Svalbard
Svalbard ( , ), also known as Spitsbergen, or Spitzbergen, is a Norwegian archipelago in the Arctic Ocean. North of mainland Europe, it is about midway between the northern coast of Norway and the North Pole. The islands of the group range from 74° to 81° north latitude, and from 10° to 35° east longitude. The largest island is Spitsbergen, followed by Nordaustlandet and . The largest settlement is Longyearbyen. The islands were first used as a base by the whalers who sailed far north in the 17th and 18th centuries, after which they were abandoned. Coal mining started at the beginning of the 20th century, and several permanent communities were established. The Svalbard Treaty of 1920 recognizes Norwegian sovereignty, and the 1925 Svalbard Act made Svalbard a full part of the Kingdom of Norway. They also established Svalbard as a free economic zone and a demilitarized zone. The Norwegian Store Norske and the Russian remain the only mining companies in place. Res ...

Latitude
In geography, latitude is a coordinate that specifies the north– south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from –90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or ''parallels'', run east–west as circles parallel to the equator. Latitude and ''longitude'' are used together as a coordinate pair to specify a location on the surface of the Earth. On its own, the term "latitude" normally refers to the ''geodetic latitude'' as defined below. Briefly, the geodetic latitude of a point is the angle formed between the vector perpendicular (or ''normal'') to the ellipsoidal surface from the point, and the plane of the equator. Background Two levels of abstraction are employed in the definitions of latitude and longitude. In the first step the physical surface is modeled by the geoid, a surface which approximates the mean sea level over the ocean ...

Earth Observing System
The Earth Observing System (EOS) is a program of NASA comprising a series of artificial satellite missions and scientific instruments in Earth orbit designed for long-term global observations of the land surface, biosphere, atmosphere, and oceans. Since the early 1970s, NASA has been developing its Earth Observing System, launching a series of LANDSAT satellites in the decade. Some of the first included Passive-Microwave imaging in 1972 through the Nimbus 5 Satellite. Following the launch of various satellite missions, the conception of the program began in the late 80s and expanded rapidly through the 90s. Since the inception of the program, it has continued to develop to what we can collect in data today, including; land, sea, radiation and atmosphere. Collected in a system known as EOSDIS, NASA uses this data in order to study the progression and changes in the biosphere of Earth. The main focus of this data collection surrounds climatic science. The program is the centrepiece o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norse Mythology
Norse, Nordic, or Scandinavian mythology is the body of myths belonging to the North Germanic peoples, stemming from Old Norse religion and continuing after the Christianization of Scandinavia, and into the Nordic folklore of the modern period. The northernmost extension of Germanic mythology and stemming from Proto-Germanic folklore, Norse mythology consists of tales of various deities, beings, and heroes derived from numerous sources from both before and after the pagan period, including medieval manuscripts, archaeological representations, and folk tradition. The source texts mention numerous gods such as the thunder-god Thor, the raven-flanked god Odin, the goddess Freyja, and numerous other deities. Most of the surviving mythology centers on the plights of the gods and their interaction with several other beings, such as humanity and the jötnar, beings who may be friends, lovers, foes, or family members of the gods. The cosmos in Norse mythology consists of Nine Worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Troll
A troll is a being in Nordic folklore, including Norse mythology. In Old Norse sources, beings described as trolls dwell in isolated areas of rocks, mountains, or caves, live together in small family units, and are rarely helpful to human beings. In later Scandinavian folklore, trolls became beings in their own right, where they live far from human habitation, are not Christianized, and are considered dangerous to human beings. Depending on the source, their appearance varies greatly; trolls may be ugly and slow-witted, or look and behave exactly like human beings, with no particularly grotesque characteristic about them. Trolls are sometimes associated with particular landmarks in Scandinavian folklore, which at times may be explained as formed from a troll exposed to sunlight. Trolls are depicted in a variety of media in modern popular culture. Etymology The Old Norse nouns ''troll'' and ''trǫll'' (variously meaning "fiend, demon, werewolf, jötunn") and Middle High Germa ...

Longyearbyen
Longyearbyen (, locally lɔ̀ŋjɑrˌbyːən "The Longyear Town") is the world's northernmost settlement with a population greater than 1,000 and the largest inhabited area of Svalbard, Norway. It stretches along the foot of the left bank of the Longyear Valley and on the shore of Adventfjorden, the short estuary leading into Isfjorden on the west coast of Spitsbergen, the island's broadest inlet. As of 2002 Longyearbyen Community Council became an official Norwegian municipality. It is the seat of the Governor of Svalbard. The town's mayor is Arild Olsen. Known as Longyear City until 1926, the town was established by and named after American John Munro Longyear, whose Arctic Coal Company started coal-mining there in 1906. Store Norske Spitsbergen Kulkompani (SNSK) took over the mining operations in 1916, and still conducts mining. The German ''Kriegsmarine'' almost completely destroyed the town on 8 September 1943, but rebuilding took place after the Second World Wa ...
