Casy Island
Coupvent Point () is a point, with several off-lying rocks, projecting north from Trinity Peninsula, southwest of Lafarge Rocks. Location Coupvent Point is near the east end of the north shore of Trinity Peninsula, which itself is the tip of the Antarctic Peninsula. It faces the Bransfield Strait. It is east of the Duroch Islands and Schmidt Peninsula, north of the Mott Snowfield and west of Caleta Thornton and Prime Head. Nomad Rock, Lafarge Rocks and Casy Island are north of the point. Name The name "Roche Coupvent" (Coupvent Rock) was given by Captain Jules Dumont d'Urville to a feature in the vicinity. The present name revives the d'Urville naming, given for August Coupvent-Desbois, an officer on the '' Zélée'' and later the ''Astrolabe''. Nearby features Nearby features, from west to east, include: Kevin Islands . A cluster of small islands and rocks which lie close to the northern coast of Trinity Peninsula, midway between Halpern Point and Coupvent Point. Nam ...

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 ...

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 ...

Bransfield Strait
Bransfield Strait or Fleet Sea ( es, Estrecho de Bransfield, Mar de la Flota) is a body of water about wide extending for in a general northeast – southwest direction between the South Shetland Islands and the Antarctic Peninsula. History The strait was named in about 1825 by James Weddell, Master, Royal Navy, for Edward Bransfield, Master, RN, who charted the South Shetland Islands in 1820. It is called ''Mar de la Flota'' by Argentina. On 23 November 2007, the MS ''Explorer'' struck an iceberg and sank in the strait; all 154 passengers were rescued and no injuries were reported. Description The undersea trough through the strait is known as Bransfield Trough (). The basin is about 400 km long and 2 km deep, between the South Shetland Island Arc and the Antarctic Peninsula. It was formed by rifting behind the islands, which began about 4 million years ago. Ongoing rifting has caused recent earthquakes and volcanism. The Strait hosts a chain of submerged seam ...

Schmidt Peninsula (Antarctica)
Schmidt Peninsula () is a small peninsula connected by a low isthmus to Cape Legoupil, Trinity Peninsula. Its western extremity is Bahamonde Point. The peninsula was named by the Chilean Antarctic Expedition of 1947-48 for Captain Hugo Schmidt Prado, Chilean Army The Chilean Army ( es, Ejército de Chile) is the land arm of the Military of Chile. This 80,000-person army (9,200 of which are conscripts) is organized into six divisions, a special operations brigade and an air brigade.

Prime Head
A prime number (or a prime) is a natural number greater than 1 that is not a Product (mathematics), product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, or , involve 5 itself. However, 4 is composite because it is a product (2 × 2) in which both numbers are smaller than 4. Primes are central in number theory because of the fundamental theorem of arithmetic: every natural number greater than 1 is either a prime itself or can be factorization, factorized as a product of primes that is unique up to their order. The property of being prime is called primality. A simple but slow method of checking the primality of a given number n, called trial division, tests whether n is a multiple of any integer between 2 and \sqrt. Faster algorithms include the Miller–Rabin primality test, which is fast but has a small chance of error, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jules Dumont D'Urville
Jules Sébastien César Dumont d'Urville (; 23 May 1790 – 8 May 1842) was a French explorer and naval officer who explored the south and western Pacific, Australia, New Zealand, and Antarctica. As a botanist and cartographer, he gave his name to several seaweeds, plants and shrubs, and places such as d'Urville Island in New Zealand. Childhood Dumont was born at Condé-sur-Noireau in Lower Normandy. His father, Gabriel Charles François Dumont, sieur d’Urville (1728–1796), Bailiff of Condé-sur-Noireau, was, like his ancestors, responsible to the court of Condé. His mother Jeanne Françoise Victoire Julie (1754–1832) came from Croisilles, Calvados, and was a rigid and formal woman from an ancient family of the rural nobility of Lower Normandy. The child was weak and often sickly. After the death of his father when he was six, his mother's brother, the Abbot of Croisilles, played the part of his father and from 1798 took charge of his education. The Abbot taugh ...

French Gunboat Zélée
''Zélée'' was a ''Surprise''-class gunboat of the French Navy. Designed for use overseas, she was used largely in the French colonies in Indochina and the Pacific. Assigned to patrol the waters off Tahiti at the start of World War I, she was sunk before scuttling could be completed during the Bombardment of Papeete on 22 September 1914. Service Present at Papeete during a devastating hurricane in February 1906, ''Zélée''s commander was asked to assist with rescue efforts on the quarantine island of Motauta, but refused due to the high risk involved. Instead he lent the island's station master an open boat and left him with the task of finding men to man it. At the outbreak of World War I, ''Zélée'' was stationed at Papeete and took part in the first French naval action of the war. The German cargo ship ''Walkure'' had been loading a cargo of phosphates at Makatea, an island from Tahiti. ''Zélée'' approached her, raised the French flag, and demanded her surrender. The Ger ...

French Ship Astrolabe (1811)
''Astrolabe'' was originally a horse-transport barge converted into an exploration ship of the French Navy. Originally named ''Coquille'', she is famous for her travels with Jules Dumont d'Urville. The name derives from an early navigational instrument, the astrolabe, a precursor to the sextant. Career Voyage under the command of Louis Isidore Duperrey Louis-Isidore Duperrey commanded ''Coquille'' on its circumnavigation of the earth (1822–1825) with Jules Dumont d'Urville as second. René-Primevère Lesson also travelled on ''Coquille'' as a naval doctor and naturalist. On their return in March 1825, Lesson and Dumont brought back to France an imposing collection of animals and plants collected on the Falkland Islands, on the coasts of Chile and Peru, in the archipelagos of the Pacific and New Zealand, New Guinea and Australia. During the voyage the ship spent two weeks in the Bay of Islands in the north of New Zealand in 1824. The vessel arrived in Kosrae where Duperrey ...

Cape Legoupil
Cape Legoupil is a cape at the northeast side of the entrance to Huon Bay, Trinity Peninsula, Antarctica, terminating in Schmidt Peninsula. It was discovered by a French expedition under Captain Jules Dumont d'Urville, 1837–40, and named for artist Ernest Goupil, who died on the expedition. The incorrect form Legoupil has been used so extensively that in this special case it is accepted. It is the site of the Chilean research station Base General Bernardo O'Higgins Riquelme Base General Bernardo O'Higgins Riquelme, also Base Libertador General Bernardo O'Higgins Riquelme, or shortly Bernardo O'Higgins, named after Bernardo O'Higgins, is a permanently staffed Chilean research station in Antarctica and the capital of ....
