Moulton Escarpment
The Thiel Mountains () are isolated, mainly snow-capped mountains of the Transantarctic Mountains System, located in the Ellsworth Land region of Antarctica. The mountain range is long, is located roughly between the Horlick Mountains and the Pensacola Mountains, and extends from Moulton Escarpment on the west to Nolan Pillar on the east. Major components include Ford Massif (), Bermel Escarpment and a group of eastern peaks near Nolan Pillar. Discovery and naming The Thiel Mountains were observed and first positioned by the United States Antarctic Research Program (USARP) Horlick Mountains Traverse Party, 1958–59. They were surveyed by the United States Geological Survey (USGS) Thiel Mountains parties of 1960–61 and 1961–62. They were named by Advisory Committee on Antarctic Names (US-ACAN) after Edward C. Thiel, traverse seismologist at Ellsworth Station and the Pensacola Mountains in 1957. In December 1959, he made airlifted geophysical observations along the 88th ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic 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 Climate of Antarctica#Precipitation, 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 temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

Hamilton Cliff
Ford Massif () is a broad, snow-topped massif long and wide, forming the major topographic landmark of the northern Thiel Mountains in Antarctica. The massif rises to , is essentially flat, and terminates in steep rock cliffs in all but the southern side. Discovery and naming The Ford Massif was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for geologist Arthur B. Ford of the United States Geological Survey (USGS). He was co-leader of the 1960–61 USGS Thiel Mountains survey party and leader of the 1961–62 geologic party to these mountains. Ford led geological parties working in the Pensacola Mountains in several austral seasons, 1962–63 to 1978–79. Location The Ford Massif is the northern past of the Thiel Mountains, separated from the Bermel Escarpment by the Counts Icefall. The Moulton Escarpment lies to the west. Gray Spur is in the southeast of the massif, separated by the Aaron Glacier from Janulis Spur to its north. North of Janulis s ...

Nolan Pillar
The Bermel Escarpment is a snow and rock escarpment, long, extending from the base of the Ford Massif to King Peak, in the Thiel Mountains of Antarctica. The escarpment drops from the Antarctic Plateau to the ice surface north of these mountains. Discovery and naming The Bermel Escarpment was named by the United States Advisory Committee on Antarctic Names (US-ACAN) after Peter F. Bermel, a cartographer with the United States Geological Survey (USGS). Bermel was co-leader (with Arthur B. Ford) of the USGS Thiel Mountains party which surveyed the mountains in 1960–61, and also leader of USGS Topo East and Topo West, 1962–63, in which geodetic control was extended from the area of Cape Hallett to the Wilson Hills (Topo West), and from the foot of Beardmore Glacier through the Horlick Mountains (Topo East). Location The Bermel Escarpment extends southeast from the Counts Icefall, which separates it from the Ford Massif to the north. It faces northeast, dropping from the pola ...

International Association Of Antarctica Tour Operators
The International Association of Antarctica Tour Operators (IAATO) was founded in 1991 by seven companies. The primary goal of the association is to "''advocate and promote the practice of safe and environmentally responsible private-sector travel to the Antarctic''". Since the group's inception membership has grown to over 100 members. In addition there are tour groups working outside the association which may not follow its safety and environmental guidelines. The need for an association like the IAATO is that eight countries have made territorial claims in Antarctica Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. .... However, no country recognizes the claim of any other country. In fact, in some cases, countries claim the same piece of the continent. Therefore, it is rarely clear ...

Wilkes Station
Wilkes Station was an Antarctic research station established 29 January 1957 by the United States as one of seven U.S. stations established for the International Geophysical Year (IGY) program in Antarctica. It was taken over by Australia on 7 February 1959. Environmental difficulties at this site lead to it being abandoned in 1969, with the Australians establishing a new base, Casey Station. History Wilkes Station was named after Charles Wilkes, a 19th-century American explorer who discovered the phenomenon of the continental margin, which helped prove that Antarctica was a continent. Wilkes was one of seven bases that the United States built for the IGY, which also included McMurdo, Hallett, Admundsen-Scott (South Pole Station), Ellsworth, Byrd, and Little America. Of these only McMurdo and Admundsen-Scott are still operated by the 21st century. Personnel from the United States Navy constructed the main part of Wilkes in a period of 16 days in January and February 19 ...

