Pic De Gerlache
Pic de Gerlache is a mountain in King Frederick VIII Land, NE Greenland. Administratively it is part of the Northeast Greenland National Park. History This nunatak was named in 1905 by the Prince Philippe, Duke of Orléans (1869–1926), Duke of Orléans during his Duke of Orléans Arctic Expedition, Arctic Expedition on ship RV Belgica (1884), Belgica, when he explored parts of the northeastern coast of Greenland. He named it after Belgian explorer Adrien de Gerlache (1866–1934). Although this peak was an important landmark for the first explorers of the area, the 1906–08 Danmark Expedition was unable to identify the original peak. Since the expedition members considered that the name should be preserved, it was placed on a conspicuous mountain rising on the north side of Gammel Hellerup Glacier.''Catalogue of place names in northern East Greenland'', Geological Survey of Denmark and Greenland A few years later, Ejnar Mikkelsen described this mountain as a Pyramid (geome ...

GoogleEarth
Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering addresses and coordinates, or by using a keyboard or mouse. The program can also be downloaded on a smartphone or tablet, using a touch screen or stylus to navigate. Users may use the program to add their own data using Keyhole Markup Language and upload them through various sources, such as forums or blogs. Google Earth is able to show various kinds of images overlaid on the surface of the earth and is also a Web Map Service client. In 2019, Google has revealed that Google Earth now covers more than 97 percent of the world, and has captured 10 million miles of Street View imagery. In addition to Earth navigation, Google Earth provides a series of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Operational Navigation Chart B-9, 1st Edition
An operational definition specifies concrete, replicable procedures designed to represent a construct. In the words of American psychologist S.S. Stevens (1935), "An operation is the performance which we execute in order to make known a concept." For example, an operational definition of "fear" (the construct) often includes measurable physiologic responses that occur in response to a perceived threat. Thus, "fear" might be operationally defined as specified changes in heart rate, galvanic skin response, pupil dilation, and blood pressure. Overview An operational definition is designed to model or represent a concept or theoretical definition, also known as a construct. Scientists should describe the operations (procedures, actions, or processes) that define the concept with enough specificity such that other investigators can replicate their research. Operational definitions are also used to define system states in terms of a specific, publicly accessible process of preparation ...

Jokel Bay
Jokel Bay ( da, Jøkelbugten) is a large bay in North Eastern Greenland. The area of the bay is uninhabited. Administratively Jokel Bay and its surroundings belong to the Northeast Greenland National Park. The bay was named after an old Norse word for glacier — is, Jökull— by the ill-fated Denmark expedition. Jokel Bay is clogged by fast ice the year round. Geography Jokel Bay stretches for about 140 kilometers from north to south in the King Frederick VIII Land shore. Lambert Land and Schnauder Island lie at the northern end by the Zachariae Isstrom glacier, while Duke of Orleans Land and Gamma Island are at the southern end. All along the shore of the bay the Greenland ice sheet reaches down to the sea between skerries and the coast is broken down into two alignments of small islands. The Pic de Gerlache, an important landmark for the first explorers of the area, rises from a nunatak A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that prot ...

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lambert Land
Lambert Land is a land area —possibly a peninsula or an island— in King Frederick VIII Land, northeastern Greenland. Administratively it belongs to the NE Greenland National Park area. Geography Lambert Land is bounded in the north by the Nioghalvfjerd Fjord, in the east by the Greenland Sea and in the south by the Zachariae Isstrom, beyond which rises Duke of Orleans Land. Jomfru Tidsfordriv Fjord is a small fjord in the eastern coast. Cape Drygalsky is its eastern headland. To the northeast lie the Gamle Jim Islands and to the southeast Jokel Bay. Lambert Land is largely unglaciated. History Lambert Land was named by the 1906-1908 Denmark expedition after a name found in a 1718 map of an obscure Dutch whaler who had sighted that land in 1670.''Catalogue of place names in northern East Greenland'', Geological Survey of Denmark (GEUS) Jørgen Brønlund, the last survivor of the ill-fated leading team of the Denmark expedition reached Lambert Land in the moonlight an ...

