Traub Glacier
Traub Glacier is a glacier on Greenwich Island in the South Shetland Islands, Antarctica extending 2.5 km in northwest-southeast direction and 4 km in southwest-northeast direction and draining the east slopes of Dryanovo Heights to flow eastwards into Discovery Bay. The feature was named by the 1947 Chilean Antarctic Expedition after Lieutenant Norberto Traub, a member of the expedition. Location The glacier is centred at (Bulgarian mapping in 2005 and 2009).

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] |
Greenwich Island
Greenwich Island (variant historical names ''Sartorius Island'', ''Berezina Island'') is an island long and from (average ) wide, lying between Robert Island and Livingston Island in the South Shetland Islands. Surface area . The name Greenwich Island dates back to at least 1821 and is now established in international usage. The Chilean base Arturo Prat and the Ecuadorian base Pedro Vicente Maldonado are situated on the northeast and north coast of the island respectively. Chilean scientists have claimed that Amerinds visited the area, due to stone artifacts recovered from bottom-sampling operations off the island; however, the artefacts — two arrowheads — were later found to have been planted.

South Shetland Islands
The South Shetland Islands are a group of Antarctic islands with a total area of . They lie about north of the Antarctic Peninsula, and between southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes. The islands have been claimed by the United Kingdom since 1908 and as part of the British Antarctic Territory since 1962. They are also claimed by the governments of Chile (since 1940, as part of the Antártica Chilena province) and Argentina (since 1943, as part of Argentine Antarctica, Tierra del Fuego Province). Several countries maintain research stations on the islands. Most of them are situated on King George Island, benefitting from the airfield of the Chilean base Eduardo Frei. There are sixteen research stations in different parts of the islands, with Chilean stations being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discovery Bay (Antarctica)
Discovery Bay is a bay long and wide, indenting the north side of Greenwich Island, in the South Shetland Islands of Antarctica. It had been known to sealers in the area since about 1821. It was charted and named in 1935 by Discovery Investigations personnel on the ''Discovery II''. The Chilean Antarctic Expedition of 1947, under the command of Captain Federico Guesalaga Toro, decided to rename the name ''Bahía Chile'' as the site of Chile's first permanent Antarctic base, Base Soberanía, now Capitán Arturo Prat Base. Antarctic Specially Protected Area Two marine sites in the bay have collectively been designated Antarctic Specially Protected Area (ASPA) 144 (formerly SSSI 26), to protect the bay's benthic The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers.

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 ...
