Murray Snowfield
Murray Snowfield () is a snowfield centered 2 nautical miles (3.7 km) south of Possession Bay in South Georgia. The name "John Murray-Gletscher" was given to a glacier flowing into the head of Possession Bay by members of the Second German Antarctic Expedition The Second German Antarctic Expedition of 1911–1913 was led by Wilhelm Filchner in the exploration ship . Its principal objective was to determine whether the Antarctic continent comprised a single landmass rather than separated elements, and i ..., 1911–12. The SGS, 1955–56, reported that there is no true glacier in this position, but that the nearby snowfield requires a name.

Snow Field
A snow field, snowfield or neve is an accumulation of permanent snow and ice, typically found above the snow line, normally in mountainous and glacial terrain. Glaciers originate in snowfields. The lower end of a glacier is usually free from snow and névé in summer. In the upper end and above the upper boundary of a glacier, the snow field is an ice field An ice field (also spelled icefield) is a mass of interconnected valley glaciers (also called mountain glaciers or alpine glaciers) on a mountain mass with protruding rock ridges or summits. They are often found in the colder climates and highe ... covered with snow. The glacier upper boundary, where it emerges from under a snow field, is ill-defined because of gradual transition.Thomas Chrowder Chamberlin, Rollin D.

Possession Bay
Possession Bay is a bay wide on the north coast of South Georgia, an island in the southern Atlantic Ocean. It recedes southwest for , and is separated from Cook Bay to the north by Black Head promontory. It is connected to King Haakon Bay by Shackleton Gap, a mountain pass. Geography Several features in and around Possession Bay have been charted by various Antarctic expeditions. Black Head is a dark, rugged promontory, high, which separates Possession Bay from Cook Bay, to the north. At the head of the bay, Inner Reef extends from the headland Adventure Point on the west side of the bay to Brown Point on the east side. Just south of Adventure Point is Brighton Beach, which extends to Zero Point. Zero Point sits at the north side of Assistance Bay, a small bay within the larger Possession Bay. On the east side of the bay, Alert Point marks the mouth of Purvis Glacier. Outer Moraine Reef extends from Alert Point to Steep Point. Brown Point sits between Steep Point an ...

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.

Wilhelm Filchner
Wilhelm Filchner (13 September 1877 – 7 May 1957) was a German army officer, scientist and explorer. He conducted several surveys and scientific investigations in China, Tibet and surrounding regions, and led the Second German Antarctic Expedition, 1911–13. As a young military officer, Filchner gained an early reputation for dash and daring, following his travel exploits in Russia and the Pamir Mountains range. After further technical studies, he developed expertise in geography and geophysics, before leading a major scientific survey in Tibet and western China in 1903–05. In 1909 he was appointed to organise and lead the forthcoming German expedition to the Antarctic, with both scientific and geographical objectives involving extensive exploration of the continent's interior. During the expedition his ship became trapped in the Weddell Sea ice, drifting for eight months and preventing Filchner from establishing a land base, thus failing in its main objective.

Snow Fields Of Antarctica
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
