Orsugissap Qaqqarsua
Orsugissap Qaqqarsua (old spelling: ''Orssugissap Qaqqarssua'') is a nunatak ( kl, nunataq) of the Greenland ice sheet in Avannaata municipality in northwestern Greenland. Geography Orsugissap Qaqqarsua () is located on the mainland of Greenland in the northern part of Upernavik Archipelago. Due to the glacial retreat, it is now conjoint in the north with Anoritooq, a nunatak.''Upernavik Avannarleq'', Saga Map, Tage Schjøtt, 1992 To the west and south, the nunatak is surrounded by the waters of Sugar Loaf Bay Sugar Loaf Bay is a bay in the Upernavik Archipelago in the Avannaata municipality in northwestern Greenland. It is an indentation of northeastern Baffin Bay. The name of the bay derives from the name of an island of the same name in the bay, Sug ..., and its innermost inlets, the largest of which is ''Niaqornarsuup Iterlaa'' in the south.

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] |
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 ...

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.

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'', ...

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] |
Retreat Of Glaciers Since 1850
The retreat of glaciers since 1850 affects the availability of fresh water for irrigation and domestic use, mountain recreation, animals and plants that depend on glacier-melt, and, in the longer term, the level of the oceans. Deglaciation occurs naturally at the end of ice ages, but glaciologists find the current glacier retreat is accelerated by the measured increase of atmospheric greenhouse gases—an effect of climate change. Mid-latitude mountain ranges such as the Himalayas, Rockies, Alps, Cascades, Southern Alps, and the southern Andes, as well as isolated tropical summits such as Mount Kilimanjaro in Africa, are showing some of the largest proportionate glacial losses. Excluding peripheral glaciers of ice sheets, the total cumulated global glacial losses over the 26 year period from 1993–2018 were likely 5500 gigatons, or 210 gigatons per yr.Fox-Kemper, B., H.T.

Anoritooq
Anoritooq (old spelling: ''Anoritôq'') is a nunatak ( kl, nunataq) in Avannaata municipality in northwestern Greenland.

Sugar Loaf Bay
Sugar Loaf Bay is a bay in the Upernavik Archipelago in the Avannaata municipality in northwestern Greenland. It is an indentation of northeastern Baffin Bay. The name of the bay derives from the name of an island of the same name in the bay, Sugar Loaf Island ( kl, Uummannaq, not to be confused with Uummannaq Island). Geography The bay is located in the northern part of Upernavik Archipelago, between Qullikorsuit Island in the south and Nuussuaq Peninsula in the north.''Upernavik Avannarleq'', Saga Map, Tage Schjøtt, 1992 At its widest − from the ''Nuussuup Nuua'' promontory on Nuussuaq Peninsula to the ''Nuussua'' cape on Kittorsaq Island − Sugar Loaf Bay stretches for . The length of the bay reaches its maximum of at the point where the Greenland ice sheet ( kl, Sermersuaq) drains into the bay via Cornell Glacier. Islands There are several islands and skerries in the bay, scattered over the entire area of the bay. Amitsorsuaq Island is the largest island in the b ...
