Avery Plateau
Avery Plateau () is an ice-covered plateau, about long and rising to about , midway between Loubet Coast and Foyn Coast in Graham Land, Antarctica. It borders Hemimont Plateau on the south and Bruce Plateau on the north. The first sighting of this plateau is not certain, but it was presumably seen in January and February 1909 by members of the French Antarctic Expedition under Jean-Baptiste Charcot from various positions in the Matha Strait. It was surveyed in 1946–47 by the Falkland Islands Dependencies Survey, and named by the UK Antarctic Place-Names Committee (1955) after Captain George Avery, master of the cutter ''Lively'', who, with Captain John Biscoe in the brig ''Tula'', approached this part of the Antarctic Peninsula in February 1832.

Cutter (boat)
A cutter is a type of watercraft. The term has several meanings. It can apply to the rig (or sailplan) of a sailing vessel (but with regional differences in definition), to a governmental enforcement agency vessel (such as a coast guard or border force cutter), to a type of ship's boat which can be used under sail or oars, or, historically, to a type of fast-sailing vessel introduced in the 18th century, some of which were used as small warships. As a sailing rig, a cutter is a single-masted boat, with two or more headsails. On the eastern side of the Atlantic, the two headsails on a single mast is the fullest extent of the modern definition. In U.S. waters, a greater level of complexity applies, with the placement of the mast and the rigging details of the bowsprit taken into account so a boat with two headsails may be classed as a sloop. Government agencies use the term "cutter" for vessels employed in patrolling their territorial waters and other enforcement activities. Th ...

Plateaus Of Antarctica
In geology and physical geography, a plateau (; ; ), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wide ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, Plate tectonics movements and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. The Columbia Plateau in the north-western United States is an example. They may be formed by upwelling of volcanic magma or extrusion of lava. The un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forbidden Plateau (Antarctica)
The Forbidden Plateau () is a long, narrow plateau extending southwestward from Charlotte Bay to Flandres Bay in Graham Land. It borders Bruce Plateau on the south and Foster Plateau on the north. The feature was mapped by the Falkland Islands Dependencies Survey (FIDS) from photos taken by Hunting Aerosurveys Ltd. in 1956–57. Its name was picked by the UK Antarctic Place-names Committee (UK-APC) because all attempts to reach the plateau failed until it was finally traversed by Falkland Islands Dependencies Survey (FIDS) members in 1957.

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.

Louis Philippe Plateau
Louis Philippe Plateau () is a plateau, about long and wide, which rises to and occupies the central part of Trinity Peninsula, Antarctica, between Russell West Glacier and Windy Gap. This application of the name, recommended by the UK Antarctic Place-Names Committee in 1948, commemorates Captain Jules Dumont d'Urville's 1838 exploration of the Trinity Peninsula area, which he had named "Terre Louis Philippe," after Louis Philippe I, the King of France at the time.

Antarctic Peninsula
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica. The Antarctic Peninsula is part of the larger peninsula of West Antarctica, protruding from a line between Cape Adams (Weddell Sea) and a point on the mainland south of the Eklund Islands. Beneath the ice sheet that covers it, the Antarctic Peninsula consists of a string of bedrock islands; these are separated by deep channels whose bottoms lie at depths considerably below current sea level. They are joined by a grounded ice sheet. Tierra del Fuego, the southernmost tip of South America, is about away across the Drake Passage. The Antarctic Peninsula is in area and 80% ice-covered. The marine ecosystem around the western continental shelf of the Antarctic Peninsula (WAP) has been subjected to rapid climate change. Over the past 50 ...

Brig
A brig is a type of sailing vessel defined by its rig: two masts which are both square rig, square-rigged. Brigs originated in the second half of the 18th century and were a common type of smaller merchant vessel or warship from then until the latter part of the 19th century. In commercial use, they were gradually replaced by fore-and-aft rigged vessels such as schooners, as owners sought to reduce crew costs by having rigs that could be handled by fewer men. In Royal Navy use, brigs were retained for training use when the battle fleets consisted almost entirely of iron-hulled steamships. Brigs were prominent in the coasting coal trade of British waters. 4,395 voyages to London with coal were recorded in 1795. With an average of eight or nine trips per year for one vessel, that is a fleet of over 500 colliers trading to London alone. Other ports and coastal communities were also be served by colliers trading to Britain's coal ports. In the first half of the 19th century, the va ...

John Biscoe
John Biscoe (28 April 1794 – 1843) was an English mariner and explorer who commanded the first expedition known to have sighted the areas named Enderby Land and Graham Land along the coast of Antarctica. The expedition also found a number of islands in the vicinity of Graham Land, including the Biscoe Islands that were named after him. Early life Biscoe was born in Enfield, Middlesex, England. In March 1812, aged seventeen, he joined the Royal Navy and served during the 1812–1815 war against the United States. By the time of his discharge in 1815, he had become a justice Master. Thereafter he sailed on board merchant shipping as a mate or master, mostly to the East or West Indies. Southern Ocean expedition, 1830–1833 In 1830, the whaling company Samuel Enderby & Sons appointed Biscoe master of the brig ''Tula'' and leader of an expedition to find new sealing grounds in the Southern Ocean. Accompanied by the cutter ''Lively'', the ''Tula'' left London and by December ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
