Sobral Base
Sobral Scientific Base ( es, Base de Avanzada Científica de Ejército Alférez de Fragata Sobral, or simply ''Base Científica Sobral'' or ''Base Sobral'') was a permanent, all year-round and now only partially active Argentine Antarctic base and scientific research station named after Argentine polar explorer and scientist José María Sobral. It is located on the Filchner Ice Shelf. History Sobral was founded with the goal of asserting Argentine sovereignty over the area while providing a launch platform for that year's planned land expedition to the South Pole. The establishment of the base required over three months of continuous work done in a then barely-known region under extreme environmental circumstances. More than of equipment were transported by tractors over heavily cracked terrain that slowed and often halted the tracked vehicles and sleds. The settling team went across a total of . A Cessna plane from Belgrano I provided route reconnaissance. Sobral was fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Provinces Of Argentina
Argentina is subdivided into twenty-three federated states called provinces ( es, provincias, singular ''provincia'') and one called the autonomous city (''ciudad autónoma'') of Buenos Aires, which is the federal capital of the republic ( es, Capital Federal, links=no) as decided by the National Congress of Argentina, Argentine Congress. The provinces and the capital have their own constitutions, and exist under a federalism, federal system. History During the Argentine War of Independence, War of Independence the main cities and their surrounding countrysides became provinces though the intervention of their Cabildo (council), ''cabildos''. The Anarchy of the Year XX completed this process, shaping the original thirteen provinces. Jujuy Province, Jujuy seceded from Salta Province, Salta in 1834, and the thirteen provinces became fourteen. After seceding for a decade, Buenos Aires Province accepted the 1853 Constitution of Argentina in 1861, and its capital city was made ...

Captain (armed Forces)
The army rank of captain (from the French ) is a commissioned officer rank historically corresponding to the command of a company of soldiers. The rank is also used by some air forces and marine forces. Today, a captain is typically either the commander or second-in-command of a company or artillery battery (or United States Army cavalry troop or Commonwealth squadron). In the Chinese People's Liberation Army, a captain may also command a company, or be the second-in-command of a battalion. In some militaries, such as United States Army and Air Force and the British Army, captain is the entry-level rank for officer candidates possessing a professional degree, namely, most medical professionals (doctors, pharmacists, dentists) and lawyers. In the U.S. Army, lawyers who are not already officers at captain rank or above enter as lieutenants during training, and are promoted to the rank of captain after completion of their training if they are in the active component, or after a ...

Argentine Army
The Argentine Army ( es, Ejército Argentino, EA) is the land force branch of the Armed Forces of the Argentine Republic and the senior military service of Argentina. Under the Argentine Constitution, the president of Argentina is the commander-in-chief of the Armed Forces, exercising his or her command authority through the Minister of Defense. The Army's official foundation date is May 29, 1810 (celebrated in Argentina as the ''Army Day''), four days after the Spanish colonial administration in Buenos Aires was overthrown. The new national army was formed out of several pre-existing colonial militia units and locally manned regiments; most notably the Infantry Regiment "Patricios", which to this date is still an active unit. , the active element of the Argentine Army numbered some 70,600 military personnel. History Several armed expeditions were sent to the Upper Peru (now Bolivia), Paraguay, Uruguay and Chile to fight Spanish forces and secure Argentina's newly gain ...

Ozone
Ozone (), or trioxygen, is an inorganic molecule with the chemical formula . It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope , breaking down in the lower atmosphere to (dioxygen). Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the Earth's atmosphere. It is present in very low concentrations throughout the latter, with its highest concentration high in the ozone layer of the stratosphere, which absorbs most of the Sun's ultraviolet (UV) radiation. Ozone's odour is reminiscent of chlorine, and detectable by many people at concentrations of as little as in air. Ozone's O3 structure was determined in 1865. The molecule was later proven to have a bent structure and to be weakly diamagnetic. In standard conditions, ozone is a pale blue gas that condenses at cryogenic temperatures to a dark blue liquid and finally a violet-black soli ...

