The system is installed in the central building and ensures that all equipment has plentiful, good quality power all year round. In terms of power supply, AS72 is powered by a state-of-the-art hybrid power system composed of two power generators, a windmill and an “intelligent power management module”. Snow avalanches are frequent, especially on downwind slopes. an Inuit word for a mound of earth-covered ice found in the Arctic, subarctic and Antarctica that can reach up to 70 m in height and up to 2 km in diameter), ice wedges and rock glaciers are widespread. At the coast the perma-frost thickness is 10 to 40 m, but increases to more than 450 m in the highlands. Spitsbergen falls within the zone of continuous permafrost. In these more humid coastal regions, glacier velocities frequently are more than 10 to 30 m per year, causing large crevasses to form. Large valley glaciers and ice caps are frequent along both the west and east coasts of Spitsbergen. There may be very windy periods during winter, and fog is common during the summertime in coastal areas. Meteorologically, this border zone is very active at times with cyclones generating unstable, often stormy weather. December to January may see heavy snowfalls. It is usually dry between April and May while it is comparatively humid between February and March and August and September. Precipitation, predominantly in the form of snow, measured at sea level is low, only about 200 mm in central Spitsbergen, though somewhat higher along the coast. The climate of Svalbard is arctic, with mean annual air temperatures of about –6 oC at sea level and as low as –15 oC in the high mountains. On the other hand, the red Devonian sandstone of northern Spitsbergen was deposited when Svalbard was close to the Equator, some 350 to 400 million years ago. unsorted glacial sediment) deposits on Svalbard were probably from the time when Spitsbergen was situated close to the South Pole, some 600 million years ago. ![]() A great deal can be learned there about the development of tectonic features and sedimentary environments through time, as well as about the drift of continents across the Earth’s surface.įor example, the oldest till (i.e. Geologically, Svalbard has a very long, rich, diverse history that makes it attractive to geologists. The highest peak is Newtontoppen (1,717 m) in the northeast of the island. ![]() Spitsbergen’s landscape is characterized by rugged, steep-flanked mountains, with large, glacially eroded fjord systems. The highest elevation is 1,717m and most of the archipelago is mountainous and dotted with large and small glaciers. It consists of four main islands and some 150 smaller ones totalling 62,800 km2, 60% of which is a glacier. The Svalbard Archipelago, which means “Cold Coast”, is located midway between Norway and the North Pole.
