Archer Point
Matusevich Glacier () is a broad glacier about long, with a well developed glacier tongue, flowing to the coast of East Antarctica between the Lazarev Mountains and the northwestern extremity of the Wilson Hills. Discovery and naming The region was photographed by U.S. Navy Operation Highjump, 1946–47, the Soviet Antarctic Expedition, 1957–58, and the Australian National Antarctic Research Expeditions, 1959 and 1962. It was named by the Soviet expedition after Nikolai Nikolayevich Matusevich, a Soviet hydrographer and surveyor. Glaciology The glacier flows toward the coast of East Antarctica, pushing through a channel between the Lazarev Mountains and the north-western tip of the Wilson terrain. Constrained by surrounding rocks, the river of ice holds together. But stresses resulting from the glacier's movement make deep crevasses, or cracks, in the ice. After passing through the channel, the glacier has room to spread out as it floats on the ocean. The expanded area and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacier Morphology
Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. Types of glaciers can range from massive ice sheets, such as the Greenland ice sheet, to small cirque glaciers found perched on mountain tops. Glaciers can be grouped into two main categories: * Ice flow is constrained by the underlying bedrock topography * Ice flow is unrestricted by surrounding topography Unconstrained Glaciers Ice sheets and ice caps Ice sheets and ice caps cover the largest areas of land in comparison to other glaciers, and their ice is unconstrained by the underlying topography. They are the largest glacial ice formations and hold the vast majority of the world's fresh water. Ice sheets Ice sheets are the largest form of glacial formation. They are continent-sized ice masses that span areas over . They are dome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Dalton
Wilson Hills () is a group of scattered hills, nunataks and ridges that extend northwest–southeast about between Matusevich Glacier and Pryor Glacier in Antarctica. Discovery and naming The Wilson Hills were discovered by Lieutenant Harry Pennell, Royal Navy, on the Terra Nova Expedition in February 1911 during Robert Falcon Scott's last expedition. They were named after Edward Adrian Wilson, a zoologist with the expedition, who perished with Scott on the return journey from the South Pole. Location Features of the Wilson Hills along the east of the Matusevich Glacier include, from south to north, Mount Dalton, Thompson Peak, Ringgold Knoll and Mount Archer. Other inland features include, from northwest to southeast, Celestial Peak, Governor Mountain, Pope Mountain, Jones Nunatak, Mount Schutz, Stevenson Bluff, Mount Steele, Mount Ellery, Poorman Peak and Mount Perez. Features of the extreme south include Mount Gorton, Basilica Peak and Mount Send. Scattered peaks and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phillip Law
Phillip Garth Law, AC, CBE, FAA, FTSE (21 April 1912 – 28 February 2010) was an Australian scientist and explorer who served as director of Australian National Antarctic Research Expeditions (ANARE) from 1949 to 1966. Early life Law was born in Tallangatta, Victoria, the second of six children of Arthur and Lily Law. One of his younger sisters was the traveller and writer Wendy Law Suart. After attending Hamilton High School, he taught in secondary schools, including Melbourne High School where he taught physics and boxing, while studying part-time at the University of Melbourne, earning an MSc in 1941. He was the Melbourne University lightweight boxing champion and also lectured in physics there from 1943 to 1948. During the Second World War he enlisted in the RAAF, though the university physics department, which was involved in weapons research, insisted that he continue his work there. He did however manage to visit the battle areas of New Guinea on a four-month sci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magga Dan
The Buddhist path (''marga'') to liberation, also referred to as awakening, is described in a wide variety of ways. The classical one is the Noble Eightfold Path, which is only one of several summaries presented in the Sutta Pitaka. A number of other paths to liberation exist within various Buddhist traditions and theology. Early Buddhism There are various expositions of the path to liberation in the Early Buddhist texts, the following examples are drawn from the Pali Nikayas. The Noble Eightfold Path The Noble Eightfold Path is widely known as ''the'' description of the Buddhist path. In the Sutta Pitaka it is summed up as follows: Alternate sequences in the Pali Nikayas Alternate, and possibly older, sequences of the stages on the Buddhist path to liberation, can be found throughout the Pali Canon. Tevijja Sutta A standard sequence of developments can be found in the Nikayas, which may predate the more stylised four noble truths. For example the Tevijja Sutta verse 40� ...

