Lake Hazen
Lake Hazen is a freshwater lake in the northern part of Ellesmere Island, Nunavut, Canada, north of the Arctic Circle. It is the largest lake north of the Arctic Circle by volume. By surface area it is third largest, after Lake Taymyr in Russia and Lake Inari in Finland. The area around the lake is a thermal oasis within a polar desert, with summer temperatures up to . The lake itself is covered by ice about ten months a year. It is fed by glaciers (most importantly Henrietta Nesmith and the Gilmour Glaciers) from the surrounding Eureka Uplands—Palaeozoic rocks north of the lake, rising up to above sea level—and drained by the Ruggles River, which flows into Chandler Fjord on the northern east coast of Ellesmere Land. The lake is flanked by the Arctic Cordillera. The lake is long and up to wide, with an area of .Mark Nuttal: ''Encyclopedia of the Artctic''.

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 ...

Thule People
The Thule ( , ) or proto-Inuit were the ancestors of all modern Inuit. They developed in coastal Alaska by 1000 AD and expanded eastward across northern Canada, reaching Greenland by the 13th century. In the process, they replaced people of the earlier Dorset culture who had previously inhabited the region. The appellation " Thule" originates from the location of Thule (relocated and renamed Qaanaaq in 1953) in northwest Greenland, facing Canada, where the archaeological remains of the people were first found at Comer's Midden. Evidence supports the idea that the Thule (and, to a lesser degree, the Dorset) were in contact with the Vikings, who had reached the shores of Canada in the 11th century as part of the Norse colonization of North America. In Viking sources, these peoples are called the '' Skrælingjar''. Some Thule migrated southward, in the "Second Expansion" or "Second Phase". By the 13th or 14th century, the Thule had occupied an area inhabited until then by the D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arctic Ocean
The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. It spans an area of approximately and is the coldest of the world's oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. It has also been described as an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing world ocean. The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere and extends south to about 60°N. The Arctic Ocean is surrounded by Eurasia and North America, and the borders follow topographic features: the Bering Strait on the Pacific side and the Greenland Scotland Ridge on the Atlantic side. It is mostly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is the ...

Lincoln Sea
Lincoln Sea (; ) is a body of water in the Arctic Ocean, stretching from Cape Columbia, Canada, in the west to Cape Morris Jesup, Greenland, in the east.

Water depths range from to . Water and ice from Lincoln Sea empty into Robeson Channel, the northernmost part of Nares Strait, most of the time. The sea was named after Robert Todd Lincoln, then United States Secretary of War, on Adolphus W. Greely's 1881–1884 Arctic expedition into Lady Franklin Bay. Alert, the northernmost station of Canada, is the only populated place on the shore of Lincoln Sea. The body of water to the east of Lincoln Sea (east of Cape Morris Jesup) is the Wandel Sea.

Lake
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of ocean ...
