Peary Glacier
Peary Glacier ( da, Peary Gletscher), is a glacier in north west Greenland. Administratively it belongs to the Avannaata municipality. This glacier was named after US Arctic explorer Robert Peary (1856 - 1920). Geography The Peary Glacier is located in the Lauge Koch Coast, Melville Bay. It originates in the western Greenland ice sheet and flows southwestwards between the Rink Glacier to the northwest and the King Oscar Glacier to the southeast. Its terminus lies east of Cape Murdoch, northeast of the Balgoni Islands and Thalbitzer Næs in Melville Bay.GoogleEarth Unlike the neighboring King Oscar Glacier, it does not produce many icebergs.''Prostar Sailing Directions 2005 Greenland and Iceland Enroute'', p. 84 See also *List of glaciers in Greenland This is a list of glaciers in Greenland.

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 ...

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.

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 ...

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] |
Cape Murdoch (Greenland)
Cape Murdoch ( da, Kap Murdoch) is a headland ih1> Geography Cape Murdoch is located at the southern end of an unnamed island north of Heilprin Island in Melville Bay. The cape lies in an area of small islands at the northern limits of Melville Bay to the west of the Fisher Islands and WNW of Thalbitzer Næs, near the terminuses of the Docker Smith Glacier and the Rink Glacier. The terminus of the Peary Glacier lies to the east.

Glacier Terminus
A glacier terminus, toe, or snout, is the end of a glacier at any given point in time. Although glaciers seem motionless to the observer, in reality glaciers are in endless motion and the glacier terminus is always either advancing or retreating. The location of the terminus is often directly related to glacier mass balance, which is based on the amount of snowfall which occurs in the accumulation zone of a glacier, as compared to the amount that is melted in the ablation zone. The position of a glacier terminus is also impacted by localized or regional temperature change over time. Tracking Tracking the change in location of a glacier terminus is a method of monitoring a glacier's movement. The end of the glacier terminus is measured from a fixed position in neighboring bedrock periodically over time. The difference in location of a glacier terminus as measured from this fixed position at different time intervals provides a record of the glacier's change. A similar way of trac ...

Rink Glacier (Melville Bay)
Rink Glacier ( da, Rink Gletscher), is a glacier in NW Greenland. Administratively it belongs to the Avannaata municipality.

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'', ...

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 ...
