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] |

Walton Mountains
Walton Mountains is an isolated chain of three predominantly snow-covered mountain masses, rising to about 1,450 m at Mount McArthur, extending south from Schubert Inlet for 25 miles (40 km) in central Alexander Island, Antarctica. The mountains were first sighted from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. Resighted from the air by the United States Antarctic Service in 1940, and in 1947 by the Ronne Antarctic Research Expedition under Ronne. Ronne named the mountains after Lieutenant Colonel R.C. Walton, United States Marine Corps, of the Office of Naval Research, who was instrumental in obtaining the loan of a ship from the Navy and in securing Navy assistance for the Ronne expedition.

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.

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] |
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] |
Moses T
Moses hbo, מֹשֶׁה, Mōše; also known as Moshe or Moshe Rabbeinu (Mishnaic Hebrew: מֹשֶׁה רַבֵּינוּ, ); syr, ܡܘܫܐ, Mūše; ar, موسى, Mūsā; grc, Mωϋσῆς, Mōÿsēs () is considered the most important prophet in Judaism and one of the most important prophets in Christianity, Islam, the Druze faith, the Baháʼí Faith and other Abrahamic religions. According to both the Bible and the Quran, Moses was the leader of the Israelites and lawgiver to whom the authorship, or "acquisition from heaven", of the Torah (the first five books of the Bible) is attributed. According to the Book of Exodus, Moses was born in a time when his people, the Israelites, an enslaved minority, were increasing in population and, as a result, the Egyptian Pharaoh worried that they might ally themselves with Egypt's enemies. Moses' Hebrew mother, Jochebed, secretly hid him when Pharaoh ordered all newborn Hebrew boys to be killed in order to reduce the population ...

VX-6
Air Development Squadron Six (VX-6 or AIRDEVRON SIX, commonly referred to by its nickname, "puckered penguins") was a United States Navy Air Development Squadron based at McMurdo Station, Antarctica. Established at Naval Air Station Patuxent River, Maryland on 17 January 1955, the squadron's mission was to conduct operations in support of Operation Deep Freeze, the operational component of the United States Antarctic Program. Using the tail code ''XD'', the squadron flew numerous fixed-wing aircraft and helicopters over the course of its existence—many of which were pioneering endeavors. For example, the first air link between Antarctica and New Zealand was established by men and aircraft of VX-6 in 1955. The following year, a ski-equipped R4D Dakota of VX-6 became the first aircraft to land at the South Pole. In 1961, the first emergency midwinter medical evacuation flight was conducted from Byrd Station to Christchurch. In 1963, an LC-130F Hercules of VX-6 made the longest ...

Coal Nunatak
Coal Nunatak () is a flat-topped rock mass with steep cliffs facing south, standing southwest of Corner Cliffs on the southeast corner of Alexander Island, Antarctica. Lincoln Ellsworth first noted it from the air on November 23, 1935, and mapped it from photos obtained on that flight by W.L.G. Joerg. Observed from the northwest (the direction from which Ellsworth photographed this nunatak), only the summit protrudes above the coastal ice, and it was uncertain whether this was a peak on Alexander Island or an island in George VI Sound. Its true nature was determined by the Falkland Islands Dependencies Survey (FIDS) who visited and surveyed this nunatak in 1949. So named by FIDS for exposures of thin lenses of coal occur there.Stewart, J., 2011. ''Antarctica: An Encyclopedia,'' 2nd ed.
