Greenland Sea
The Greenland Sea is a body of water that borders Greenland to the west, the Svalbard archipelago to the east, Fram Strait and the Arctic Ocean to the north, and the Norwegian Sea and Iceland to the south. The Greenland Sea is often defined as part of the Arctic Ocean, sometimes as part of the Atlantic Ocean. However, definitions of the Arctic Ocean and its seas tend to be imprecise or arbitrary. In general usage the term "Arctic Ocean" would exclude the Greenland Sea. In oceanographic studies the Greenland Sea is considered part of the Nordic Seas, along with the Norwegian Sea. The Nordic Seas are the main connection between the Arctic and Atlantic oceans and, as such, could be of great significance in a possible shutdown of thermohaline circulation. In oceanography the Arctic Ocean and Nordic Seas are often referred to collectively as the "Arctic Mediterranean Sea", a marginal sea of the Atlantic. The sea has Arctic climate with regular northern winds and temperatures rarely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers) for more than a millennium, beginning in 986.The Fate of Greenland's Vikings , by Dale Mackenzie Brown, ''Archaeological Institute of America'', ...

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 ...

Danske Islands
Danske Islands, da, Danske Øer; meaning 'Danish Islands', is an island group of the Greenland Sea, NE Greenland. The islands are uninhabited. Administratively they belong to the Northeast Greenland National Park. Name conflict This island group was named by John Haller during the 1956–1958 Expedition to East Greenland led by Lauge Koch, to pay tribute to the work of the 1906–08 Denmark expedition. Previously the Duke of Orléans in 1905 had given the name "Îles Françaises" to an island group further north, approximating to the position of the present Franske Islands. A few years later the 1906–08 Denmark expedition had transferred the name "Franske Islands" to that position, corresponding to the northernmost islands the Duke of Orléans Arctic Expedition could have seen. A number of maps, such as the World Aeronautical Charts of 1952, among others, retain the outdated names for this island group located further south —"Franske Islands" or ''Îles Françaises''. Ge ...

Mørkefjord Expedition
Mørkefjord, meaning in Danish "The dark fjord," is a fjord in King Frederick VIII Land, northeastern Greenland. History Mørkefjord was named by the 1906-1908 Denmark expedition, which established a second weather station at Mørkefjord, in order to compare meteorological observations data with those taken at Danmarkshavn . It had also been known as ''Vigfusdalfjord''. The 1938–1939 Mørkefjord expedition was named after it. They built their base hut and repaired their ship "Gamma" at a place by the fjord's shores. There are remains of Inuit sites at the mouth of the fjord.Spencer Apollonio, ''Lands That Hold One Spellbound: A Story of East Greenland,'' 2008, p. 258 Geography This fjord is located east of Danmarkshavn in Daniel Bruun Land. There are two parallel fjords close to it, Hellefjord to the south, and Sælsøen, a lake with a fjord structure, to the north. It runs from east to west for about 30 km. There is a small branch on its southern shore. Kalvenø island is l ... [...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 ...

Mylonite
Mylonite is a fine-grained, compact metamorphic rock produced by dynamic recrystallization of the constituent minerals resulting in a reduction of the grain size of the rock. Mylonites can have many different mineralogical compositions; it is a classification based on the textural appearance of the rock. Formation Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones. There are many different views on the formation of mylonites, but it is generally agreed that crystal-plastic deformation must have occurred, and that fracturing and cataclastic flow are secondary processes in the formation of mylonites. Mechanical abrasion of grains by milling does not occur, although this was originally thought to be the process that formed mylonites, which were named from the Greek μύλος ''mylos'', meaning mill. Mylonites form at depths of no less than 4 km. There are many different mechanisms that accommodate crystal-plastic def ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cataclasite
Cataclasite is a cohesive granular fault rock. Comminution, also known as cataclasis, is an important process in forming cataclasites. They fall into the category of cataclastic rocks which are formed through faulting or fracturing in the upper crust. Cataclasites are distinguished from fault gouge, which is incohesive, and fault breccia, which contains coarser fragments. Types Cataclasites are composed of fragments of the pre-existing wall rock as well as a matrix consisting of crushed microfragments, which cohesively holds the rock together. There are different types of classification schemes for cataclasites in the fault rock literature. The original classification scheme by Sibson classifies them by their proportion of fine-grained matrix to angular fragments. The term fault breccia is used for describing a cataclasite with coarser grains. A fault breccia is a cataclastic rock with clasts that are larger than two millimeters making up at least 30% of the rock. These ...
