Thunder Glacier (Antarctica)
Thunder Glacier () is a through glacier, 4 nautical miles (7 km) long, which extends in an east–west direction across Wiencke Island between Sierra DuFief and the Wall Range, in the Palmer Archipelago. Probably known since the discovery of Wiencke Island by the Belgian Antarctic Expedition in 1898. Charted in 1944 by the Falkland Islands Dependencies Survey (FIDS), and so named by them because a survey party was nearly overwhelmed there by an avalanche.

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] |
Palmer Archipelago
Palmer Archipelago, also known as Antarctic Archipelago, Archipiélago Palmer, Antarktiske Arkipel or Palmer Inseln, is a group of islands off the northwestern coast of the Antarctic Peninsula. It extends from Tower Island in the north to Anvers Island in the south. It is separated by the Gerlache and Bismarck straits from the Antarctic Peninsula and Wilhelm Archipelago, respectively. Palmer Archipelago is located at . History Adrien de Gerlache, leader of the Belgian Antarctic Expedition (1897–1899), discovered the archipelago in 1898. He named it Archipelago Palmer for American Captain Nathaniel Palmer, who navigated these waters in 1820.

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.

Wiencke Island
Wiencke Island is an island long and from wide, about in area, the southernmost of the major islands of the Palmer Archipelago, lying between Anvers Island to its north across the Neumayer Channel and the west coast of the Antarctic Peninsula to its east across the Gerlache Strait. Description The rocky island is mostly covered by glaciers, snow and ice. Some small rocky beaches lie on the western and northern sides of the island. There, some grasses, moss and lichens can be found. There are three mountain ridges, with Nemo Peak (Antarctica), Nemo Peak, high, to the north-west; Nipple Peak to the north-east; and Luigi Peak, high, to the south-west. Luigi Peak is the island's summit, despite it never having been completely surveyed. Wiencke's northernmost point is Cape Astrup, a bold, dark-colored bluff discovered by the Belgian Antarctic Expedition, 1897–99. It was named by Adrien de Gerlache for Eivind Astrup, Norway, Norwegian Arctic explorer and member of Robert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra DuFief
The Sierra DuFief () is a mountain range 4 nautical miles (7 km) long with numerous sharp peaks, the highest at , extending in a northeast–southwest direction in the south part of Wiencke Island, in the Palmer Archipelago. It was discovered by the Belgian Antarctic Expedition, 1897–99, and named by Gerlache Baron Adrien Victor Joseph de Gerlache de Gomery (; 2 August 1866 – 4 December 1934) was a Belgian officer in the Belgian Royal Navy who led the Belgian Antarctic Expedition of 1897–99.

Belgian Antarctic Expedition
The Belgian Antarctic Expedition of 1897–1899 was the first expedition to winter in the Antarctic region. Led by Adrien de Gerlache de Gomery aboard the RV ''Belgica'', it was the first Belgian Antarctic expedition and is considered the first expedition of the Heroic Age of Antarctic Exploration. Among its members were Frederick Cook and Roald Amundsen, explorers who would later attempt the respective conquests of the North and South Poles. Preparation and surveying In 1896, after a period of intensive lobbying, Adrien Victor Joseph de Gerlache de Gomery purchased the Norwegian-built whaling ship ''Patria'', which, following an extensive refit, he renamed . Gerlache had worked together with the Geographical Society of Brussels to organize a national subscription, but was able to outfit his expedition only after the Belgian government voted in favor of two large subsidies, making it a state-supported undertaking. With a multinational crew that included Roald Amundsen from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

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 ...
