Dome A
Dome A or Dome Argus is the loftiest ice dome on the Antarctic Plateau, located inland. It is thought to be the coldest naturally occurring place on Earth, with temperatures believed to reach . It is the highest ice feature in Antarctica, consisting of an ice dome or eminence above sea level. It is located near the center of East Antarctica, approximately midway between the enormous head of Lambert Glacier and the geographic South Pole, within the Australian claim. Description Dome Argus is located on the massive East Antarctic Ice Sheet and is the highest ice feature of Antarctica. Dome A is a lofty ice prominence, the highest rooftop of the Antarctic Plateau, and the elevation visually is not noticeable. Below this enormous dome, underneath at least of ice sheet, lies the Gamburtsev Mountain Range, about the size of the European Alps. The name "Dome Argus" was given by the Scott Polar Research Institute from Greek mythology. Argus built the ship ''Argo'', in which Jas ...

Ultra Prominent Peak
An ultra-prominent peak, or Ultra for short, is a mountain summit with a topographic prominence of or more; it is also called a P1500. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,524 such peaks on Earth. Some well-known peaks, such as the Matterhorn and Eiger, are not Ultras because they are connected to higher mountains by high cols and therefore do not achieve enough topographic prominence. The term "Ultra" originated with earth scientist Steve Fry, from his studies of the prominence of peaks in Washington in the 1980s. His original term was "ultra major mountain", referring to peaks with at least of prominence. Distribution Currently, 1,518 Ultras have been identified above sea level: 639 in Asia, 356 in North America, 209 in South America, 120 in Europe (including 12 in the Caucasus), 84 in Africa, 69 in Oceania, and 41 in Antarctica. ...

Golden Fleece
In Greek mythology, the Golden Fleece ( el, Χρυσόμαλλον δέρας, ''Chrysómallon déras'') is the fleece of the golden-woolled,, ''Khrusómallos''. winged ram, Chrysomallos, that rescued Phrixus and brought him to Colchis, where Phrixus then sacrificed it to Zeus. Phrixus gave the fleece to King Aeëtes who kept it in a sacred grove, whence Jason and the Argonauts stole it with the help of Medea, Aeëtes' daughter. The fleece is a symbol of authority and kingship. In the historical account, the hero Jason and his crew of Argonauts set out on a quest for the fleece by order of King Pelias in order to place Jason rightfully on the throne of Iolcus in Thessaly. Through the help of Medea, they acquire the Golden Fleece. The story is of great antiquity and was current in the time of Homer (eighth century BC). It survives in various forms, among which the details vary. Nowadays, the heraldic variations of the Golden Fleece are featured frequently in Georgia, especial ...

Antarctic Kunlun Station
Kunlun Station () is the southernmost of four Chinese research stations in Antarctica. When it is occupied during the summer, it is the second-southernmost research base in Antarctica, behind only the American Amundsen–Scott South Pole Station at the geographical South Pole. When Kunlun is not in operation, the year-round Russian Vostok Station is the second-southernmost base in Antarctica. It is located at 4087 m above sea level on the East Antarctic Ice Sheet, making it the highest base in Antarctica. It is only 7.3 km southwest of Dome A, the loftiest point on the Antarctic Plateau. The station was officially opened on January 27, 2009. Fully constructed the station is planned to cover an area of 558 m². The main building, covering 236 m², is planned erected in April 2009.

Ridge A
Ridge A is a site in Antarctica that was identified in 2009 as the best suited location on the surface of Earth for astronomical research. The site, approximately from the South Pole and southeast of Dome A, is situated in a portion of Antarctica claimed by Australia in the Australian Antarctic Territory. The site is on the Antarctic Plateau at an altitude of , and has an average winter temperature of . It is possible that this site may have even lower temperatures than Dome A, with temperatures that might as low or even colder than the ''legendary'' mark of -100°C (-148°F). Ridge A was identified by a team of Australian and American scientists searching for the best observatory spot in the world. The team leader described the site as "so calm there's almost no wind or weather there at all."Kenber, Billy"Scientists identify coldest place on earth" ''The Telegraph'', September 1, 2009.

Diesel Fuel
Diesel fuel , also called diesel oil, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel. Therefore, diesel fuel needs good compression ignition characteristics. The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil, but alternatives that are not derived from petroleum, such as biodiesel, biomass to liquid (BTL) or gas to liquid (GTL) diesel are increasingly being developed and adopted. To distinguish these types, petroleum-derived diesel is sometimes called petrodiesel in some academic circles. In many countries, diesel fuel is standardised. For example, in the European Union, the standard for diesel fuel is EN 590. Diesel fuel has many colloquial names; most commonly, it is simply referred to as ''diesel''. In the United Kingdom, diesel fuel for on-road use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Weather Station
A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate. The measurements taken include temperature, atmospheric pressure, humidity, wind speed, wind direction, and precipitation amounts. Wind measurements are taken with as few other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once daily, while automated measurements are taken at least once an hour. Weather conditions out at sea are taken by ships and buoys, which measure slightly different meteorological quantities such as sea surface temperature (SST), wave height, and wave period. Drifting weather buoys outnumber their moored versions by a significant amount. Weather instruments Typical weather stations have the following instruments: * Thermometer ...

Ice Divide
An ice divide is the boundary on an ice sheet, ice cap or glacier separating opposing flow directions of ice, analogous to a water divide. Ice divides are important for geochronological investigations that use ice cores, since such coring is typically made at highest point of an ice sheet dome to avoid disturbances arising from horizontal ice movement. Ice divides are used for looking at how the atmosphere varied over time. Coring at dome peaks increases precision of reconstructions as it is the place where horizontal motion is at its least. The Raymond Effect operates at ice divides, creating anticlines in the radar-detected isochrones, allowing greater capture of older ice when coring. Analysis of ice cores relies on the downward motion of ice, trapping changes of atmospheric gases through time into its layers. Scientist locate ice divides and take ice cores from them, which are typically long cylindrical poles of ice, and analyse them to find chemical elements that the snow an ...
