Ferguson Lake (Kitikmeot Region)
Tahiryuaq, formerly Ferguson Lake, (Inuinnaqtun: ') is located on southern Victoria Island in the Kitikmeot Region of Nunavut, in northern Canada. It drains westward into Iqaluktuuq (meaning "place of big fish") which is a segment of the Ekalluk River, from the northeastern side of Wellington Bay (''Ekaloktok''), on Dease Strait, Arctic Ocean Ferguson Lake was the namesake of Constable Ferguson, a Royal Canadian Mounted Police member, but is now known by the original name of Tahiryuaq Tahiryuaq has been characterized as "polar semi-desert". Its fauna includes willow-sedge meadows, dryas uplands, and raised beaches. The narrow land area between Wellington Bay and Tahiryuaq funnels migrating Dolphin-Union caribou herd, making them easy prey for Inuit hunters. Muskox, Arctic hare, and ptarmigan also inhabit the area. The lake itself contains Arctic char (''iqalukpiit'') and lake trout (''ihuurayuit''). These were the principal food sources for Copper Inuit who were predated by p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sentinel-2
Sentinel-2 is an Earth observation mission from the Copernicus Programme that systematically acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters. The mission is currently a constellation with two satellites, Sentinel-2A and Sentinel-2B; a third satellite, Sentinel-2C, is currently undergoing testing in preparation for launch in 2024. The mission supports a broad range of services and applications such as agricultural monitoring, emergencies management, land cover classification or water quality. Sentinel-2 has been developed and is being operated by the European Space Agency, and the satellites were manufactured by a consortium led by Airbus Defence and Space in Friedrichshafen. Overview The Sentinel-2 mission has the following key characteristics: * Multi-spectral data with 13 bands in the visible, near infrared, and short wave infrared part of the spectrum * Systematic global coverage of land surfaces from 56° S to 84°&nb ...

Dolphin-Union Caribou
Dolphin and Union Caribou, Dolphin and Union caribou herd, Dolphin-Union, locally known as Island Caribou, are a migratory population of barren-ground caribou, ''Rangifer tarandus groenlandicus,'' that occupy Victoria Island in the Canadian Arctic Archipelago and the nearby mainland. They are endemic to Canada. They migrate across the Dolphin and Union Strait from their summer grazing on Victoria Island to their winter grazing area on the Nunavut-Northwest Territories mainland in Canada. It is unusual for North American caribou to seasonally cross sea ice and the only other caribou to do so are the Peary caribou who are smaller in size and population. They were listed as Endangered by Committee on the Status of Endangered Wildlife in Canada (COSEWIC) since November 2017. Morphology Pelage The pelage of the Dolphin and Union Caribou is white in winter and slate-grey with white legs and under-parts in summer like the Peary caribou. The Dolphin and Union Caribou are slightly darke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lakes Of Kitikmeot Region
A lake is an area filled with water, localized in a Depression (geology), basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the World Ocean, ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glacier, glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic dra ...

Northern Canada
Northern Canada, colloquially the North or the Territories, is the vast northernmost region of Canada variously defined by geography and politics. Politically, the term refers to the three Provinces_and_territories_of_Canada#Territories, territories of Canada: Yukon, Northwest Territories and Nunavut. This area covers about 48 per cent of Canada's total land area, but has less than 1 per cent of demographics of Canada, Canada's population. The terms "northern Canada" or "the North" may be used in contrast with ''the far north'', which may refer to the Canadian Arctic, the portion of Canada that lies north of the Arctic Circle, east of Alaska and west of Greenland. However, in many other uses the two areas are treated as a single unit. __TOC__ Definitions Subdivisions As a social rather than political region, the Canadian North is often subdivided into two distinct regions based on climate, the ''near north'' and the ''far north''. The different climates of these two regions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thule People
The Thule (, , ) or proto-Inuit were the ancestors of all modern Inuit. They developed in coastal Alaska by the year 1000 and expanded eastward across northern Canada, reaching Greenland by the 13th century. In the process, they replaced people of the earlier Dorset culture that 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. The links between the Thule and the Inuit are biological, cultural, and linguistic. Evidence supports the idea that the Thule (and also the Dorset, but to a lesser degree) were in contact with the Vikings, who had reached the shores of Canada in the 11th century as part of 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". ...

