Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Spitsbergen
Spitsbergen (; formerly known as West Spitsbergen; Norwegian: ''Vest Spitsbergen'' or ''Vestspitsbergen'' , also sometimes spelled Spitzbergen) is the largest and the only permanently populated island of the Svalbard archipelago in northern Norway. Constituting the westernmost bulk of the archipelago, it borders the Arctic Ocean, the Norwegian Sea, and the Greenland Sea. Spitsbergen covers an area of , making it the largest island in Norway and the 36th-largest in the world. The administrative centre is Longyearbyen. Other settlements, in addition to research outposts, are the Russian mining community of Barentsburg, the research community of Ny-Ålesund, and the mining outpost of Sveagruva. Spitsbergen was covered in of ice in 1999, which was approximately 58.5% of the island's total area. The island was first used as a whaling base in the 17th and 18th centuries, after which it was abandoned. Coal mining started at the end of the 19th century, and several permanent commun ...

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 ...

Wijdefjorden
Wijdefjord is the longest fjord in Norway's Svalbard archipelago. Wijdefjord is located in the northern portion of the island of Spitsbergen, which lies in the Arctic Ocean about midway between Norway and the North Pole, and is the largest island in the archipelago. The fjord is long. Opening on Spitsbergen's north coast, it runs roughly southwards into the interior, separating Andrée Land in the west from Margaretas Land in the east. The southern half of the fjord is part of Indre Wijdefjorden National Park Indre Wijdefjorden National Park ( no, Indre Wijdefjorden nasjonalpark) is located in a steep fjord landscape in northern Spitsbergen in Svalbard, Norway. It covers the inner part of Wijdefjorden—the longest fjord on Svalbard. The national ....

Kongsfjorden
Kongsfjorden as seen from Blomstrandhalvøya Kongsfjorden (Kongs Fjord or Kings Bay) is an inlet on the west coast of Spitsbergen, an island which is part of the Svalbard archipelago in the Arctic Ocean. The inlet is long and ranges in width from 6 to 14 km (4 to 9 miles). Two glaciers, Kronebreen and Kongsvegen, head the fjord. The coal-mining town of Ny-Ålesund is located on its southern shore and is one of the few permanent settlements on Spitsbergen. It is also a popular shore break for cruise ships, although local scientists who monitor levels as part of their climate change research have voiced concerns that the excessive pollution generated by cruise ships is interfering with their measurements. Kongsfjorden was originally named ''Deer Sound'' by Jonas Poole (1610), and was known as such by the English whalers until at least 1658. Giles and Rep (c. 1710) were the first to name it ''Koninks Bay''. William Scoresby William Scoresby (5 October 178921 March 1 ...

Ice Cap
In glaciology, an ice cap is a mass of ice that covers less than of land area (usually covering a highland area). Larger ice masses covering more than are termed ice sheets. Description Ice caps are not constrained by topographical features (i.e., they will lie over the top of mountains). By contrast, ice masses of similar size that ''are'' constrained by topographical features are known as ice fields. The ''dome'' of an ice cap is usually centred on the highest point of a massif. Ice flows away from this high point (the ice divide) towards the ice cap's periphery. Ice caps have significant effects on the geomorphology of the area that they occupy. Plastic moulding, gouging and other glacial erosional features become present upon the glacier's retreat. Many lakes, such as the Great Lakes in North America, as well as numerous valleys have been formed by glacial action over hundreds of thousands of years. On Earth, there are about of total ice mass.

Olaf Holtedahl
Prof Olaf Holtedahl ForMemRS FRSE (24 June 1885 – 26 August 1975) was a Norwegian geologist (Dr.philos., 1913). He became a senior lecturer at the University of Oslo in 1914, and was Professor of Geology there from 1920 to 1956. Career Olaf Holtedahl was born in Kristiania (modern-day Oslo), Norway, the son of Arne H. Holtedahl, superintendent of pauper administration, and his wife, Mathilde Madsen. Around 1903 he did his obligatory military service at Gardermoen, just north of Oslo, and here met Captain Gunnar Isachsen who greatly influenced him, and first inspired his interest in polar regions. In 1909, Isachsen invited Holtedahl to join him in explorations of Spitsbergen as official geologist of the group. He studied Geology at the University of Oslo, graduating in 1909 and receiving a doctorate in 1913. Staying in the university as staff he received his professorship in 1920. Holtedahl was among the last of a generation of geologists that mastered the subject in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norwegian Polar Institute
The Norwegian Polar Institute (NPI; no, Norsk Polarinstitutt) is Norway's central governmental institution for scientific research, mapping and environmental monitoring in the Arctic and the Antarctic. The NPI is a directorate under Norway's Ministry of Climate and Environment. The institute advises Norwegian authorities on matters concerning polar environmental management and is the official environmental management body for Norwegian activities in Antarctica. Activities The institute's activities are focused on environmental research and management in the polar regions. The NPI's researchers investigate biodiversity, climate and environmental toxins in the Arctic and Antarctic, and in this context the institute equips and organizes large-scale expeditions to both polar regions. The institute contributes to national and international climate work, and is an active contact point for the international scientific community.

Store Norske Leksikon
The ''Great Norwegian Encyclopedia'' ( no, Store Norske Leksikon, abbreviated ''SNL''), is a Norwegian-language online encyclopedia. The online encyclopedia is among the most-read Norwegian published sites, with more than two million unique visitors per month. Paper editions 1978–2007 The ''SNL'' was created in 1978, when the two publishing houses Aschehoug and Gyldendal merged their encyclopedias and created the company Kunnskapsforlaget. Up until 1978 the two publishing houses of Aschehoug and Gyldendal, Norway's two largest, had published ' and ', respectively. The respective first editions were published in 1907–1913 (Aschehoug) and 1933–1934 (Gyldendal). The slump in sales for paper-based encyclopedias around the turn of the 21st century hit Kunnskapsforlaget hard, but a fourth edition of the paper encyclopedia was secured by a grant of ten million Norwegian kroner from the foundation Fritt Ord in 2003. The fourth edition consisted of 16 volumes, a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
