Doake Ice Rumples
Doake Ice Rumples () is an area of disturbed ice in the Ronne Ice Shelf, extending for about in a northwest–southeast direction between Korff Ice Rise and Henry Ice Rise. It was first visited and mapped in part by the US–International Geophysical Year geophysical traverse party from Ellsworth Station 1957–58, led by Edward Thiel, and was further delineated from U.S. Landsat imagery taken 1974 and from radio echo sounding by the British Antarctic Survey (BAS) in 1981. It was named by the 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 ... after Christopher S.M. Doake, a senior BAS glaciologist from 1973, who has contributed to an understanding of the morphology and dynamics of the Ronne Ice Shelf. References Filchner-Ronne Ice Shelf I ...

Korff Ice Rise
Korff Ice Rise is an ice rise, long and wide, lying east-northeast of Skytrain Ice Rise in the southwestern part of the Ronne Ice Shelf, Antarctica. It was discovered by the US–IGY Ellsworth Traverse Party, 1957–58, and named by the party for Professor Serge A. Korff, vice chairman of the cosmic ray technical panel, U.S. National Committee for the International Geophysical Year, 1957–59. Radar surveying in 2013-2015 by a team from the British Antarctic Survey found the ice to be up to around thick and found evidence that the Raymond Effect was operating beneath the ice divide An ice divide is the boundary on an ice sheet, ice cap or glacier separating opposing flow directions of ice, analogous to a water divide. Ice divides are important for geochronological investigations that use ice cores, since such coring is typi ....

Henry Ice Rise
Henry Ice Rise is a triangular-shaped ice rise about long located between Korff Ice Rise and the southern portion of Berkner Island in the Ronne Ice Shelf, Antarctica. It was first visited by the United States International Geophysical Year geophysical traverse party from Ellsworth Station, 1957–58, and was named by the Advisory Committee on Antarctic Names after Captain Clifford D. Henry of the Military Sealift Command, a veteran American polar sea captain and master of . Henry died aboard his ship, February 16, 1975, while returning from his fourteenth voyage to Antarctica in support of the U.S. Antarctic Research Program.

International Geophysical Year
The International Geophysical Year (IGY; french: Année géophysique internationale) was an international scientific project that lasted from 1 July 1957 to 31 December 1958. It marked the end of a long period during the Cold War when scientific interchange between East and West had been seriously interrupted. Sixty-seven countries participated in IGY projects, although one notable exception was the mainland People's Republic of China, which was protesting against the participation of the Republic of China ( Taiwan). East and West agreed to nominate the Belgian Marcel Nicolet as secretary general of the associated international organization. The IGY encompassed eleven Earth sciences: aurora and airglow, cosmic rays, geomagnetism, gravity, ionospheric physics, longitude and latitude determinations (precision mapping), meteorology, oceanography, seismology, and solar activity. The timing of the IGY was particularly suited for studying some of these phenomena, since it cove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Fil ...

Edward Thiel
Edward C. Thiel (May 4, 1928 – November 9, 1961), was a geologist from the University of Wisconsin and chief seismologist at Ellsworth Station Antarctica, from 1956 to 1958. He was leader of the traverse party that discovered the Thiel Trough submarine valley that was later named in his honor. The Thiel Mountains were also named after him. Thiel was killed on November 9, 1961 while returning from a geomagnetic survey mission to Mirny Station. The P2V-7 (Bu No.140439) Neptune aircraft from US Navy Squadron VX-6 in which he was a passenger crashed at Wilkes Station in Antarctica, where it had refueled overnight, and was en route back to McMurdo Station McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica.

Landsat
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from ; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Antarctic 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 British Admiralty, Admiralty and the Secretary of ... [...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 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. Anc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christopher S
Christopher is the English version of a Europe-wide name derived from the Greek name Χριστόφορος (''Christophoros'' or '' Christoforos''). The constituent parts are Χριστός (''Christós''), " Christ" or " Anointed", and φέρειν (''phérein''), "to bear"; hence the "Christ-bearer". As a given name, 'Christopher' has been in use since the 10th century. In English, Christopher may be abbreviated as " Chris", "Topher", and sometimes "Kit". It was frequently the most popular male first name in the United Kingdom, having been in the top twenty in England and Wales from the 1940s until 1995, although it has since dropped out of the top 100. The name is most common in England and not so common in Wales, Scotland, or Ireland. People with the given name Antiquity and Middle Ages * Saint Christopher (died 251), saint venerated by Catholics and Orthodox Christians * Christopher (Domestic of the Schools) (fl. 870s), Byzantine general * Christopher Lekapenos (d ...
