Charcot Fan
Charcot Fan () is a deep-sea formation in the Southern Ocean. It lies off the coast of the West Antarctic Ellsworth Land. The Charcot Fan is an abyssal fan specifically located between the Bellingshausen Plain and the continental shelf of the Bellingshausen Sea. It is named after the French polar explorer Jean-Baptiste Charcot Jean-Baptiste Étienne Auguste Charcot, better known in France as Commandant Charcot, (15 July 1867 in Neuilly-sur-Seine near Paris – 16 September 1936 at sea (30 miles north-west of Reykjavik, Iceland), was a French scientist, medical doctor ... (1867–1936). The US Advisory Committee for Undersea Features (ACUF) confirmed the designation in June 1988. References {{antarctica-geo-stub Geography of Antarctica ...

Southern Ocean
The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the world ocean, generally taken to be south of 60th parallel south, 60° S latitude and encircling Antarctica. With a size of , it is the second-smallest of the five principal oceanic divisions, smaller than the Pacific Ocean, Pacific, Atlantic Ocean, Atlantic and Indian Ocean, Indian oceans, and larger than the Arctic Ocean. The maximum depth of the Southern Ocean, using the definition that it lies south of 60th parallel, was surveyed by the Five Deeps Expedition in early February 2019. The expedition's multibeam sonar team identified the deepest point at 60° 28' 46"S, 025° 32' 32"W, with a depth of . The expedition leader and chief submersible pilot Victor Vescovo, has proposed naming this deepest point the "Factorian Deep", based on the name of the crewed submersible ''DSV Limiting Factor'', in which he successfully visited the bottom for the first time on February 3, 2019 ...

Ellsworth Land
Ellsworth Land is a portion of the Antarctica, Antarctic continent bounded on the west by Marie Byrd Land, on the north by the Bellingshausen Sea, on the northeast by the base of the Antarctic Peninsula, and on the east by the western margin of the Filchner–Ronne Ice Shelf. It extends between 103°24'W and 79°45'W. The area west of 90°W is unclaimed, the area between 84°W and 90°W is claimed by Antártica Chilena Province, Chile only, and the remainder by Chile and the United Kingdom as a part of the British Antarctic Territory. Eights Coast stretches between 103°24'W and 89°35'W, and Bryan Coast between 89°35'W and 79°45'W. It is largely a high ice plateau, but includes the Ellsworth Mountains and a number of scattered mountain groups: Hudson Mountains, Hudson, Jones Mountains, Jones, Behrendt Mountains, Behrendt, Hauberg Mountains, Hauberg, Merrick Mountains, Merrick, Sweeney Mountains, Sweeney and Scaife Mountains. This land lies near the center of the area traversed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abyssal Fan
Abyssal fans, also known as deep-sea fans, underwater deltas, and submarine fans, are underwater geological structures associated with large-scale sediment deposition and formed by turbidity currents. They can be thought of as an underwater version of alluvial fans and can vary dramatically in size, with widths from several kilometres to several thousands of kilometres. The largest is the Bengal Fan, followed by the Indus Fan, but major fans are also found at the outlet of the Amazon, Congo, Mississippi and elsewhere. Formation Abyssal (or submarine) fans are formed from turbidity currents. These currents begin when a geologic activity pushes sediments over the edge of a continental shelf and down the continental slope, creating an underwater landslide. A dense slurry of muds and sand Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is usually defined by its grain size. Sand grains are smaller than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bellingshausen Plain
Bellingshausen Plain (), also known as Bellinghausen Abyssal Plain, is an undersea plain parallel to the continental rise in the Bellingshausen Sea, named for Admiral Fabian Gottlieb von Bellingshausen, commander of the Russian Antarctic Expedition (1818–1821). The name was approved by the Advisory Committee for Undersea Features The United States Board on Geographic Names (BGN) is a Federal government of the United States, federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geogr ... in April 1974. References * Abyssal plains of the Southern Ocean {{marine-geo-stub ...

Bellingshausen Sea
The Bellingshausen Sea is an area along the west side of the Antarctic Peninsula between 57°18'W and 102°20'W, west of Alexander Island, east of Cape Flying Fish on Thurston Island, and south of Peter I Island (there the southern ''Vostokkysten''). The Bellingshausen Sea borders the Eights Coast, the Bryan Coast, and the west part of the English Coast in Antarctica. To the west of Cape Flying Fish it joins the Amundsen Sea. Bellingshausen Sea has an area of and reaches a maximum depth of . It contains the undersea plain Bellingshausen Plain. The Antarctic Slope Current (ASC) is thought to originate in the Bellingshausen Sea as the result of a density front at the shelf break, rather than being wind-driven. It takes its name from Fabian Gottlieb von Bellingshausen, who explored in the area in 1821. In the early Pleistocene Epoch, about 2.15 million years ago, the Eltanin asteroid (about 1-4 km in diameter) impacted at the edge of the Bellingshausen sea (at the Southern Oc ...

Jean-Baptiste Charcot
Jean-Baptiste Étienne Auguste Charcot, better known in France as Commandant Charcot, (15 July 1867 in Neuilly-sur-Seine near Paris – 16 September 1936 at sea (30 miles north-west of Reykjavik, Iceland), was a French scientist, medical doctor and polar scientist. His father was the neurologist Jean-Martin Charcot (1825–1893). As a sportsman, he was French rugby XV champion in 1896 and also won a double silver medal in sailing at the 1900 Summer Olympics. Life Jean-Baptiste Charcot was appointed leader of the French Antarctic Expedition with the ship ''Français'' exploring the west coast of Graham Land from 1904 until 1907. The expedition reached Adelaide Island in 1905 and took pictures of the Palmer Archipelago and Loubet Coast. From 1908 until 1910, another expedition followed with the ship '' Pourquoi Pas ?'', exploring the Bellingshausen Sea and the Amundsen Sea and discovering Loubet Land, Marguerite Bay, Mount Boland and Charcot Island, which was named after his ...