Alabama Expedition
''Two Against the Ice'' is a non-fiction book authored by Danish explorer Ejnar Mikkelsen. The book details the author's exploration into Greenland, a journey made with his compatriot Iver P. Iversen in 1910. The book was originally published in Danish (1955) and later translated into English by Maurice Michael (first published in 1957). Summary Mikkelsen recounts his round-trip 2,500 mile sledge journey from Shannon Island to Danmark Fjord. A task which soon became a battle for survival as rations ran low, and the sled dogs began to starve to death, or were intentionally shot in order to provide food for the other dogs. The two adventurers became so hungry that they began to hallucinate. In a notable moment that typifies the hunger pains that the men were suffering, Iversen no longer wished to carry his rifle out of a fear he may be compelled to shoot Mikkelsen. The purpose of their travels was to locate the maps and journals of previous explorer Mylius Erichsen of the ill- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyramid (geometry)
In geometry, a pyramid () is a polyhedron formed by connecting a polygonal base and a point, called the apex. Each base edge and apex form a triangle, called a ''lateral face''. It is a conic solid with polygonal base. A pyramid with an base has vertices, faces, and edges. All pyramids are self-dual. A right pyramid has its apex directly above the centroid of its base. Nonright pyramids are called oblique pyramids. A regular pyramid has a regular polygon base and is usually implied to be a ''right pyramid''. When unspecified, a pyramid is usually assumed to be a ''regular'' square pyramid, like the physical pyramid structures. A triangle-based pyramid is more often called a tetrahedron. Among oblique pyramids, like acute and obtuse triangles, a pyramid can be called ''acute'' if its apex is above the interior of the base and ''obtuse'' if its apex is above the exterior of the base. A right-angled pyramid has its apex above an edge or vertex of the base. In a tetrahedro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ejnar Mikkelsen
Ejnar Mikkelsen (December 23, 1880 – May 1, 1971) was a Danish polar explorer and author. He is most known for his expeditions to Greenland. Biography Mikkelsen was born in Vester Brønderslev, Jutland. He served in the Georg Carl Amdrup expedition to Christian IX Land, East Greenland (1900), and in the Baldwin-Ziegler North Pole Expedition to Franz Joseph Land (1900–02). With Ernest de Koven Leffingwell he organized the Anglo-American polar expedition which wintered off Flaxman Island, Alaska, in 1906–07. They lost their ship, but in a sledge journey over the ice they located the continental shelf of the Arctic Ocean, 65 miles (105 km) offshore, where in 2 miles (3 km) the sea increased from 50 meters (164 ft) to more than 690 meters (2264 ft) in depth.Mills, William James (2003"Mikkelsen, Ejnar (1880–1971)"''Exploring polar frontiers: a historical encyclopedia, Volume 1'' pp 426 ff, ABC-CLIO , Organizing an expedition to map out the northeast ...

Danmark Expedition
The Denmark expedition ( da, Danmark-ekspeditionen), also known as the Denmark Expedition to Greenland's Northeast Coast, and as the Danmark Expedition after the ship, was an expedition to the northeast of Greenland in 1906–1908. Despite being overshadowed by the death in tragic circumstances of the main exploration team, including three of the expedition's leading members: Ludvig Mylius-Erichsen (1872–1907), Niels Peter Høeg Hagen (1877–1907) and Jørgen Brønlund (1877–1907), the Denmark expedition was not a failure. It achieved its main cartographic objectives and succeeded in exploring the vast region, drawing accurate charts of formerly unexplored coastlines and fjords, naming numerous geographic features, and gathering a wealth of scientific data. Purposes The two-year expedition was conceived and led by Ludvig Mylius-Erichsen, who had previously led the 'Literary Expedition' to Northwest Greenland together with Knud Rasmussen in 1902–1904. The main target of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
