Bender Mountains
The Bender Mountains () are a small group of mountains southwest of the Berry Peaks, between the southeast edge of the Ross Ice Shelf and the Watson Escarpment. Exploration and naming The Bender Mountains were mapped by the United States Geological Survey (USGS) from ground surveys and from United States Navy air photos, 1960–63. They were named by the Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant Commander Leslie C. Bender, U.S. Navy, an aircraft commander at McMurdo Station, 1962–63 and 1963–64.} Location The Bender Mountains are in a generally flat area south of the Ross Ice Shelf and west of the Reedy Glacier, which enters the ice shelf to the north of the mountains. They are south of the Watson Escarpment and east of the Harold Byrd Mountains, which in turn are east of the Leverett Glacier. Features of the mountains include Mount Fiedler and Mount Mahan. To the northeast are the Berry Peaks including Scallop Ridge and Gallaher Peak. McCaslin Nuna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marie Byrd Land
Marie Byrd Land (MBL) is an unclaimed region of Antarctica. With an area of , it is the largest unclaimed territory on Earth. It was named after the wife of American naval officer Richard E. Byrd, who explored the region in the early 20th century. The territory lies in West Antarctica, east of the Ross Ice Shelf and the Ross Sea and south of the Pacific Ocean portion of the Antarctic or Southern Ocean, extending eastward approximately to a line between the head of the Ross Ice Shelf and Eights Coast. It stretches between 158°W and 103°24'W. The inclusion of the area between the Rockefeller Plateau and Eights Coast is based upon Byrd's exploration. Overview Because of its remoteness, even by Antarctic standards, most of Marie Byrd Land (the portion east of 150°W) has not been claimed by any sovereign state. It is by far the largest single unclaimed territory on Earth, with an area of , including Eights Coast, immediately east of Marie Byrd Land. In 1939, United States ...

Ross Ice Shelf
The Ross Ice Shelf is the largest ice shelf of Antarctica (, an area of roughly and about across: about the size of France). It is several hundred metres thick. The nearly vertical ice front to the open sea is more than long, and between high above the water surface. Ninety percent of the floating ice, however, is below the water surface. Most of the Ross Ice Shelf is in the Ross Dependency claimed by New Zealand. It floats in, and covers, a large southern portion of the Ross Sea and the entire Roosevelt Island, Antarctica, Roosevelt Island located in the east of the Ross Sea. The ice shelf is named after James Clark Ross, Sir James Clark Ross, who discovered it on 28 January 1841. It was originally called "The Barrier", with various adjectives including "Great Ice Barrier", as it prevented sailing further south. Ross mapped the ice front eastward to 160° W. In 1947, the U.S. Board on Geographic Names applied the name "Ross Shelf Ice" to this feature and published it in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watson Escarpment
Watson Escarpment () is a major escarpment in the Queen Maud Mountains, trending northward along the east margin of Scott Glacier (Transantarctic Mountains), Scott Glacier, then eastward to Reedy Glacier where it turns southward along the glacier's west side. Somewhat arcuate, the escarpment is nearly long, rises above sea level, and above the adjacent terrain. Discovery and naming The north-central part of the escarpment was observed from a vantage point on Supporting Party Mountain and was partially mapped in December 1929 by the Byrd Antarctic Expedition geological party under Laurence Gould. The escarpment was more closely observed in December 1934 by the Byrd Antarctic Expedition geological party under Quin Blackburn, and was named by Byrd for Thomas J. Watson, American business executive, a patron of this expedition. The escarpment and its related features was mapped in detail by United States Geological Survey (USGS) from surveys and United States Navy air photos, 1960â ...

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

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 an American Antarctic research station on the southern tip of Ross Island. 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 1,500 residents, though the population fluctuates seasonally; during the antarctic night, there are fewer than two hundred people. It serves as one of three year-round United States Antarctic science facilities. Personnel and cargo going to or coming from Amundsen–Scott South Pole Station usually first pass through McMurdo, either by flight or by the McMurdo to South Pole Traverse; it is a hub for activities and science projects in Antarctica. McMurdo, Amundsen-Scott, and Palmer are the three non-seasonal United States stations on the continent, though by the Antarctic Treaty System the bases are not a legal claim (though the right is not forfeited); they are dedicated to ...

Leverett Glacier
The Leverett Glacier () is about long and wide, flowing from the Antarctic Plateau to the south end of the Ross Ice Shelf through the Queen Maud Mountains. It is an important part of the South Pole Traverse from McMurdo Station to the Admundson–Scott South Pole Station, providing a route for tractors to climb from the ice shelf through the Transantarctic Mountains to the polar plateau. Discovery and naming The Leverett Glacier was discovered in December 1929 by the Byrd Antarctic Expedition geological party under Laurence Gould, and named by him for Frank Leverett, an eminent geologist at the University of Michigan and an authority on the glacial geology of the central United States. Course The Leverett Glacier forms on the polar plateau to the west of the California Plateau. The Stanford Plateau is to the east. It flows north through the Watson Escarpment between Mount Beazley to the west and McLean Peak to the east, then turns to flow in a north-north-west directi ...
