Mount Canopus
The Nash Range () is a mainly ice-covered coastal range in the Churchill Mountains of Antarctica. Location The Nash Range is 40 nautical miles (70 km) long, bordering the west side of the Ross Ice Shelf between the Dickey and Nimrod Glaciers. The Dickey Glacier flows north into Beaumont Bay to the north of the range. To the south of Bridge Pass, the Algie Glacier flows south along the west edge of the range to enter Nimrod Glacier, which passes round the southern end of the range. The Holyoake Range lies to the southwest of the Nash Range. The Surveyors Range is to the northwest. The range was named by the Ross Sea Committee for Walter Nash who, as Leader of the Opposition and later as Prime Minister of New Zealand, gave strong support to New Zealand participation in the Commonwealth Trans-Antarctic Expedition, 1956–58. Topography The Nash Range is composed of metagreywacke intruded by granite. It trends north-north-west from Cape Wilson in the south to Beaumont Bay ...

Ross Dependency
The Ross Dependency is a region of Antarctica defined by a sector originating at the South Pole, passing along longitudes 160° east to 150° west, and terminating at latitude 60° south. It is claimed by New Zealand, a claim accepted only by the other six countries with territorial claims in Antarctica. Under the 1961 Antarctic Treaty, of which all territorial claimants are signatories, including New Zealand, all claims are held in abeyance. Article IV states: "No acts or activities taking place while the present Treaty is in force shall constitute a basis for asserting, supporting or denying a claim to territorial sovereignty in Antarctica or create any rights of sovereignty in Antarctica". The Dependency takes its name from Sir James Clark Ross, who discovered the Ross Sea, and includes part of Victoria Land, and most of the Ross Ice Shelf. Ross, Balleny, Scott and Roosevelt Islands also form part of the Dependency. History of claim Following his discovery of Victo ...

Cape Hallett
Cape Hallett is a snow-free area (Antarctic oasis) on the northern tip of the Hallett Peninsula on the Ross Sea coast of Victoria Land, East Antarctica. Cape Adare lies to the north. History In 1956, during Operation Deep Freeze II, was damaged by an ice floe at Cape Hallett. Hallett Station The cape was the location of a joint scientific base, Hallett Station, between the United States and New Zealand during the International Geophysical Year of 1957, and was manned permanently until 1964, when there was a major fire. It was then used as a summer only base until 1973. The site is currently being remediated by removing hazardous materials: fuel, and oil stored in several large tanks. This is an ongoing project which will take several years to complete. Antarctic Specially Protected Area An area of 74 ha is protected under the Antarctic Treaty System as Antarctic Specially Protected Area (ASPA) No.106 because it contains habitats with a rich and diverse range of ...

William Henry May
Admiral of the Fleet Sir William Henry May (31 July 1849 – 7 October 1930) was a Royal Navy Officer. As a junior officer he took part an expedition to rescue Commander Albert Markham who had got into difficulty trying to reach the North Pole via Smith Sound, the sea passage between Greenland and Canada's northernmost island, Ellesmere Island. May went on to higher command and served as Third Sea Lord and Controller of the Navy before becoming Commander-in-Chief, Atlantic Fleet. He held the office of Second Sea Lord and Chief of Naval Personnel and in that capacity threatened to resign if the Liberal Government cut the naval estimates any further. Later he became Commander-in-Chief, Home Fleet, in which capacity he encouraged innovative ways of organising his huge fleet including the deployment of cruising formations, the use of fast squadrons and tactical command at squadron level rather than fleet level, and then became Commander-in-Chief, Plymouth. He served in the First ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Laird
Cape Laird () is a rocky cape northwest of Cape May, along the west side of the Ross Ice Shelf, Antarctica. It was named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1960–61) for Malcolm G. Laird, a NZGSAE geologist who took a special interest in the peneplain 390px, Sketch of a hypothetical peneplain formation after an orogeny. In geomorphology and geology, a peneplain is a low-relief plain formed by protracted erosion.

Alligator
An alligator is a large reptile in the Crocodilia order in the genus ''Alligator'' of the family Alligatoridae. The two extant species are the American alligator (''A. mississippiensis'') and the Chinese alligator (''A. sinensis''). Additionally, several extinct species of alligator are known from fossil remains. Alligators first appeared during the Oligocene epoch about 37 million years ago. The name "alligator" is probably an anglicized form of ', the Spanish term for "the lizard", which early Spanish explorers and settlers in Florida called the alligator. Later English spellings of the name included ''allagarta'' and ''alagarto''. Evolution Alligators and caimans split in North America during the early Tertiary or late Cretaceous (about 53 million to about 65 million years ago). The Chinese alligator split from the American alligator about 33 million years ago and probably descended from a lineage that crossed the Bering land bridge during the Neogene. The modern ...

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] |
Cape May
Cape May consists of a peninsula and barrier island system in the U.S. state of New Jersey. It is roughly coterminous with Cape May County, New Jersey, Cape May County and runs southwards from the New Jersey mainland, separating Delaware Bay from the Atlantic Ocean. The southernmost point in New Jersey lies on the cape.

West Antarctica
West Antarctica, or Lesser Antarctica, one of the two major regions of Antarctica, is the part of that continent that lies within the Western Hemisphere, and includes the Antarctic Peninsula. It is separated from East Antarctica by the Transantarctic Mountains and is covered by the West Antarctic Ice Sheet. It lies between the Ross Sea (partly covered by the Ross Ice Shelf), and the Weddell Sea (largely covered by the Filchner-Ronne Ice Shelf). It may be considered a giant peninsula, stretching from the South Pole towards the tip of South America. West Antarctica is largely covered by the Antarctic ice sheet, but there have been signs that climate change is having some effect and that this ice sheet may have started to shrink slightly. Over the past 50 years, the west coast of the Antarctic Peninsula has been - and still is - one of the most rapidly warming parts of the planet, and the coasts of the Peninsula are the only parts of West Antarctica that become (in summer) ice-free ...

Transantarctic Mountains
The Transantarctic Mountains (abbreviated TAM) comprise a mountain range of uplifted (primarily sedimentary rock, sedimentary) rock in Antarctica which extend, with some interruptions, across the continent from Cape Adare in northern Victoria Land to Coats Land. These mountains divide East Antarctica and West Antarctica. They include a number of separately named mountain groups, which are often again subdivided into smaller ranges. The range was first sighted by James Clark Ross in 1841 at what was later named the Ross Ice Shelf in his honour. It was first crossed during the British National Antarctic Expedition of 1901-1904. Geography The mountain range stretches between the Ross Sea and the Weddell Sea, the entire width of Antarctica, hence the name. With a total length of about , the Transantarctic Mountains are one of the longest mountain ranges on Earth. The Antarctandes are even longer, having in common with the Transantarctic Mountains the ranges from Cape Adare to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Pole
The South Pole, also known as the Geographic South Pole, Terrestrial South Pole or 90th Parallel South, is one of the two points where Earth's axis of rotation intersects its surface. It is the southernmost point on Earth and lies antipodally on the opposite side of Earth from the North Pole, at a distance of 12,430 miles (20,004 km) in all directions. Situated on the continent of Antarctica, it is the site of the United States Amundsen–Scott South Pole Station, which was established in 1956 and has been permanently staffed since that year. The Geographic South Pole is distinct from the South Magnetic Pole, the position of which is defined based on Earth's magnetic field. The South Pole is at the centre of the Southern Hemisphere. Geography For most purposes, the Geographic South Pole is defined as the southern point of the two points where Earth's axis of rotation intersects its surface (the other being the Geographic North Pole). However, Earth's axis of rotat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
