J. A. D. Jensen Nunataks
J. A. D. Jensen Nunataks ( da, J. A. D. Jensen Nunatakker) are a nunatak group in Greenland. Administratively it falls under the Sermersooq Municipality.

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] |

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'', ...

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] |
Jens Arnold Diderich Jensen
Jens Arnold Diderich Jensen (24 July 1849, in Flensburg – 24 November 1936, in Copenhagen) was a Denmark, Danish naval officer and Arctic explorer. Career Jensen assisted the geology, geological exploration along the Greenland west coast. He is particularly renowned for his explorations of the inland ice sheet. He led an expedition that discovered the nunataks now named J. A. D. Jensen Nunataks ''(J. A. D. Jensens Nunatakker)'' after him. The geologist of the expedition, A. Kornerup, collected no less than 27 species of Angiosperms on the nunataks. Cape J.A.D. Jensen and the J.A.D. Jensen Fjord are also named after him. In 1911, he changed his name to Jens Arnold Diderich Jensen Bildsøe.

Meddelelser Om Grønland
''Meddelelser om Grønland'' ("''Communications on Greenland''") is a Danish scientific periodical which publishes scientific results from all fields of research on Greenland. It was established by Frederik Johnstrup and published as a single series by the Commission for Scientific Investigations in Greenland from 1878 to 1979, with contributions in Danish, German, English or French. In 1979, following the issue of vol. 206, the series was split up into three individually numbered subseries, all published in English: ''Bioscience'', ''Geoscience'', and ''Man & Society''. When publication of the series was handed over to Museum Tusculanum Press Museum Tusculanum Press (Danish: ''Museum Tusculanums Forlag'') is an independent academic press historically associated with the University of Copenhagen, publishing mainly in the humanities, social sciences and theology. It was founded in 1975 as ... in 2008, the original name was revived, now with the official English title ''Monographs o ... [...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 ...

Polar Climate
The polar climate regions are characterized by a lack of warm summers but with varying winters. Every month in a polar climate has an average temperature of less than . Regions with polar climate cover more than 20% of the Earth's area. Most of these regions are far from the equator and near the poles, and in this case, winter days are extremely short and summer days are extremely long (could last for the entirety of each season or longer). A polar climate consists of cool summers and very cold winters, which results in treeless tundra, glaciers, or a permanent or semi-permanent layer of ice. It is identified with the letter E in the Köppen climate classification. Subtypes There are two types of polar climate: ET, or tundra climate; and EF, or ice cap climate. A tundra climate is characterized by having at least one month whose average temperature is above , while an ice cap climate has no months averaging above . In a tundra climate, even coniferous trees cannot grow, but o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
