Børglum River
The Børglum River ( da, Børglum Elv) is a river in Peary Land, Greenland. It is the largest river in Greenland. Administratively it is part of the Northeast Greenland National Park. The Børglum River Formation is named after the river. Fossils dating back to the Ordovician have been found in it. The Børglum River Formation was deposited in the paleoequatorial marginal seas of Laurentia during the Katian. Course The Børglum River is formed on the southern slopes of the Nordkrone. After leaving the mountains it heads roughly southwards across the desolate territories of the western limit of Melville Land, an unglaciated area. Finally it bends southwestwards and joins the left side of the Brønlund Fjord from its mouth in the Independence Fjord. The river receives many tributaries along its course. The river was first mapped by Danish Arctic explorer Lauge Koch during his Cartographic Air Expedition Cartography (; from grc, χάρτης , "papyrus, sheet of paper ...

Nordkrone
Nordkrone ( da, Nordkronen, meaning "Northern Crown") is a mountainous area in Peary Land, Northern Greenland. Administratively it is part of the Northeast Greenland National Park. Fossils dating back to the Silurian have been found in the area of the range. They belong to the Nordkronen Formation of the Peary Land Group. History The mountain was mapped by Danish Arctic explorer Lauge Koch during his Cartographic Air Expedition of 1938. He named it after the "North Crown", which symbolically crowns the world's northernmost country. The most conspicuous peak in the area had been previously named by Robert Peary as Mount Wistar ''(Wistars Fjeld)''. In 1950 Eigil Knuth, the leader of the Danish Peary Land Expedition, asserted that the mountain was part of Nordkrone, and described it as "the strangest and proudest peak" of Peary Land: Geography Nordkrone is located in central Peary Land, to the south of Frederick E. Hyde Fjord, describing an arc to the east and northwest of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Katian
The Katian is the second stage of the Upper Ordovician. It is preceded by the Sandbian and succeeded by the Hirnantian Stage. The Katian began million years ago and lasted for about 7.8 million years until the beginning of the Hirnantian million years ago. During the Katian the climate cooled which started the Late Ordovician glaciation. Naming The name Katian is derived from Katy Lake (Atoka County, Oklahoma, United States). GSSP The GSSP of the Katian Stage is the Black Knob Ridge Section in southeastern Oklahoma (United States). It is an outcrop of the Womble Shale and the Bigfork Chert, the latter containing the lower boundary of the Katian. The lower boundary is defined as the first appearance datum of the graptolite Graptolites are a group of colonial animals, members of the subclass Graptolithina within the class Pterobranchia. These filter-feeding organisms are known chiefly from fossils found from the Middle Cambrian ( Miaolingian, Wuliuan) through t ... ...

Børglum Abbey
Børglum Abbey was an important Premonstratensian abbey of medieval Denmark, located in Børglum parish, in the commune of Hjørring, approximately five kilometers east of Løkken in north central Jutland (Region Nordjylland) from the 12th century until reformation. History Origin Børglum Abbey was originally a royal farm ( da, gård) which dated back as far as 1000, if not earlier. In 1086 King Canute IV fled from his residence at Børglum when the peasants revolted against him. The royal residence was burned to the ground but rebuilt sometime later. At some point between 1134 and 1139, the royal estate at Børglum was granted to the church to become the new seat of the bishopric of northern Jutland, also known as the bishopric of Vendsyssel, previously established at Vestervig. Bishop Self (or Sylvester) of Vestervig became the first bishop of Børglum (Vendsyssel) in 1139, and Børglum remained the seat of the diocese until the Reformation. It is unclear exactly who fir ...

Cartographic Air Expedition
Cartography (; from grc, χάρτης , "papyrus, sheet of paper, map"; and , "write") is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively. The fundamental objectives of traditional cartography are to: * Set the map's agenda and select traits of the object to be mapped. This is the concern of map editing. Traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries. * Represent the terrain of the mapped object on flat media. This is the concern of map projections. * Eliminate characteristics of the mapped object that are not relevant to the map's purpose. This is the concern of generalization. * Reduce the complexity of the characteristics that will be mapped. This is also the concern of generalization. * Orchestrate the elements of the ...

