Trefork Lake
Trefork Lake (), is a lake in King Frederik VIII Land, Northeastern Greenland. The lake and its surroundings are part of the Northeast Greenland National Park zone. The Danish weather station Danmarkshavn —the only inhabited place in the area— lies about to the east. History The lake was named "Trident Lake" () by the 1952–54 British North Greenland expedition because of its shape. Geography Trefork Sø is the largest lake in the northern part of Queen Louise Land. The lake is located between the large Admiralty and Borgjokel glaciers. The terminus of the smaller Trefork Glacier is at the southwestern end. The Ad Astra Ice Cap rises to the northeast.

Sentinel-2
Sentinel-2 is an Earth observation mission from the Copernicus Programme that acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters. The mission's Sentinel-2A and Sentinel-2B satellites were joined in orbit in 2024 by a third, Sentinel-2C, and in the future by Sentinel-2D, eventually replacing the A and B satellites, respectively. The mission supports services and applications such as agricultural monitoring, emergencies management, land cover classification, and water quality. Sentinel-2 has been developed and is being operated by the European Space Agency. The satellites were manufactured by a consortium led by Airbus Defence and Space in Friedrichshafen, Germany. Overview The Sentinel-2 mission includes: * Multispectral image, Multi-spectral data with 13 bands in the Visible spectrum, visible, Infrared#Regions within the infrared, near infrared, and Infrared#Regions within the infrared, short wave infrared part of the Electromagnetic ...

Weather Station
A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmosphere of Earth, atmospheric conditions to provide information for weather forecasting, weather forecasts and to study the weather and climate. The measurements taken include temperature, atmospheric pressure, humidity, wind speed, wind direction, and precipitation amounts. Wind measurements are taken with as few other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once daily, while automated measurements are taken at least once an hour. Weather conditions out at sea are taken by ships and buoys, which measure slightly different meteorological quantities such as sea surface temperature (SST), wave height, and wave period. Drifting weather buoys outnumber their moored versions by a significant amount. Weather instruments A weather instrument is any device t ...

Ad Astra Ice Cap
Advertising is the practice and techniques employed to bring attention to a product or service. Advertising aims to present a product or service in terms of utility, advantages, and qualities of interest to consumers. It is typically used to promote a specific good or service, but there are a wide range of uses, the most common being commercial advertisement. Commercial advertisements often seek to generate increased consumption of their products or services through "branding", which associates a product name or image with certain qualities in the minds of consumers. On the other hand, ads that intend to elicit an immediate sale are known as direct-response advertising. Non-commercial entities that advertise more than consumer products or services include political parties, interest groups, religious organizations, and governmental agencies. Non-profit organizations may use free modes of persuasion, such as a public service announcement. Advertising may also help to reas ...

Admiralty Glacier
Admiralty Glacier () is a glacier in Queen Louise Land, northeastern Greenland.Google Earth Administratively it belongs to the Northeast Greenland National Park. History The glacier was mapped during the 1952–54 British North Greenland expedition led by Commander James Simpson. It was named after the British Admiralty in order to commemorate the assistance given to the expedition by the Royal Navy. Geography The Admiralty Glacier is one of the main glaciers in northern Queen Louise Land. It flows from the Greenland Ice Sheet from west to east the first , slightly bending to the north of Trefork Lake and flowing roughly northeastwards. The Ad Astra Ice Cap lies to the east of its lower stretch. The glacier has its terminus in the Støvdal valley at the Britannia Lake, near the southern end of the Britannia Glacier. The structure of the cliffs on either side of Admiralty Glacier was examined by the British North Greenland expedition geologists. Expedition member and g ...