Glacier Tongue
An ice tongue or glacier tongue exists when there is a narrow floating part of a glacier that extends out into a body of water beyond the glacier's lowest contact with the Earth's crust. An ice tongue forms when a glacier that is confined by a valley moves very rapidly out into a lake or ocean, relative to other ice along the coastline. When such ice surges past adjacent coastal ice, the boundary experiences physical forces described as "shearing". Ice tongues can gain mass from water freezing at their base, by snow falling on top of them, or by additional surges from the main glacier. Mass is then lost by calving or by melting. Icebergs are often formed when ice tongues break off in part or wholly from the main glacier. A few examples of ice tongues are the Erebus Glacier Tongue, Drygalski Ice Tongue The Drygalski Ice Tongue, Drygalski Barrier, or Drygalski Glacier Tongue is a glacier in Antarctica, on the Scott Coast, in the northern McMurdo Sound of Ross Dependency, ...

Mount Archer (Antarctica)
Mount Archer is a rock peak immediately south of Archer Point on the west side of Harald Bay in Antarctica. The peak was mapped from aerial photos taken in February 1959 by the ANARE (Australian National Antarctic Research Expeditions) led by Phillip Law. It is named after Archer Point. Important Bird Area A 204 ha site comprising the lower eastern extremity of Mount Archer and the whole of neighbouring Kartografov Island, as well as the intervening marine area, has been designated an Important Bird Area (IBA) by BirdLife International because it supports about 21,000 breeding pairs of Adélie penguin The Adélie penguin (''Pygoscelis adeliae'') is a species of penguin common along the entire coast of the Antarctic continent, which is the only place where it is found. It is the most widespread penguin species, and, along with the emperor peng ...s, as estimated by 2012 satellite imagery. References External links * Important Bird Areas of Antarctica Penguin co ...

Soviet Hydrographic Service
The Russian Hydrographic Service, full current official name Department of Navigation and Oceanography of the Ministry of Defence of the Russian Federation, is Russia's hydrographic office, with responsibility to facilitate navigation, performing hydrographic surveys and publishing nautical charts. Since the Russian state is of such a vast size and nature that it includes many different seas, long and indented coastlines and a great number of islands, as well as a complex system of waterways and lakes, surveying has been an indispensable activity for the Russian Navy since its modernization at the time of Czar Peter the Great in the 17th century. The hydrographic service has been historically attached to the Russian Navy and the agents and supervisors of hydrographic works have been largely naval officers throughout its history. Russia is a member of the International Hydrographic Organization. Competences and functions Despite having undergone a number of name changes along its ...

East Antarctica
East Antarctica, also called Greater Antarctica, constitutes the majority (two-thirds) of the Antarctic continent, lying primarily in the Eastern Hemisphere south of the Indian Ocean, and separated from West Antarctica by the Transantarctic Mountains. It is generally greater in elevation than West Antarctica, and includes the Gamburtsev Mountain Range in the center. The geographic South Pole is located within East Antarctica. Apart from small areas of the coast, East Antarctica is permanently covered by ice and it has relatively low biodiversity, with only a small number of species of terrestrial plants, animals, algae, and lichens. The coasts are the breeding ground for various seabirds and penguins, and the leopard seal, Weddell seal, elephant seal, crabeater seal and Ross seal breed on the surrounding pack ice in summer. Location and description Almost completely covered in thick, permanent ice, East Antarctica comprises Coats Land, Queen Maud Land, Enderby Land, ...