Dorset Culture
The Dorset was a Paleo-Eskimo culture, lasting from to between and , that followed the Pre-Dorset and preceded the Thule people (proto-Inuit) in the North American Arctic. The culture and people are named after Cape Dorset (now Kinngait) in Nunavut, Canada, where the first evidence of its existence was found. The culture has been defined as having four phases due to the distinct differences in the technologies relating to hunting and tool making. Artifacts include distinctive triangular end-blades, oil lamps () made of soapstone, and burins. The Dorset were first identified as a separate culture in 1925. The Dorset appear to have been extinct by 1500 at the latest and perhaps as early as 1000. The Thule people, who began migrating east from Alaska in the 11th century, ended up spreading through the lands previously inhabited by the Dorset. There is no strong evidence that the Inuit and Dorset ever met. Modern genetic studies show the Dorset population were distinct from later ...

Copper Inuit
Copper Inuit, also known as Kitlinermiut and Inuinnait, are a Canadian Inuit group who live north of the tree line, in what is now the Kitikmeot Region of Nunavut and in the Inuvialuit Settlement Region in the Inuvik Region of the Northwest Territories. Most of them historically lived in the area around Coronation Gulf, on Victoria Island, and southern Banks Island. Their western boundary was Wise Point, near Dolphin and Union Strait. Their northwest territory was the southeast coast of Banks Island. Their southern boundary was the eastern shore of Great Bear Lake, Contwoyto Lake and Lake Beechey on the Back River. To the east, the Copper Inuit and the Netsilingmiut were separated by Perry River in Queen Maud Gulf. While Copper Inuit travelled throughout Victoria Island, to the west, they concentrated south of Walker Bay, while to the east, they were concentrated south of Denmark Bay. As the people have no collective name for themselves, they have adopted the English term "C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Trout
The lake trout (''Salvelinus namaycush'') is a freshwater char living mainly in lakes in northern North America. Other names for it include mackinaw, namaycush, lake char (or charr), touladi, togue, and grey trout. In Lake Superior, it can also be variously known as siscowet, paperbelly and lean. The lake trout is prized both as a game fish and as a food fish. Those caught with dark coloration may be called ''mud hens''. Taxonomy It is the only member of the subgenus ''Cristovomer'', which is more derived than the subgenus '' Baione'' (the most basal clade of ''Salvelinus'', containing the brook trout (''S. fontinalis'') and silver trout (''S. agasizii'')) but still basal to the other members of ''Salvelinus''. Range From a zoogeographical perspective, lake trout have a relatively narrow distribution. They are native only to the northern parts of North America, principally Canada, but also Alaska and, to some extent, the northeastern United States. Lake trout have been wide ...

Arctic Char
The Arctic char or Arctic charr (''Salvelinus alpinus'') is a cold-water fish in the family Salmonidae, native to alpine lakes and arctic and subarctic coastal waters. Its distribution is Circumpolar North. It spawns in freshwater and populations can be lacustrine, riverine, or anadromous, where they return from the ocean to their fresh water birth rivers to spawn. No other freshwater fish is found as far north; it is, for instance, the only fish species in Lake Hazen which extend up to on Ellesmere Island in the Canadian Arctic. It is one of the rarest fish species in Great Britain and Ireland, found mainly in deep, cold, glacial lakes, and is at risk there from acidification. In other parts of its range, such as the Nordic countries, it is much more common, and is fished extensively. In Siberia, it is known as ''golets'' () and it has been introduced in lakes where it sometimes threatens less hardy endemic species, such as the small-mouth char and the long-finned char ...

Rock Ptarmigan
The rock ptarmigan (''Lagopus muta'') is a medium-sized game bird in the grouse family. It is known simply as the ptarmigan in the UK. It is the official bird for the Canadian territory of Nunavut, where it is known as the ''aqiggiq'' (ᐊᕿᒡᒋᖅ), and the official game bird for the province of Newfoundland and Labrador. In Japan, it is known as the ''raichō'' (雷鳥), which means "thunder bird". It is the official bird of Gifu, Nagano, and Toyama Prefectures and is a protected species nationwide. Unlike many arctic bird species, ptarmigan do not gain substantial mass to hibernate over winter. Etymology The ptarmigan's genus name, ''Lagopus'', is derived from Ancient Greek ''lagos'' (λαγώς ''lagṓs''), meaning "hare", + ''pous'' (πούς ''poús''), "foot", in reference to the bird's feathered legs. The species name, ''muta'', comes from New Latin and means "mute", referring to the simple croaking song of the male. It was for a long time misspelt ''mutus'', in the ...
