Aviator Glacier
Aviator Glacier is a major valley glacier in Antarctica that is over long and wide, descending generally southward from the plateau of Victoria Land along the west side of Mountaineer Range, and entering Lady Newnes Bay between Cape Sibbald and Hayes Head where it forms the Aviator Glacier Tongue. A glacier is a mass of ice with sufficient thickness to flow away from the source area in lobes, tongues or masses. Glaciers are usually found at high latitudes or high elevations. The glacier was photographed from the air by Captain W.M. Hawkes, US Navy, on the historic first flight from New Zealand to McMurdo Sound on December 17, 1955. An attempt to reconnoiter it by helicopter and to land a party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE) on it had to be abandoned when USS ''Glacier'' was damaged in pressure ice in December 1958. It was named by NZGSAE, 1958–59, as a tribute to the hazardous work of pilots and other airmen in Antarctic exploratory and sci ...

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 A meteorite is a solid piece of debris from an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern 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 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 measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where ve ... [...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 hundredth an ...

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 Geolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Ranges Of Victoria Land
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
