Tidewater Glacier
The tidewater glacier cycle is the typically centuries-long behavior of tidewater glaciers that consists of recurring periods of advance alternating with rapid retreat and punctuated by periods of stability. During portions of its cycle, a tidewater glacier is relatively insensitive to climate change. Calving rate of tidewater glaciers While climate is the main factor affecting the behavior of all glaciers, additional factors affect calving (iceberg-producing) tidewater glaciers. These glaciers terminate abruptly at the ocean interface, with large pieces of the glacier fracturing and separating, or calving, from the ice front as icebergs. Climate change causes a shift in the equilibrium line altitude (ELA) of a glacier. This is the imaginary line on a glacier, above which snow accumulates faster than it ablates, and below which, the reverse is the case. This altitude shift, in turn, prompts a retreat or advance of the terminus toward a new steady-state position. However, this ch ...

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'', ...

Melville Bay
Melville Bay ( kl, Qimusseriarsuaq; da, Melville Bugt), is a large bay off the coast of northwestern Greenland. Located to the north of the Upernavik Archipelago, it opens to the south-west into Baffin Bay. Its Kalaallisut name, ''Qimusseriarsuaq'', means "the great dog sledding place". The bay was named after Robert Dundas, 2nd Viscount Melville, (1771 - 1851) head of the Admiralty. Geography Melville Bay is delimited by Cape York in the northeast and Wilcox Head, the western promontory on Kiatassuaq Island in the south.''Upernavik Avannarleq'', Saga Map, Tage Schjøtt, 1992 Some islands of the Upernavik Archipelago are in the Melville Bay area, such as Kiatassuaq Island, Kullorsuaq Island, Saarlia Island and Saqqarlersuaq Island. Melville Bay is free of fast ice between mid August and the end of September on average. Navigation is dangerous as there are numerous icebergs in the bay throughout the year.''Prostar Sailing Directions 2005 Greenland and Iceland Enroute,'' p. 8 ...

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.

Avannaata
Avannaata (, da, Det Nordlige, lit=The Northern) is a municipality of Greenland created on 1 January 2018 from the bulk of the former Qaasuitsup municipality. It encompasses an area of 522,700 km2 and has 10,726 inhabitants. Geography In the south, Avannaata is flanked by the Qeqertalik municipality. In the southeast, it is bordered by the Sermersooq municipality, however this border runs north–south ( 45° West meridian) through the center of the Greenland ice sheet ( kl, Sermersuaq), and as such is free of traffic. In the east and northeast it is bordered by the Northeast Greenland National Park. At the southern end of the municipal coastline are the waters of Disko Bay, although some Disko Bay communities belong to the municipality of Qeqertalik. This bay is an inlet of the larger Baffin Bay, which to the north edges into the island of Greenland in the form of Melville Bay. The coastline of northeastern Baffin Bay is dotted with islands of the Upernavik Archipela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Upernavik Archipelago
Upernavik Archipelago is a vast coastal archipelago in the Avannaata municipality in northwestern Greenland, off the shores of northeastern Baffin Bay. The archipelago extends from the northwestern coast of Sigguup Nunaa peninsula in the south at approximately Nunavik, Saga Map, 1:250.000, Tage Schjøtt, 1992 to the southern end of Melville Bay ( kl, Qimusseriarsuaq) in the north at approximately .Upernavik Avannarleq, Saga Map, 1:250.000, Tage Schjøtt, 1992 History The archipelago belongs to the earliest-settled areas of Greenland, the first migrants arriving approximately 2,000 BCE. All southbound migrations of the Inuit passed through the area, leaving behind a trail of archeological sites. The early Saqqaq culture diminished in importance around 1,000 BCE, followed by the migrants of Dorset culture, who spread alongside the coast of Baffin Bay, being in turn displaced by the Thule people in the 13th and 14th centuries. The area has been continuously inhabited since then. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenland Ice Sheet
The Greenland ice sheet ( da, Grønlands indlandsis, kl, Sermersuaq) is a vast body of ice covering , roughly near 80% of the surface of Greenland. It is sometimes referred to as an ice cap, or under the term ''inland ice'', or its Danish equivalent, ''indlandsis''. An acronym, GIS, is frequently used in the scientific literature. It is the second largest ice body in the world, after the Antarctic ice sheet. The ice sheet is almost long in a north–south direction, and its greatest width is at a latitude of 77°N, near its northern margin. The average thickness is about and over at its thickest point. In addition to the large ice sheet, smaller ice caps (such as Maniitsoq and Flade Isblink) as well as glaciers, cover between around the periphery. The Greenland ice sheet is adversely affected by climate change. It is more vulnerable to climate change than the Antarctic ice sheet because of its position in the Arctic, where it is subject to the regional amplification o ...

King Oscar Glacier
King Oscar Glacier ( da, Kong Oscar Gletscher) is a large glacier in the Avannaata Municipality, on the northwestern coast of Greenland. Geography The King Oscar Glacier is one of several glaciers that drain the north-western part of the Greenland Ice Sheet into Melville Bay. It flows roughly southwestwards between the Peary Glacier to the northwest and the Nordenskiold Glacier to the southeast. Status As part of a comprehensive survey of Greenland's glaciers that was published in 2006, scientists documented that the mass balance—the sum of gains through snow accumulation and losses through iceberg calving and melting—of Kong Oscar and Greenland's other north-western glaciers was strongly negative between 1996 and 2005: they lost more ice than they gained. The pattern was similar to the ice sheet as a whole, which has been losing ice mass at an accelerating pace in the past decade.

Sverdrup Glacier
In oceanography, the sverdrup (symbol: Sv) is a non-International System of Units, SI Metric_units#Volume_flow_rate, metric unit of volumetric flow rate, with equal to . It is equivalent to the SI derived unit cubic hectometer per second (symbol: hm3/s or hm3⋅s−1): 1 Sv is equal to 1 hm3/s. It is used almost exclusively in oceanography to measure the volumetric rate of transport of ocean currents. It is named after Harald Sverdrup (oceanographer), Harald Sverdrup. One sverdrup is about five times what is carried by the world’s largest river, the Amazon. In the context of ocean currents, a volume of one million cubic meters may be imagined as a "slice" of ocean with dimensions × × (width × length × thickness). At this scale, these units can be more easily compared in terms of width of the current (several km), depth (hundreds of meters), and current speed (as velocity, meters per second). Thus, a hypothetical current wide, 500 m (0.5 km) deep, and moving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operational Navigation Chart B-8, 3rd 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 ...
