Lancaster Sound
Lancaster Sound () is a body of water in the Qikiqtaaluk Region, Nunavut, Canada. It is located between Devon Island and Baffin Island, forming the eastern entrance to the Parry Channel and the Northwest Passage. East of the sound lies Baffin Bay; to the west lies Viscount Melville Sound. Further west a traveller would enter the M'Clure Strait before heading into the Arctic Ocean. The Inuit and their predecessors in the region, the Paleo-Eskimos, have relied for hundreds, perhaps thousands of years on the sound's abundant natural wealth for food, clothing and shelter. Today, residents of the three Nunavut communities of Pond Inlet, Arctic Bay, and Resolute continue this tradition, depending on its waters for their economic and cultural well being. History Lancaster Sound was named in 1616 by explorer William Baffin for Sir James Lancaster, one of the three main financial supporters of his exploratory expeditions. The abortive expedition by the British explorer John Ross in 181 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qikiqtaaluk Region
The Qikiqtaaluk Region, Qikiqtani Region (Inuktitut syllabics: ᕿᑭᖅᑖᓗᒃ ) or Baffin Region is the easternmost, northernmost, and southernmost administrative region of Nunavut, Canada. Qikiqtaaluk is the traditional Inuktitut name for Baffin Island. Although the Qikiqtaaluk Region is the most commonly used name in official contexts, several notable public organizations, including Statistics Canada prefer the older term Baffin Region. With a population of 18,988 and an area of , it is the largest and most populated of the three regions. The region consists of Baffin Island, the Belcher Islands, Akimiski Island, Mansel Island, Prince Charles Island, Bylot Island, Devon Island, Baillie-Hamilton Island, Cornwallis Island, Bathurst Island, Amund Ringnes Island, Ellef Ringnes Island, Axel Heiberg Island, Ellesmere Island, the Melville Peninsula, the eastern part of Melville Island, and the northern parts of both Prince of Wales Island and Somerset Island, plus s ...

Resolute, Nunavut
Resolute or Resolute Bay ( iu, ᖃᐅᓱᐃᑦᑐᖅ, translit=Qausuittuq, lit=place with no dawn, italic=no) is an Inuit hamlet on Cornwallis Island in Nunavut, Canada. It is situated at the northern end of Resolute Bay and the Northwest Passage and is part of the Qikiqtaaluk Region. Resolute is one of Canada's northernmost communities and is second only to Grise Fiord on Ellesmere Island ( Alert and Eureka are more northerly but are not considered towns; rather, military outposts and weather stations). It is also one of the coldest inhabited places in the world, with an average yearly temperature of . As in most other northern communities, the roads and most of the terrain are all gravel. It is also the closest transit location to Devon Island, the largest uninhabited island in the world, and by extension, the most well-preserved crater on Earth - the Haughton impact crater, that formed about 31 million years ago.

Ringed Seal
The ringed seal (''Pusa hispida'') is an earless seal inhabiting the Arctic and sub-Arctic regions. The ringed seal is a relatively small seal, rarely greater than 1.5 m in length, with a distinctive patterning of dark spots surrounded by light gray rings, hence its common name. It is the most abundant and wide-ranging ice seal in the Northern Hemisphere, ranging throughout the Arctic Ocean, into the Bering Sea and Okhotsk Sea as far south as the northern coast of Japan in the Pacific and throughout the North Atlantic coasts of Greenland and Scandinavia as far south as Newfoundland, and including two freshwater subspecies in northern Europe. Ringed seals are one of the primary prey of polar bears and killer whales, and have long been a component of the diet of indigenous people of the Arctic. Ringed seals are the smallest and most abundant member of the seal family that live in the Arctic and Sub-Arctic regions. The average life span of a ringed seal is 40 years, with a diet b ...

Bowhead Whale
The bowhead whale (''Balaena mysticetus'') is a species of baleen whale belonging to the family Balaenidae and the only living representative of the genus ''Balaena''. They are the only baleen whale endemic to the Arctic and subarctic waters, and are named after their characteristic massive triangular skull, which they use to break through Arctic ice. Other common names of the species are the Greenland right whale, Arctic whale, and Arviq in aboriginal languages ( Inuktitut). American whalemen called them the steeple-top, polar whale, or Russian whale. Bowheads have the largest mouth of any animal representing almost one-third of the length of the body, the longest baleen plates with a maximum length of and may be the longest-lived mammals, with the ability to reach an age of more than 200 years. The bowhead was an early whaling target. Their population was severely reduced before a 1966 moratorium was passed to protect the species. Of the five stocks of bowhead population ...

