Nash Ridge
Nash Ridge () is a high, massive ridge of eastern Eisenhower Range, about long and wide, projecting between the flow of the O'Kane Glacier and Priestley Glacier, in Victoria Land, Antarctica. Exploration and naming Nash Ridge was mapped by United States Geological Survey (USGS) from surveys and United States Navy air photos, 1955–63. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Harold A. Nash, biologist at McMurdo Station in the 1965-66 and 1966–67 seasons. Location Nash Ridge trends in a northwest-southeast direction. The Priestly Glacier flows past the northeast side of the ridge, and the O'Kane Glacier flows down the southwest side. They join at the southern tip of the ridge. Features of the ridge, from north to south, include Mount Meister, Mount Borgstrom and Lowry Bluff. Nearby features include Eskimo Point, to the west, and Mount New Zealand and Timber Peak to the northwest. Features Features and nearby features include, ...

Eisenhower Range
The Eisenhower Range is a mountain range, about 72 km (45 mi) long and rising to 3,070 m (10,072 ft), which rises between Reeves Névé on the west, Reeves Glacier on the south, and Priestley Glacier on the north and east, in Victoria Land, Antarctica. The range is flat topped and descends gradually to Reeves Névé, but is steep cliffed and marked by sharp spurs along the Priestley Glacier. Mountains of this range include Mount Baxter (2430 m) and Mount Nansen (2740 m). The range was mapped in detail by USGS from surveys and US Navy air photos, 1955–63. Named by US-ACAN for Dwight D. Eisenhower, who was President of the United States in 1954, at the time when the U.S. Navy's Operation Deep Freeze Operation Deep Freeze (OpDFrz or ODF) is codename for a series of United States missions to Antarctica, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on.

O'Kane Glacier
The Priestley Glacier is a major valley glacier, about long, originating at the edge of the Polar Plateau of Victoria Land, Antarctica. The glacier drains southeast between the Deep Freeze and Eisenhower Ranges to enter the northern end of the Nansen Ice Sheet. It was first explored by the Northern Party of the British Antarctic Expedition, 1910–13, and named for Raymond E. Priestley, a geologist with the Northern Party. Priestley Névé () is the névé at the head of Priestley Glacier in Victoria Land. It was named by the New Zealand Antarctic Place-Names Committee in about 1966 in association with Priestley Glacier.

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

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 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. It is operated by the United States through the United States Antarctic Program (USAP), a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,258 residents, and serves as one of three year-round United States Antarctic science facilities. All personnel and cargo going to or coming from Amundsen–Scott South Pole Station first pass through McMurdo. By road, McMurdo is 3 kilometres (1.9 mi) from New Zealand's smaller Scott Base. History The station takes its name from its geographic location on McMurdo Sound, named after Lieutenant Archibald McMurdo of . The ''Terror'', commanded by Irish explorer Francis Crozier, along with expedition flagship ''Erebus'' under command of James Clark Ross, first charted the area ...

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 snow-free Antarctic valleys, which contains the longest river of Antarctica. Further ach ...

Operation Deep Freeze
Operation Deep Freeze (OpDFrz or ODF) is codename for a series of United States missions to Antarctica, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on. (There was an initial operation before Admiral Richard Byrd proposed 'Deep Freeze'). Given the continuing and constant US presence in Antarctica since that date, "Operation Deep Freeze" has come to be used as a general term for US operations in that continent, and in particular for the regular missions to resupply US Antarctic bases, coordinated by the United States military. Task Force 199 was involved. Prior to International Geophysical Year The U.S. Navy already had a record of earlier exploration in Antarctica. As early as 1839, Captain Charles Wilkes led the first U.S. Naval expedition into Antarctic waters. In 1929, Admiral Richard E. Byrd established a naval base at Little America I, led an expedition to explore further inland, and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