P2V Neptune
The Lockheed P-2 Neptune (designated P2V by the United States Navy prior to September 1962) is a Maritime patrol aircraft, maritime patrol and anti-submarine warfare (ASW) aircraft. It was developed for the US Navy by Lockheed Corporation, Lockheed to replace the Lockheed Ventura, Lockheed PV-1 Ventura and PV-2 Harpoon, and was replaced in turn by the Lockheed P-3 Orion. Designed as a land-based aircraft, the Neptune never made a carrier landing, but a small number were converted and deployed as carrier-launched (using JATO assist), stop-gap nuclear bombers that would have to land on shore or ditch. The type was successful in export, and saw service with several armed forces. Design and development Development of a new land-based patrol bomber began early in World War II, with design work starting at Lockheed's Vega Aircraft Corporation, Vega subsidiary as a private venture on 6 December 1941.Scutts ''Air International'' January 1995, pp. 42–43. At first, the new design was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ellsworth Station
Ellsworth Scientific Station (, or simply ''Estación Ellsworth'' or ''Base Ellsworth'') was a permanent, all year-round originally American, then Argentine Antarctic scientific research station named after American polar explorer Lincoln Ellsworth. It was located on Gould Bay, on the Filchner Ice Shelf. It was shut down in 1962 over safety concerns due to it being built on increasingly unstable ice, which produced fast deterioration of its superstructures and endangered both personnel and equipment. History Ellsworth Station was built by United States Navy Seabees under the command of Captain Finn Ronne, with the support of the icebreakers USS ''Staten Island'' and USS ''Wyandot'', captained by Francis Gambacorta. The originally planned site for the station was Cape Adams, but when the terrain proved impractical due to huge ice cliffs, an alternate location on Gould Bay was selected, on the western coast of the Weddell Sea over the Filchner Ice Shelf, and close to the Arg ...

Edward C
Edward is an English male name. It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortunate; prosperous" and '' weard'' "guardian, protector”. History The name Edward was very popular in Anglo-Saxon England, but the rule of the Norman and Plantagenet dynasties had effectively ended its use amongst the upper classes. The popularity of the name was revived when Henry III named his firstborn son, the future Edward I, as part of his efforts to promote a cult around Edward the Confessor, for whom Henry had a deep admiration. Variant forms The name has been adopted in the Iberian peninsula since the 15th century, due to Edward, King of Portugal, whose mother was English. The Spanish/Portuguese forms of the name are Eduardo and Duarte. Other variant forms include French Édouard, Italian Edoardo and Odoardo, German, Dutch, Czech and Romanian Eduard and Scandinavian Edvard. Short forms include Ed, Eddy, Eddie, Ted, Teddy a ...

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] |

Continent
A continent is any of several large geographical regions. Continents are generally identified by convention (norm), convention rather than any strict criteria. A continent could be a single large landmass, a part of a very large landmass, as in the case of Asia or Europe within Eurasia, or a landmass and nearby islands within its continental shelf. Due to these varying definitions, the number of continents varies; up to seven or as few as four geographical regions are commonly regarded as continents. Most English-speaking world, English-speaking countries recognize seven regions as continents. In order from largest to smallest in area, these seven regions are Asia, Africa, North America, South America, Antarctica, Europe, and Australia (continent), Australia (sometimes called Oceania or Australasia). Different variations with fewer continents merge some of these regions; examples of this are merging Asia and Europe into Eurasia, "Most people recognize seven continents—Asia, ...
