Hemmen Ice Rise
Hemmen Ice Rise () is an ice rise long and wide, with an estimated area of , located off the northwest corner of Berkner Island in the Ronne Ice Shelf, Antarctica. The feature appears for the first time on a chart prepared at Ellsworth Station in 1957 by Captain Finn Ronne, U.S. Navy Reserve. The ice rise was subsequently noted in U.S. Earth Resources Technology Satellite imagery. It was named by the UK Antarctic Place-Names Committee for George E. Hemmen, Executive Secretary of the Scientific Committee on Antarctic Research in 1972; he served with the Falkland Islands Dependencies Survey as a meteorological observer at Admiralty Bay, 1952–53, and as Base Leader at Deception Island, 1953–54, and with the Royal Society Antarctic Expedition Royal may refer to: People * Royal (name), a list of people with either the surname or given name * A member of a royal family Places United States * Royal, Arkansas, an unincorporated community * Royal, Illinois, a village * Royal, ...

Ice Rise
An ice rise is a clearly defined elevation of the otherwise very much flatter ice shelf, typically dome-shaped and rising several hundreds of metres above the surrounding ice shelf . An ice rise forms where the ice shelf touches the seabed due to a locally increased elevation of the seabed, which however remains below sea level. (In contrast, an elevation in the seabed that extends above sea level is defined as an island). The ice shelf flows over the seabed elevation, completely covering it with ice, thereby forming an ice rise. The resulting stress increases cause crevasse formation around the ice rise. An island within and totally covered by the ice shelf may appear the same as an ice rise. Elaborate measurements may be required to distinguish between these two geographic features. Although ice rises are typically located within the ice shelf area, they can partially face the open sea. At present, ice rises are found only within the ice shelves of Antarctica. The largest ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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] |
UK 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 Scientific Committee on Antarctic Research, 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.

Scientific Committee On Antarctic Research
The Scientific Committee on Antarctic Research (SCAR) is an interdisciplinary body of the International Science Council (ISC). SCAR coordinates international scientific research efforts in Antarctica, including the Southern Ocean. SCAR's scientific work is administered through several discipline-themed ''science groups''. The organisation has observer status at, and provides independent advice to Antarctic Treaty Consultative Meetings, and also provides information to other international bodies such as the Intergovernmental Panel on Climate Change (IPCC) and the United Nations Framework Convention on Climate Change (UNFCCC). History At the International Council of Scientific Unions (ICSU)’s Antarctic meeting held in Stockholm from 9–11 September 1957, it was agreed that a committee should be created to oversee scientific research in Antarctica. At the time there were 12 nations actively conducting Antarctic research and they were each invited to nominate one delegate to ...

Admiralty Bay (South Shetland Islands)
Admiralty Bay is an irregular bay, wide at its entrance between Demay Point and Martins Head, indenting the southern coast of King George Island for , in the South Shetland Islands of Antarctica. The name appears on a map of 1822 by Captain George Powell, a British sailor, and is now established in international usage. The Henryk Arctowski Polish Antarctic Station is situated on the bay, as is the Comandante Ferraz Brazilian Antarctic Base. It has been designated an Antarctic Specially Managed Area (ASMA 1). Description The bay has three fjords: Martel, Mackellar, and Ezcurra. A mariner's guide to the region pronounced the bay to have the best anchorage of any in the South Shetlands, "being well-sheltered all around and having moderate depths over a bottom of good, stiff clay. Ice from the glaciers is frequently troublesome." Chilean scientists have claimed that Amerinds visited the area, due to stone artifacts recovered from bottom-sampling operations in the bay. how ...

Deception Island
Deception Island is an island in the South Shetland Islands close to the Antarctic Peninsula with a large and usually "safe" natural harbor, which is occasionally troubled by the underlying active volcano. This island is the caldera of an active volcano, which seriously damaged local scientific stations in 1967 and 1969. The island previously held a whaling station. It is now a tourist destination with over 15,000 visitors per year. Two research stations are operated by Argentina and Spain during the summer season. While various countries have asserted sovereignty, it is still administered under the Antarctic Treaty System. Geography Located within the Bransfield Strait, the island is roughly circular and horseshoe-shaped, with a maximum diameter around . The highest peak, Mont Pond on the east side of the island, has an elevation of , while Mount Kirkwood on the west has an elevation of . Over half (57%) of the island is covered by glaciers up to 10 m thick, ice-cor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
