Beaver Glacier (Ross Ice Shelf)
Beaver Glacier () is a glacier, long, draining the coastal mountains of the Queen Alexandra Range just northwest of Mount Fox and entering the Ross Ice Shelf at McCann Point. It was named by the New Zealand Geological Survey Antarctic Expedition (1959–60) after the Beaver aircraft ''City of Auckland'', which crashed in this area in January 1960.

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

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 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 located in the east of the Ross Sea. The ice shelf is named after 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 the original U.S. Antarctic Gazetteer. In Januar ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Queen Alexandra Range
The Queen Alexandra Range is a major mountain range of the Transantarctic Mountains System, located in the Ross Dependency region of Antarctica. It is about long, bordering the entire western side of Beardmore Glacier from the Polar Plateau to the Ross Ice Shelf. Alternate names for this range include Alexandra Mountains, Alexandra Range and Königin Alexandra Gebirge. The highest peak of the range is Mount Kirkpatrick at . Other peaks in the range include Mount Dickerson (4,120 m). Discovery This mountain range was discovered on the journey toward the South Pole by the British Antarctic Expedition, and was named by Ernest Shackleton for Queen consort Alexandra of the United Kingdom. Shackleton and his men, and a later expedition headed by Robert Falcon Scott, both collected rock samples from the range that contained fossils. The discovery that multicellular life forms had lived so close to the South Pole was an additional piece of evidence that accompanied the publicatio ...

McCann Point
Morris Heights () are a relatively smooth ice-covered heights, forming a peninsula-like divide between Beaver Glacier and King Glacier at the north end of the Queen Alexandra Range. Name Morris Heights were named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant Clarence T. Morris, United States Navy, aerology officer on the staff of the Commander, U.S. Naval Support Force, Antarctica, 1962 and 1963. Location Morris Heights are in the northeast of the Queen Alexandra Range between Beaver Glacier and King Glacier. Mount Gunner rises from the south of the heights. McCann Point is at the north end. Nearby features include Mount Nickerson and Yeates Bluff on the peninsula to the northwest at the mouth of Lennox-King Glacier, Mount Ida, Granite Pillars, Cape Allen, The Gateway and Mount Hope on the peninsula to the southeast at the mouth of Beardmore Glacier, and Mount Fox and Mount F.

De Havilland Canada DHC-2 Beaver
The de Havilland Canada DHC-2 Beaver is a single-engined high-wing propeller-driven short takeoff and landing (STOL) aircraft developed and manufactured by de Havilland Canada. It has been primarily operated as a bush plane and has been used for a wide variety of utility roles, such as cargo and passenger hauling, aerial application (crop dusting and aerial topdressing), and civil aviation duties. Shortly after the end of the Second World War, de Havilland Canada decided to orient itself towards civilian operators. Based on feedback from pilots, the company decided that the envisioned aircraft should have excellent STOL performance, all-metal construction, and accommodate many features sought by the operators of bush planes. On 16 August 1947, the maiden flight of the aircraft, which had received the designation ''DHC-2 Beaver'', took place. In April 1948, the first production aircraft was delivered to the Ontario Department of Lands and Forests. A Royal New Zealand Air Forc ...

List Of Glaciers In The Antarctic
There are many glaciers in the Antarctic. This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice. The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. Ice streams are a type of glacier and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System).

Glaciology
Glaciology (; ) is the scientific study of glaciers, or more generally ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology. The impact of glaciers on people includes the fields of human geography and anthropology. The discoveries of water ice on the Moon, Mars, Europa and Pluto add an extraterrestrial component to the field, which is referred to as "astroglaciology". Overview A glacier is an extended mass of ice formed from snow falling and accumulating over a long period of time; glaciers move very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers. Areas of study within glaciology include glacial history and the reconstruction of past glaciation. A glaciologist is a person who studies glaciers. A glacial geologist ...