Lauge Koch
Lauge Koch (5 July 1892 – 5 June 1964) was a Danish geologist and Arctic explorer. Biography Lauge Koch was born in 1892 to Karl and Elisabeth Koch. His development as a scientist was greatly influenced by his father's second cousin Johan Peter Koch - a polar explorer, a member of several Greenland expeditions, including Ludvig Mylius-Erichsen's and Alfred Wegener's (in the latter's expedition (1912-1913) to cross Greenland, he led a sledging party). He received his higher education at the University of Copenhagen, where he began his studies in 1911, in 1920 he received a master's degree, and in 1929 a doctor's degree, having defended a dissertation on the topic " Stratigraphy of Greenland". General He was the renowned leader of 24 Danish government expeditions to Greenland, and the central character in the ''Lauge Koch Controversy'', an international and intra-national conflict. Beginning in December 1935 a bitter conflict arose between Koch and eleven of the most promin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Explorer
Arctic exploration is the physical exploration of the Arctic region of the Earth. It refers to the historical period during which mankind has explored the region north of the Arctic Circle. Historical records suggest that humankind have explored the northern extremes since 325 BC, when the ancient Greek sailor Pytheas reached a frozen sea while attempting to find a source of the metal tin. Dangerous oceans and poor weather conditions often fetter explorers attempting to reach polar regions and journeying through these perils by sight, boat, and foot has proven difficult. Ancient history Indo-European Hypothesis A controversial hypothesis, often regarded as pseudohistory, sets the home of the mythical people Hyperboreans in the Arctic. The scientist and author John G. Bennett talked about it in his research paper "The Hyperborean Origin of the Indo-European Culture" (1963). The theory was originally put forth by William F. Warren, the first President of Boston University, in h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unglaciated
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 over many years, often centuries. It acquires distinguishing features, such as crevasses and 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. Between latitudes 35°N and 35°S, glaciers occur only in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melville Land
Melville Land is an area in Peary Land, North Greenland. Administratively it is part of the Northeast Greenland National Park. Google Maps History Robert Peary named the territory, together with Heilprin Land, in 1892 during his North Greenland Expedition sponsored by the Academy of Natural Sciences in Philadelphia. He named it after Chief Engineer George W. Melville (1841–1912), chief of the Bureau of Steam Engineering of the United States Navy. Peary sighted the coast of Melville Land shore from afar to the northeast. He drew a rough map based on the panorama that he saw from Navy Cliff, at the head of Independence Fjord, but did not explore the area.Peary, Robert E.

Laurentia
Laurentia or the North American Craton is a large continental craton that forms the ancient geological core of North America. Many times in its past, Laurentia has been a separate continent, as it is now in the form of North America, although originally it also included the cratonic areas of Greenland and also the northwestern part of Scotland, known as the Hebridean Terrane. During other times in its past, Laurentia has been part of larger continents and supercontinents and itself consists of many smaller terranes assembled on a network of Early Proterozoic orogenic belts. Small microcontinents and oceanic islands collided with and sutured onto the ever-growing Laurentia, and together formed the stable Precambrian craton seen today. The craton is named after the Laurentian Shield, through the Laurentian Mountains, which received their name from the Saint Lawrence River, named after Lawrence of Rome. Interior platform In eastern and central Canada, much of the stable cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ordovician
The Ordovician ( ) is a geologic period and system, the second of six periods of the Paleozoic Era. The Ordovician spans 41.6 million years from the end of the Cambrian Period million years ago (Mya) to the start of the Silurian Period Mya. The Ordovician, named after the Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879 to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same rock beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed strata were different from those of either the Cambrian or the Silurian systems, and placed them in a system of their own. The Ordovician received international approval in 1960 (forty years after Lapworth's death), when it was adopted as an official period of the Paleozoic Era by the International Geological Congress. Life continued to flourish during the Ordovician as it did in the earlier Cambrian P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
