupiter Glacier () is a glacier on the east coast of Alexander Island, Antarctica, long and wide at its mouth, which flows east into George VI Sound to the south of Ablation Valley. It was first photographed from the air on November 23, 1935, by Lincoln Ellsworth and mapped from these photos by W.L.G. Joerg. It was roughly surveyed in 1936 by the British Graham Land Expedition, and was named for the planet Jupiter by the Falkland Islands Dependencies Survey following their surveys in 1948 and 1949. The glacier lies north of Planet Heights, although Jupiter Glacier is not situated within the mountain range, the glacier (along with many other nearby glaciers named after planets of the Solar System) is so named under the association of Planet Heights even though it is not directly a glacier located within this mountainous range.

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).

Saturn
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. It has only one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive. Saturn's interior is most likely composed of a core of iron–nickel and rock (silicon and oxygen compounds). Its core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally, a gaseous outer layer. Saturn has a pale yellow hue due to ammonia crystals in its upper atmosphere. An electrical current within the metallic hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is weaker than Earth's, but which has a magnetic moment 580 times that of Earth due to Saturn's larger size. Saturn's magnetic field strength is around one-twentieth of Jupiter's. The outer atmosphere is g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive features * Anckorn Nunataks, named after J. F. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lincoln Ellsworth
Lincoln Ellsworth (May 12, 1880 – May 26, 1951) was a polar explorer from the United States and a major benefactor of the American Museum of Natural History. Biography Lincoln Ellsworth was born on May 12, 1880, to James Ellsworth and Eva Frances Butler in Chicago, Illinois. He also lived in Hudson, Ohio, as a child. He attended The Hill School and took two years longer than usual to graduate, before entering the Sheffield Scientific School at Yale University. His academic performance was poor, and he subsequently enrolled at Columbia University and McGill before ending his academic career. Lincoln Ellsworth's father, James, a wealthy coal man from the United States, spent US$100,000 to fund Roald Amundsen's 1925 attempt to fly from Svalbard to the North Pole. Amundsen, accompanied by Lincoln Ellsworth, pilot Hjalmar Riiser-Larsen, flight mechanic Karl Feucht and two other team members, set out in two Dornier Wal flying boats, the N24 and N25, in an attempted to reach the ...

Alexander Island
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . Alexander Island is about long in a north–south direction, wide in the north, and wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island. History Alexander Island was discovered on January 28, 1821, by a Russian expedition under Fabian Gottlieb von Bellingshausen, who named it Alexander I Land for the reigning Tsar Alexander I of Russia.

Enceladus Nunataks
The Enceladus Nunataks () are a group of about eight nunataks scattered over a wide area at the head of the drainage basin of Saturn Glacier, in southern Alexander Island, Antarctica. They were mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, 1947–48, and from survey by the Falkland Islands Dependencies Survey, 1948–50. The group was named by the UK Antarctic Place-Names Committee from association with Saturn Glacier, Enceladus Enceladus is the sixth-largest moon of Saturn (19th largest in the Solar System). It is about in diameter, about a tenth of that of Saturn's largest moon, Titan. Enceladus is mostly covered by fresh, clean ice, making it one of the most refle ... being one of the moons of the planet Saturn.
