Spilhaus Inlet
Spilhaus Inlet () is an ice-filled inlet which is the southernmost of the three inlets indenting the east side of Berkner Island, Filchner Ice Shelf.

Berkner Island
Berkner Island (also known as the Berkner Ice Rise or as Hubley Island) is an Antarctic ice rise, where bedrock below sea level has caused the surrounding ice sheet to create a dome. If the ice cap were removed, the island would be underwater. Berkner Island is completely ice-covered and is about long and wide, with an area of . It is surrounded by the Filchner-Ronne Ice Shelf. The northernmost point of the Berkner is about from the open sea. It lies in the overlapping portion of the Argentine and the British Antarctic territorial claims. The island rises to ( according to other sources) and separates the Ronne Ice Shelf from the Filchner Ice Shelf. It is characterized by two domes, ''Reinwarthhöhe'' in the north (), and ''Thyssenhöhe'' in the south (). It is indented by three bays on the eastern side, which are, from north to south, the McCarthy Inlet, the Roberts Inlet, and the Spilhaus Inlet. The southern tip is named the Mulvaney Promontory. Gould Bay is on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Filchner Ice Shelf
Wilhelm Filchner (13 September 1877 – 7 May 1957) was a German army officer, scientist and explorer. He conducted several surveys and scientific investigations in China, Tibet and surrounding regions, and led the Second German Antarctic Expedition, 1911–13. As a young military officer, Filchner gained an early reputation for dash and daring, following his travel exploits in Russia and the Pamir Mountains range. After further technical studies, he developed expertise in geography and geophysics, before leading a major scientific survey in Tibet and western China in 1903–05. In 1909 he was appointed to organise and lead the forthcoming German expedition to the Antarctic, with both scientific and geographical objectives involving extensive exploration of the continent's interior. During the expedition his ship became trapped in the Weddell Sea ice, drifting for eight months and preventing Filchner from establishing a land base, thus failing in its main objective.

Ellsworth Station
Ellsworth Scientific Station ( es, Estación Científica Ellsworth, 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 ...

Finn Ronne
Finn Ronne (December 20, 1899 – January 12, 1980) was a Norwegian-born U.S. citizen and Antarctic explorer. Background Finn Ronne was born in Horten, in Vestfold county, Norway. His father, Martin Rønne (1861–1932), was a polar explorer who served in Roald Amundsen's successful expedition to the South Pole. Ronne received his education in engineering at Horten Technical College. In 1923 Finn Ronne immigrated to the U.S. and gained citizenship in 1929. After working at Westinghouse Electric Corporation for some years, he took part in two of Richard E. Byrd's expeditions to the South Pole, and in 1939 Ronne served as Byrd's executive officer helping discover one thousand miles of new coastline. After serving several years in the United States Navy, gaining the rank of captain, Ronne returned to Antarctica in the 1940s, with support of the American Geographical Society as the leader of the Ronne Antarctic Research Expedition. From 1946 to 1948 his team mapped and explored t ... [...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] |
Athelstan Spilhaus
Athelstan Frederick Spilhaus (November 25, 1911 – March 30, 1998) was a South African-American geophysicist and oceanographer. Among other accomplishments, Spilhaus is credited with proposing the establishment of Sea Grant Colleges at a meeting of the American Fisheries Society in 1963 as a parallel to the successful land-grant colleges, which he claimed was "one of the best investments this nation ever made. The same kind of imagination and foresight should be applied to the exploration of the sea." Biography Spilhaus was born in 1911 in Cape Town, South Africa, grandson of the mathematician Thomas Muir. In 1936, Spilhaus joined the Woods Hole Oceanographic Institution in Massachusetts, where he developed the bathythermograph, which made the measurement of ocean depths and temperatures from a moving vessel possible, a device which proved indispensable to submarine warfare. This invention established his international reputation. He became a US citizen in 1946. Later, he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Science Board
The National Science Board (NSB) of the United States establishes the policies of the National Science Foundation (NSF) within the framework of applicable national policies set forth by the President and the Congress. The NSB also serves as an independent policy advisory body to the President and Congress on science and engineering research and education issues. The Board has a statutory obligation to "...render to the President and to the Congress reports on specific, individual policy matters related to science and engineering and education in science engineering, as Congress or the President determines the need for such reports," (e.g. Science and Engineering Indicators; Report to Congress on Mid-scale Instrumentation at the National Science Foundation). All Board members are presidential appointees. NSF's director serves as an ex officio 25th member and is appointed by the President and confirmed by the US Senate. Mission statement The Board's mission statement states: "Suppor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inlets Of Antarctica
An inlet is a (usually long and narrow) indentation of a shoreline, such as a small arm, bay, sound, fjord, lagoon or marsh, that leads to an enclosed larger body of water such as a lake, estuary, gulf or marginal sea. Overview In marine geography, the term "inlet" usually refers to either the actual channel between an enclosed bay and the open ocean and is often called an "entrance", or a significant recession in the shore of a sea, lake or large river. A certain kind of inlet created by past glaciation is a fjord, typically but not always in mountainous coastlines and also in montane lakes. Multi-arm complexes of large inlets or fjords may be called sounds, e.g., Puget Sound, Howe Sound, Karmsund (''sund'' is Scandinavian for "sound"). Some fjord-type inlets are called canals, e.g., Portland Canal, Lynn Canal, Hood Canal, and some are channels, e.g., Dean Channel and Douglas Channel. Tidal amplitude, wave intensity, and wave direction are all factors that influ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
