Cape Roquemaurel
Cape Roquemaurel () is a prominent rocky Antarctic headland at the east side of the entrance to Bone Bay, on the north side of Trinity Peninsula. Discovered by a French expedition, 1837–40, under Captain Jules Dumont d'Urville, and named by him for Lieutenant Gaston de Roquemaurel, second-in-command of the expedition ship Astrolabe An astrolabe ( grc, ἀστρολάβος ; ar, ٱلأَسْطُرلاب ; persian, ستارهیاب ) is an ancient astronomical instrument that was a handheld model of the universe.

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] |
Headland
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosion ... [...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, alth ...

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 taug ...

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 ...
