Broughton Island (Nunavut)
Broughton Island is a island in the Arctic Archipelago. Geography It is located above the Arctic Circle in the Davis Strait, off Baffin Island about west of the Cumberland Peninsula. To the east Baffin Bay, and the Baffin Mountains are located to the west, more specifically the Arctic Cordillera mountain range. Demographics The only community on the island is Qikiqtarjuaq with a population of 593. It is one of only eleven islands, out of more than 36,000, in the Arctic Archipelago that are inhabited. The Inuit residents of Qikiqtarjuaq moved there in 1963 from a whaling station at Kivitoo about north. Qikiqtarjuaq hosts an annual "Suicide Prevention Walk". Local participants would walk a total distance of across the tundra from Kivitoo' Today the walk is much shorter than the original two and a half days, but it is still meant to promote hope among the community. The island was the home of FOX-5, a Distant Early Warning Line and now a North Warning System site. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cumberland Peninsula
Cumberland Peninsula is a peninsula in the southeastern part of Baffin Island in Nunavut, Canada. It is located between 64°56' and 67°57' north latitude, and 61°56' to 68° west longitude. The Arctic Circle crosses the peninsula, with the Labrador Sea to the southeast, and the Davis Strait to the east, which lies between the peninsula and Greenland. The Cumberland Sound lies to the southwest, separating the Cumberland Peninsula from the Hall Peninsula, which is also part of Baffin Island. The Cumberland Peninsula is part of the Arctic Tundra biome—the world's coldest and driest biome—as is the rest of Baffin Island. The terrain is mountainous, and Mt. Odin, near the Arctic Circle, rises . The peninsula is home to Pangnirtung, which lies on the southwest coast, and the Auyuittuq National Park. References Further reading * Dyke, Arthur S., John T.

North Warning System
The North Warning System (NWS) is a joint United States and Canadian early-warning radar system for the atmospheric air defense of North America. It provides surveillance of airspace from potential incursions or attacks from across North America's polar region. It replaced the Distant Early Warning Line system in the late 1980s. Overview The NWS consists of both long range AN/FPS-117 and short range AN/FPS-124 surveillance radars, operated and maintained by North American Aerospace Defense Command (NORAD). There are 13 long range sites and 36 short range sites. In Canada, the station sites are owned or leased by the Government of Canada, which also owns most of the infrastructure. The radars and tactical radios are owned by the United States Air Force. The Alaska Regional Operations Control Center (ROCC) at Elmendorf AFB, Alaska controls the stations in Alaska; the Canada East and Canada West Regional Operations Control Centres (ROCCs) at CFB North Bay, Ontario control the ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tundra Climate
The tundra climate is a polar climate sub-type located in high latitudes and high mountains. undra climate https://www.britannica.com/science/tundra-climateThe Editors of Encyclopaedia Britannica, 2019 It is classified as ET according to Köppen climate classification. It is a climate which at least one month has an average temperature high enough to melt snow (), but no month with an average temperature in excess of . Despite the potential diversity of climates in the ''ET'' category involving precipitation, extreme temperatures, and relative wet and dry seasons, this category is rarely subdivided. Rainfall and snowfall are generally slight due to the low vapor pressure of water in the chilly atmosphere, but as a rule potential evapotranspiration is extremely low, allowing soggy terrain of swamps and bogs even in places that get precipitation typical of deserts of lower and middle latitudes. The amount of native tundra biomass depends more on the local temperature than the amoun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Auyuittuq National Park
Auyuittuq National Park ( iu, ᐊᐅᔪᐃᑦᑐᖅ, , "the land that never melts") is a national park located on Baffin Island's Cumberland Peninsula, in the Qikiqtaaluk Region of Nunavut, the largest political subdivision of Canada. The park was initially known as ''Baffin Island National Park'' when it was established in 1972, but the name was changed in 1976 to its current name to better reflect the region and its history. It features many terrains of Arctic wilderness, such as fjords, glaciers, and ice fields. Although Auyuittuq was established in 1972 as a national park reserve, it was upgraded to a full national park in 2000.

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 ...

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 ...

Polar Bear
The polar bear (''Ursus maritimus'') is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the largest extant bear species, as well as the largest extant land carnivore. A boar (adult male) weighs around , while a sow (adult female) is about half that size. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means "maritime bear" and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar be ...

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 ...

Arctic
The Arctic ( or ) is a polar regions of Earth, polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), Finland, Iceland, Norway, Russia (Murmansk Oblast, Murmansk, Siberia, Nenets Autonomous Okrug, Nenets Okrug, Novaya Zemlya), Sweden and the United States (Alaska). Land within the Arctic region has seasonally varying snow and sea ice, ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. De ...