Diamond Mountains (Antarctica)
The Diamond Mountains are a mountain range along the border of Eureka and White Pine Counties, in northern Nevada, Western United States. Geography The range reaches a maximum elevation of on the summit of Diamond Peak. The range separates Newark Valley from Diamond Valley. The mountains cover an area of . The southeastern Diamond Mountains angle southwest to meet the Fish Creek Range, and the adjacent Mountain Boy Range. The flora and fauna are typical of higher elevation habitats in the Central Basin and Range ecoregion. Access The town of Eureka lies between the three ranges, with unimproved roads north across Diamond Valley to access the western flank of the range. Southeast from Eureka, U.S. 50 crosses the southern Diamond Mountains, and turns eastward at the range's south end. Nevada State Route 892 follows the eastern flank foothills for half the range's length. The route then becomes an unimproved road north past the range, then through Huntington Valley to meet ...

Meteorology
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics, and more particularly in the latter half of the 20th century the development of the computer (allowing for the automated solution of a great many modelling equations) that significant breakthroughs in weather forecasting were achieved. An important branch of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water.

Ski-Doo
Ski-Doo is a brand name of snowmobile manufactured by Bombardier Recreational Products (originally Bombardier Inc. before the spin-off). The Ski-Doo personal snowmobile brand is so iconic, especially in Canada, that it was listed in 17th place on the CBC's The Greatest Canadian Invention list in 2007. Ski-Doo also has its own range of snowmobile suits. History The first ever Ski-Doo was launched in 1959 as a new invention created by Joseph-Armand Bombardier. The original name was ''Ski-Dog'', but a typographical error in a Bombardier brochure changed the name Ski-Dog to Ski-Doo. The first Ski-Doos found customers with missionaries, Animal trapping, trappers, prospecting, prospectors, land surveyors and others who need to travel in snowy, remote areas. The largest success for the snowmobile came from sport enthusiasts, a market that opened the door to massive production of snowmobiles. This popularity led to ''skidoo'' (sometimes ''ski-doo''), with the derived verb ''skidooing' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belgrano II
Belgrano II Base ( es, Base Belgrano II) is a permanent, all year-round Argentine Antarctic base and scientific research station named after General Manuel Belgrano, one of the Libertadores and the creator of the Argentine Flag. It is located on Bertrab Nunatak on the Confín Coast, Coats Land. it is Argentina's southernmost permanent base, the world's third furthest south permanent base, and the world's southernmost base built on solid rock, which makes it particularly suited for geological research. Belgrano II is one of 13 research stations in Antarctica operated by Argentina. History In 1955, then Brigade General Hernán Pujato founded the first Belgrano Base ( Belgrano I), which remained for years as Argentina's southernmost settlement. After a continuous activity for 25 years, Belgrano I was closed due to the fast deterioration of the ice barrier it was sitting on; new, often hidden cracks and crevices endangered the on-duty personnel and material. In order to cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weddell Sea
The Weddell Sea is part of the Southern Ocean and contains the Weddell Gyre. Its land boundaries are defined by the bay formed from the coasts of Coats Land and the Antarctic Peninsula. The easternmost point is Cape Norvegia at Princess Martha Coast, Queen Maud Land. To the east of Cape Norvegia is the King Haakon VII Sea. Much of the southern part of the sea is covered by a permanent, massive ice shelf field, the Filchner-Ronne Ice Shelf. The sea is contained within the two overlapping Antarctic territorial claims of Argentine Antarctica, the British Antarctic Territory, and also resides partially within the Antarctic Chilean Territory. At its widest the sea is around across, and its area is around . Various ice shelves, including the Filchner-Ronne Ice Shelf, fringe the Weddell sea. Some of the ice shelves on the east side of the Antarctic Peninsula, which formerly covered roughly of the Weddell Sea, had completely disappeared by 2002. The Weddell Sea has been deemed by ...

Antarctic Plateau
The Antarctic Plateau, Polar Plateau or King Haakon VII Plateau is a large area of East Antarctica which extends over a diameter of about , and includes the region of the geographic South Pole and the Amundsen–Scott South Pole Station. This huge continental plateau is at an average elevation of about . Exploration This plateau was first sighted in 1903 during the ''Discovery'' Expedition to the Antarctic, which was led by Robert Falcon Scott. Ernest Shackleton became the first to cross parts of this plateau in 1909 during his ''Nimrod'' Expedition, which turned back in bad weather when it had reached a point just from the South Pole. Shackleton named this plateau the King Edward VII Plateau in honour of the king of the United Kingdom. In December 1911, while returning from the first journey to the South Pole, the Norwegian explorer Roald Amundsen decided to name this plateau the King Haakon VII Plateau in honour of the newly elected king of Norway.
