Beacon Heights
The Quartermain Mountains ( ) are a group of exposed mountains in Antarctica, about long, typical of ice-free features of the McMurdo Dry Valleys, Victoria Land. They are east of the Lashly Mountains, south of the Asgard Range, west of the Kukri Hills and Royal Society Range, and some distance north of the Worcester Range. Exploration The Quartermain Mountains were visited by British expeditions led by Robert Falcon Scott (1901–04 and 1910–13) and Ernest Shackleton (1907–09), who applied several names. Names were added in the years subsequent to the International Geophysical Year, 1957–58, concurrent with research carried out by New Zealand Antarctic Research Programme (NZARP) and United States Antarctic Research Program (USARP) field parties, and to fulfill the requirement for maps compiled from United States Navy aerial photographs, 1947–83. In 1977, the New Zealand Antarctic Place-Names Committee named the mountains after New Zealanders, New Zealand Antarctic histo ...

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 ...

Lashly Glacier
The Lashly Mountains () are a small group of mountains, the most prominent at being Mount Crean, standing south of the head of Taylor Glacier and west of Lashly Glacier, in Victoria Land, Antarctica. Exploration and naming The Lashly Mountains were discovered by the British National Antarctic Expedition (1901–04) and named for William Lashly, a member of the party which explored this area. Location The Lashley Mountains are on the edge of the East Antarctic Ice Sheet. They are west of the Quartermain Mountains and Mount Feather, from which they are separated by the Lashly Glacier, which flows south into The Portal. Mount Crean is the highest peak of the range. Portal Mountain lies to the south of the range, above the Skelton Névé. Geology The Lashly Mountains lie between the intrusive rocks of the McMurdo Dry Valleys and the extrusive rocks of the Transantarctic Mountains. Samples from an unnamed nunatak north of Mount Crean indicated an extrusive origin. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Imre Friedmann
E. Imre Friedmann (1921 – June 11, 2007) was a biologist, Robert O. Lawton Distinguished Professor of Biology at Florida State University and the NASA Ames Research Center, and Director, Polar Desert Research Center. He studied endolithic microbial communities and astrobiology. After escaping the Holocaust, Friedmann received his Ph.D. in botany from the University of Vienna, Austria in 1951, and he died on June 11, 2007. Friedmann made important discoveries of life in extreme environments, particularly cryptoendolithic microbial communities that grow within rocks in deserts, including those of Antarctica and the Negev Desert in Israel. He was also interested in terraforming and wrote several articles about the possibility of terraforming Mars using microbes. In later years he was involved with investigations of martian meteorite ALH84001, which was claimed to contain evidence for early microbial life on Mars. He was a Foreign Member of the Hungarian Academy of ... [...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] |

British National Antarctic Expedition
The ''Discovery'' Expedition of 1901–1904, known officially as the British National Antarctic Expedition, was the first official British exploration of the Antarctic regions since the voyage of James Clark Ross sixty years earlier (1839–1843). Organized on a large scale under a joint committee of the Royal Society and the Royal Geographical Society (RGS), the new expedition carried out scientific research and geographical exploration in what was then largely an untouched continent. It launched the Antarctic careers of many who would become leading figures in the Heroic Age of Antarctic Exploration, including Robert Falcon Scott who led the expedition, Ernest Shackleton, Edward Wilson, Frank Wild, Tom Crean and William Lashly. Its scientific results covered extensive ground in biology, zoology, geology, meteorology and magnetism. The expedition discovered the existence of the only McMurdo Dry Valleys, snow-free Antarctic valleys, which contains the longest river of ...

Taylor Glacier
The Taylor Glacier () is a glacier in Antarctica about long, flowing from the plateau of Victoria Land into the western end of Taylor Valley, north of the Kukri Hills. It flows to the south of the Asgard Range. The middle part of the glacier is bounded on the north by the Inland Forts and on the south by Beacon Valley. History The Taylor Glacier was discovered by the British National Antarctic Expedition (BrNAE, 1901–1904) and at that time thought to be a part of Ferrar Glacier. The Western Journey Party of the Terra Nova Expedition, British Antarctic Expedition of 1910 determined that the upper and lower portions of what was then known as Ferrar Glacier are apposed, i.e., joined in Siamese-twin fashion north of Knobhead. With this discovery Robert F. Scott, Robert Falcon Scott named the upper portion for Thomas Griffith Taylor, geologist and leader of the Western Journey Party.