Beluga Whale
The beluga whale () (''Delphinapterus leucas'') is an Arctic and sub-Arctic cetacean. It is one of two members of the family Monodontidae, along with the narwhal, and the only member of the genus ''Delphinapterus''. It is also known as the white whale, as it is the only cetacean to regularly occur with this colour; the sea canary, due to its high-pitched calls; and the melonhead, though that more commonly refers to the melon-headed whale, which is an oceanic dolphin. The beluga is adapted to life in the Arctic, with anatomical and physiological characteristics that differentiate it from other cetaceans. Amongst these are its all-white colour and the absence of a dorsal fin, which allows it to swim under ice with ease. It possesses a distinctive protuberance at the front of its head which houses an animal echolocation, echolocation organ called the Melon (whale), melon, which in this species is large and deformable. The beluga's body size is between that of a dolphin and a true ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narwhal
The narwhal, also known as a narwhale (''Monodon monoceros''), is a medium-sized toothed whale that possesses a large "tusk" from a protruding canine tooth. It lives year-round in the Arctic waters around Greenland, Canada and Russia. It is one of two living species of whale in the family Monodontidae, along with the beluga whale, and the only species in the genus ''Monodon''. The narwhal males are distinguished by a long, straight, helical tusk, which is an elongated upper left canine. The narwhal was one of many species described by Carl Linnaeus in his publication ''Systema Naturae'' in 1758. Like the beluga, narwhals are medium-sized whales. For both sexes, excluding the male's tusk, the total body size can range from ; the males are slightly larger than the females. The average weight of an adult narwhal is . At around 11 to 13 years old, the males become sexually mature; females become sexually mature at about 5 to 8 years old. Narwhals do not have a dorsal fin and thei ...

Arctogadus Glacialis
''Arctogadus glacialis'', known also with ambiguous common names Arctic cod and polar cod, is an Arctic species of fish in the cod family Gadidae, related to the true cod (genus ''Gadus''). ''Arctogadus glacialis'' is found in icy water. They grow to about 30 cm long, and are favorite food of narwhals and other arctic whales. Common names and taxonomy The common names "Arctic cod" and "polar cod" can refer to either ''Arctogadus glacialis'' or ''Boreogadus saida'', and "Arctic cod" may also refer to '' Eleginus nawaga''. Another Arctic gadid, the East Siberian cod (''Arctogadus borisovi''), was until recently considered the closest relative of ''A. glacialis''. It has, however, been found not to be distinct from ''A. glacialis'', and should be included in this species. According to this result, ''Arctogadus'' is a monotypic genus. However, ''Arctogadus'' is a close relative of '' Boreogadus'', and should perhaps be included in that genus. Appearance Arctic cod have been ...

Shore Lead
A shore lead (or coastal lead) is an oceanographic term for a waterway opening between pack ice and shore. While the gap of water may be as narrow as a tide crack if closed by wind or currents, it can be as wide as . Its formation can be influenced by tidal action, or subsurface conditions, such as current and ocean floor. Commonly, a shore lead is navigable by surface vessels. An opening ("lead") between pack ice and fast ice Fast ice (also called ''land-fast ice'', ''landfast ice'', and ''shore-fast ice'') is sea ice that is "fastened" to the coastline, to the sea floor along shoals or to grounded icebergs.Leppäranta, M. 2011.

Sea Ice
Sea ice arises as seawater freezes. Because ice is less dense than water, it floats on the ocean's surface (as does fresh water ice, which has an even lower density). Sea ice covers about 7% of the Earth's surface and about 12% of the world's oceans. Much of the world's sea ice is enclosed within the polar ice packs in the Earth's polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Polar packs undergo a significant yearly cycling in surface extent, a natural process upon which depends the Arctic ecology, including the ocean's ecosystems. Due to the action of winds, currents and temperature fluctuations, sea ice is very dynamic, leading to a wide variety of ice types and features. Sea ice may be contrasted with icebergs, which are chunks of ice shelves or glaciers that calve into the ocean. Depending on location, sea ice expanses may also incorporate icebergs. General features and dynamics Sea ice does not simply grow and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avro Lancaster
The Avro Lancaster is a British Second World War heavy bomber. It was designed and manufactured by Avro as a contemporary of the Handley Page Halifax, both bombers having been developed to the same specification, as well as the Short Stirling, all three aircraft being four-engined heavy bombers adopted by the Royal Air Force (RAF) during the same wartime era. The Lancaster has its origins in the twin-engine Avro Manchester which had been developed during the late 1930s in response to the Air Ministry Specification P.13/36 for a medium bomber for "world-wide use" which could carry a torpedo internally, and make shallow dive-bombing attacks. Originally developed as an evolution of the Manchester (which had proved troublesome in service and was retired in 1942), the Lancaster was designed by Roy Chadwick and powered by four Rolls-Royce Merlins and in one of the versions, Bristol Hercules engines. It first saw service with RAF Bomber Command in 1942 and as the strategic bom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Melville Island (Northwest Territories And Nunavut)
Melville IslandCoordinates are located on the NWT side. (french: Île Melville; Inuktitut: ''ᐃᓗᓪᓕᖅ, Ilulliq'') is an uninhabited island of the Arctic Archipelago with an area of . It is the 33rd largest island in the world and Canada's eighth largest island. Mountains on Melville Island, some of the largest in the western Canadian Arctic, reach heights of . There are two subnational pene-exclaves that lie west of the 110th meridian and form part of the Northwest Territories. These can only be reached by land from Nunavut or boat from the Northwest Territories. Melville Island is shared by the Northwest Territories, which is responsible for the western half of the island, and Nunavut, which is responsible for the eastern half. The border runs along the 110th meridian west. Geography The island has little or no vegetation. Where continuous vegetation occurs, it usually consists of hummocks of mosses, lichens, grasses, and sedges. The only woody s ...
