Matusevich Glacier
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. Geography 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 the jostling of ocean waves prompts the ice to break apart, which it often does along existing crevasses. Matusevich Glacier does not drain a significant amount of ice off of the Antarctic continent, so the glacier's advances and retreats lack global significance. Like other Antarctic glaciers, however, Matusevich helps glaciolog ... [...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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 scie ... [...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 is a long and narrow sheet of ice projecting out from the coastline. An ice tongue forms when a valley glacier moves very rapidly (relative to surrounding ice) out into the ocean or a lake. They can gain mass from water freezing at their base, or by snow falling on top of them. Mass is then lost by calving or by melting. Ice tongues can range in length from to . Icebergs are often formed when ice tongues break off in part or wholly from the main glacier. Two examples of ice tongues are the Erebus Ice Tongue and the 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, north of Ross Island.

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 ( rus, Управление навигации и океанографии Министерства обороны Российской Федерации), 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 ...

Australian National Antarctic Research Expeditions
The Australian National Antarctic Research Expeditions (ANARE ) is the historical name for the Australian Antarctic Program (AAp) administered for Australia by the Australian Antarctic Division (AAD). History Australia has had a long involvement in south polar regions since as early as Douglas Mawson's Australasian Antarctic Expedition in 1911. Further Australian exploration of the Antarctic continent was conducted during the British Australian and New Zealand Antarctic Research Expedition (BANZARE), which was conducted over the years 1929–1931. The Australian National Antarctic Research Expeditions were established in 1947 with expeditions to Macquarie Island and Heard Island. In 1948 the Australian Antarctic Division (AAD) was established to administer the expedition program. ANARE Name The name ANARE fell out of official use in the early 2000s. However current and former Australian Antarctic expeditioners continue to use the term informally as a means of identifica ...

East Antarctica
East Antarctica, also called Greater Antarctica, constitutes the majority (two-thirds) of the Antarctic continent, lying on the Indian Ocean side of the continent, separated from West Antarctica by the Transantarctic Mountains. It lies almost entirely within the Eastern Hemisphere and its name has been accepted for more than a century. It is generally higher 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.