British North Greenland Expedition
The British North Greenland expedition was a British scientific mission, led by Commander James Simpson RN, which lasted from July 1952 to August 1954. A total of 30 men took part, though not all stayed for both years. The purpose of BNGE was primarily to carry out scientific studies in glaciology, meteorology, geology and physiology. Gravimetric and seismological surveys were made, and radio wave propagation was also studied from their station codenamed " North Ice". It also provided information useful to the Armed Forces about operating in Arctic environments, and the majority of the team were serving members. Travel over the icecap was either on foot, by dog sled, or by M29 Weasel tracked vehicles. Expedition members also made pioneering ascents in the Barth Mountains and Queen Louise Land. History Simpson made a preparatory exploration in 1951. A Short Sunderland flying boat landed in Seal Lake and from there Simpson walked across Storstrommen to Queen Louise Land. Th ...

Danmarkshavn
Danmarkshavn (Denmark's Harbour) is a small weather station located in Dove Bay, on the northeastern shore of the Germania Land Peninsula, in Northeast Greenland National Park, Greenland. History The location was chosen as a suitable winter harbor by the Denmark expedition in 1906 for their ship Danmark (1906), ''Danmark''. It became the main base of the expedition, from where sledge journeys and scientific observations were carried out. Description The permanent population of the base is six. Danmarkshavn is also known as the northernmost location on the coast of the Greenland Sea that non-icebreaking vessels can pass through. Therefore, it is resupplied by cargo ship in August every other year; thus the population increases somewhat for a brief time every other August. The ice situation varies, and some years it is not possible to reach the station, other years it is ice-free further north. It is operated by TELE Greenland, ''TELE-POST Greenland'', a telecommunications company. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northeast Greenland National Park
Northeast Greenland National Park (, ) is the world's largest national park and the 10th largest protected area (the only larger protected areas consist mostly of sea). Established in 1974, the Northeast Greenland national park expanded to its present size in 1988. It protects of the interior and northeastern coast of Greenland and is larger than the area of Tanzania, but smaller than that of Egypt. This means that the national park is bigger than 166 of the world's 195 countries. It was the first national park to be created in the Kingdom of Denmark and remains Greenland's only national park. It is the northernmost national park in the world and the second-largest by area of any second-level subdivision of any country in the world, trailing only the Qikiqtaaluk Region in Nunavut, Canada. Geography The park shares borders, largely laid out as straight lines, with the Sermersooq municipality in the south and with the Avannaata municipality in the west, partly along the 45° ...

Queen Louise Land
Queen Louise Land (; ) is a vast mountainous region located west of Dove Bay, King Frederik VIII Land, northeastern Greenland. Administratively it is part of the Northeast Greenland National Park zone. The highest point of Queen Louise Land is Gefiontinde, with a height of , the highest of the Gefiontinder group of peaks located at .Google Earth Geologically Queen Louise Land is made up of orthogneiss overlain by sedimentary rocks. History This remote area was named ''Dronning Louises Land'' after Queen Louise of Denmark (1851–1926), wife of King Frederik VIII of Denmark, by the ill-fated 1906–08 Denmark Expedition —the expedition that aimed to map one of the last unknown parts of Greenland. Danish Arctic explorer Alf Trolle claimed that this area had been originally named as ''Den Store Nanuták'' —The Big Nunatak.

King Frederik VIII Land
King Frederik VIII Land (; ) is a major geographic division of northeastern Greenland. It extends above the Arctic Circle from 76°N to 81°N in a North-South direction along the coast of the Greenland Sea. History This vast desolate region was still uncharted territory around 1900. It was explored by the 1906–08 Denmark Expedition, the 1909–12 Alabama Expedition and by J.P. Koch's 1912–13 Danish Expedition to Queen Louise Land, when the ruling monarch was Frederik VIII (1843–1912). The area between 79° and 81°30´N was first marked as 'King Frederik VIII Land', after King Frederik VIII of Denmark then the ruling monarch, by the 1906–08 Denmark Expedition in its maps of the region. Einar Storgaard used the name again in a 1927 map, and he also proposed a division of the region into a northern and a southern part with a border along Nioghalvfjerd Fjord. Finally the name came into general usage only after the publication of the 1931–34 Three-year Expedition to E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
