Bailey Ice Stream
Bailey Ice Stream () is an ice stream on the northern margin of the Theron Mountains, flowing west-southwest to the Filchner Ice Shelf. It was named by the UK Antarctic Place-Names Committee after Jeremy Thomas Bailey (1941–65), a British Antarctic Survey glaciologist, who with two companions died in a crevasse accident during a radio echo sounding traverse inland from Halley Station on 12 October 1965. On an earlier traverse in April 1965, Bailey sounded the upper portion of this feature.

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 ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Filchner Ice Shelf
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.

Ice Stream
An ice stream is a region of fast-moving ice within an ice sheet. It is a type of glacier, a body of ice that moves under its own weight. They can move upwards of a year, and can be up to in width, and hundreds of kilometers in length. They tend to be about deep at the thickest, and constitute the majority of the ice that leaves the sheet. In Antarctica, the ice streams account for approximately 90% of the sheet's mass loss per year, and approximately 50% of the mass loss in Greenland. The shear forces cause deformation and recrystallization that drive the movement, this movement then causes topographic lows and valleys to form after all of the material in the ice sheet has been discharged. Sediment also plays an important role in flow velocity, the softer and more easily deformed the sediment present, the easier it is for flow velocity to be higher. Most ice streams contain a layer of water at the bottom, which lubricates flow and acts to increase speed. Mechanics Ice st ...

Theron Mountains
The Theron Mountains () are a group of mountains, extending in a NE-SW direction for and rising , on the eastern side of the Filchner Ice Shelf. They were first seen from the air in 1956 by the Commonwealth Trans-Antarctic Expedition The Commonwealth Trans-Antarctic Expedition (CTAE) of 1955–1958 was a Commonwealth-sponsored expedition that successfully completed the first overland crossing of Antarctica, via the South Pole. It was the first expedition to reach the South ... (CTAE) and named for the ''Theron'', the ship of the CTAE in 1955–56.

UK Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica.

British Antarctic 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 British Admiralty, Admiralty and the Secretary of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glaciologist
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 geologis ...

Crevasse
A crevasse is a deep crack, that forms in a glacier or ice sheet that can be a few inches across to over 40 feet. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. The resulting intensity of the shear stress causes a breakage along the faces. Description Crevasses often have vertical or near-vertical walls, which can then melt and create seracs, arches, and other ice formations. These walls sometimes expose layers that represent the glacier's stratigraphy. Crevasse size often depends upon the amount of liquid water present in the glacier. A crevasse may be as deep as 45 metres and as wide as 20 metres. by [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halley Station
Halley Research Station is a research facility in Antarctica on the Brunt Ice Shelf operated by the British Antarctic Survey (BAS). The base was established in 1956 to study the Earth's atmosphere. Measurements from Halley led to the discovery of the ozone hole in 1985. The current base is the sixth in a line of structures and includes design elements intended to overcome the challenge of building on a floating ice shelf without being buried and crushed by snow. , the base has been left unstaffed through winter since 2017, due to concerns over the propagation of an ice crack and how this might cut off the evacuation route in an emergency. The Halley Bay Important Bird Area with its emperor penguin colony lies in the general vicinity of the base. History Halley Bay base was founded in 1956, for the International Geophysical Year of 1957–1958, by an expedition from the Royal Society. The bay where the expedition decided to set up their base was named after the astronomer Ed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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).
