Diplock Glacier
Diplock Glacier () is a narrow straight glacier, long, flowing eastward from Detroit Plateau, on Trinity Peninsula in Graham Land, into Prince Gustav Channel south of Alectoria Island. It is situated south of Marla Glacier and north of Zavera Snowfield. The feature was mapped from surveys by the Falkland Islands Dependencies Survey (1960–61), and was named by the UK Antarctic Place-Names Committee for Bramah Joseph Diplock, a British engineer who made considerable advances in the design of chain-track tractors (1885–1913).

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] |
Trinity Peninsula
Trinity Peninsula is the northernmost part of the Antarctic Peninsula. It extends northeastward for about 130 km (80 mi) to Cape Dubouzet from an imaginary line connecting Cape Kater on the north-west coast and Cape Longing on the south-east coast. Prime Head is the northernmost point of this peninsula. Some 20 kilometers southeast of Prime Head is Hope Bay with the year-round Argentinian Esperanza Base. History It was first sighted on 30 January 1820 by Edward Bransfield, Master, Royal Navy, immediately after his charting of the newly discovered South Shetland Islands nearby. In the century following the peninsula's discovery, chartmakers used various names (Trinity Land, Palmer Land, and Land of Louis Philippe) for this portion of it, each name having some historical merit. The recommended name derives from "Trinity Land", given by Bransfield during 1820 in likely recognition of the Corporation of Trinity House, Britain's historical maritime pilotage authority, altho ...

Prince Gustav Channel
The Prince Gustav Channel was named in 1903 after Crown Prince Gustav of Sweden (later King Gustav V) by Otto Nordenskiöld of the Swedish Antarctic Expedition. The channel is bounded on the west by the Antarctic Peninsula and on the east by James Ross Island. It is about long and ranges from wide. On 27 February 1995, the British Antarctic Survey (BAS) reported that an ice shelf formerly blocking the channel had disintegrated. This ice shelf had spanned approximately prior to its disintegration. In the area previously covered by the shelf, the channel's water depth is between . Between February and March 2000, scientists collected sediment cores 5 to 6 m in length from the ocean floor. Carbon dating of organic material found in the sediment layers suggested that for a period between 2,000 and 5,000 years ago, much of the channel was seasonally open water. While icebergs were able to navigate the channel, ice rafted debris was deposited within the sediment. Prince Gustav Ic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Detroit Plateau
Detroit Plateau () is a major interior plateau of Graham Land on the Antarctic Peninsula, with heights between . Its northeast limit is marked by the south wall of Russell West Glacier, from which it extends some in a general southwest direction to Herbert Plateau. The plateau was observed from the air by Sir Hubert Wilkins on a flight of December 20, 1928. Wilkins named it Detroit Aviation Society Plateau after the society which aided in the organizing of his expedition, but the shortened form of the original name is approved. The north and east sides of the plateau were charted by the Falkland Islands Dependencies Survey in 1946–47. Dinsmoor Glacier flows east from the south edge of Detroit Plateau.

Graham Land
Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, in which the name "Antarctic Peninsula" was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south. Graham Land is named after Sir James R. G. Graham, First Lord of the Admiralty at the time of John Biscoe's exploration of the west side of Graham Land in 1832. It is claimed by Argentina (as part of Argentine Antarctica), Britain (as part of the British Antarctic Territory) and Chile (as part of the Chilean Antarctic Territory). Graham Land is the closest part of Antarctica to South America. Thus it is the usual destination for small ships taking paying ...

Bramah Joseph Diplock
Bramah Joseph Diplock (27 April 1857 – 9 August 1918) was an English inventor who invented the pedrail wheel in 1899 and the pedrail chaintrack, a type of caterpillar track, in 1907. Diplock was born in Chelsea, London to Thomas Bramah Diplock, a coroner, and Eleanor Diplock. He died suddenly on the 9th August 1918 of brain hemorrhage at 21 Heathfield Close, Chiswick, aged 62. Diplock Glacier in Antarctica is named after him due to his contribution to the development of tracked vehicles. Inventions Diplock's first inventions were related to improving traction in geared locomotives (both road and rail) by driving all wheels, this presenting problems due to the need to steer the vehicle. His patents date back to 1893 when he was living in Falmouth, Cornwall. This desire for greater traction in road locomotives (traction engines) probably led directly to the pedrail system which he patented in 1899. In this design the continuously laid tracks contain rollers and the rails r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
