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 (15 July 1867 – 16 September 1936), born in Neuilly-sur-Seine, was a French scientist, medical doctor and polar scientist. His father was the neurologist Jean-Martin Charcot (1825–1893). Life Jean-Ba ... (1867–1936). The US Advisory Committee for Undersea Features (ACUF) confirmed the designation in June 1988.

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 60° S latitude and encircling Antarctica. With a size of , it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian oceans but larger than the Arctic Ocean. Over the past 30 years, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem. By way of his voyages in the 1770s, James Cook proved that waters encompassed the southern latitudes of the globe. Since then, geographers have disagreed on the Southern Ocean's northern boundary or even existence, considering the waters as various parts of the Pacific, Atlantic, and Indian oceans, instead. However, according to Commodore John Leech of the International Hydrographic Organization (IHO), recent oceanographic research has discovered the importance of Southern ...

Ellsworth Land
Ellsworth Land is a portion of the Antarctic continent bounded on the west by Marie Byrd Land, on the north by Bellingshausen Sea, on the northeast by the base of 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 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, Jones, Behrendt, Hauberg, Merrick, Sweeney and Scaife Mountains. This land lies near the center of the area traversed by American explorer Lincoln Ellsworth on an airplane flight during November–December 1935. It was named for him by the Advisory Committee on Antarct ... [...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 sands speeds towards the foot of the slope, until the current slows. The decreasing current, having a reduced ability to transport sediments, deposits the grains it carries, thus creating a su ...

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 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''). In the south are, from west to east, Eights Coast, Bryan Coast and English Coast (west part) of West 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. It takes its name from Admiral Thaddeus Bellingshausen, who explored in the area in 1821. In the late Pliocene 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 South Pacific Ocean South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Baptiste Charcot
Jean-Baptiste-Étienne-Auguste Charcot (15 July 1867 – 16 September 1936), born in Neuilly-sur-Seine, was a French scientist, medical doctor and polar scientist. His father was the neurologist Jean-Martin Charcot (1825–1893). 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 father, Jean-Martin Charcot. anhere./ref> He named Hugo Island after Victor Hugo, the grandfather of his wife, Jeanne Hugo.
