John Nunatak
John Nunatak () is an isolated granite nunatak in Antarctica, lying north of the Pirrit Hills. The nunatak was examined by United States Antarctic Research Program geologists Edward Thiel and Campbell Craddock on December 13, 1959, in the course of an airlifted geophysical traverse along the 88th meridian West. It was named by the Advisory Committee on Antarctic Names after steelworker Orlan F. John, U.S. Navy, who lost his life in a construction accident at McMurdo Sound McMurdo Sound is a sound in Antarctica. It is the southernmost navigable body of water in the world, and is about from the South Pole. Captain James Clark Ross discovered the sound in February 1841, and named it after Lt. Archibald McMurdo ..., November 2, 1960. References Nunataks of Ellsworth Land {{EllsworthLand-geo-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Pirrit Hills
Pirrit Hills () is an isolated group of rocky peaks and nunataks about 7 nautical miles (13 km) in extent, lying southward of the Ellsworth Mountains, between the Heritage Range and Nash Hills. The feature was positioned by the U.S. Ellsworth-Byrd Traverse Party in December 1958. It was named by the Advisory Committee on Antarctic Names (US-ACAN) for John Pirrit, a glaciologist with the traverse party who had wintered at Ellsworth Station. Pirrit was scientific leader at Byrd Station in 1959.

United States Antarctic Research Program
The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. scientific research and related logistics in Antarctica as well as aboard ships in the Southern Ocean. United States Antarctic Program The United States established the U.S. Antarctic Research Program (USARP) in 1959—the name was later changed to the U.S. Antarctic Program—immediately following the success of the International Geophysical Year (IGY). Today, the National Science Foundation (NSF) has a Presidential Mandate to manage the United States Antarctic Program, through which it operates three year-round research stations and two research vessels, coordinates all U.S. science on the southernmost continent, and works with other federal agencies, the U.S. military, an ...

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 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.

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] |

McMurdo Sound
McMurdo Sound is a sound in Antarctica. It is the southernmost navigable body of water in the world, and is about from the South Pole. Captain James Clark Ross discovered the sound in February 1841, and named it after Lt. Archibald McMurdo of HMS ''Terror''. The sound today serves as a resupply route for cargo ships and for airplanes that land on the floating ice airstrips near McMurdo Station. Physical characteristics Wildlife in the sound include killer whales, seals, Adélie penguins, and emperor penguins. Boundary and Extents The sound extends approximately 55 kilometers (34 mi) in length and width, and opens into the larger Ross Sea to the north. To the south, the sound is bounded by the Ross Ice Shelf cavity, to the west lies the Royal Society Range, and to the east is Ross Island. McMurdo Sound is separated from the McMurdo Ice Shelf (itself part of the Ross Ice Shelf) by the Haskell Strait. Winter Quarters Bay lies at the south end of the Sound, and is the s ...
