Isachsen, Nunavut
Isachsen is a remote Arctic research-weather station named after the Norwegian explorer of the Arctic, Gunnar Isachsen. It is on the western shore of Ellef Ringnes Island in the Sverdrup Islands, in the territory of Nunavut in Canada. Isachsen Station was established to participate in a joint Canadian-American weather observation program. Isachsen Station operated from April 3, 1948, through September 19, 1978. Regular weather observations began on May 3, 1948. In October 1949, a Douglas C-47 Skytrain (tail number 316062) crash-landed near the station. No one was killed, but three on board were injured. The wreckage has been preserved by the cold weather and dry conditions. Climate According to Environment and Climate Change Canada, Isachsen and the surrounding area has the worst weather in Canada with a Climate Severity Index of 99 out of a possible 100. The climate of Isachsen is a severe tundra climate, with short, cool summers and long, cold winters. The record high is on ...

Provinces And Territories Of Canada
Within the geographical areas of Canada, the ten provinces and three territories are sub-national administrative divisions under the jurisdiction of the Canadian Constitution. In the 1867 Canadian Confederation, three provinces of British North America—New Brunswick, Nova Scotia, and the Province of Canada (which upon Confederation was divided into Ontario and Quebec)—united to form a federation, becoming a fully independent country over the next century. Over its history, Canada's international borders have changed several times as it has added territories and provinces, making it the world's second-largest country by area. The major difference between a Canadian province and a territory is that provinces receive their power and authority from the ''Constitution Act, 1867'' (formerly called the ''British North America Act, 1867''), whereas territorial governments are creatures of statute with powers delegated to them by the Parliament of Canada. The powers flowing from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Fox
The Arctic fox (''Vulpes lagopus''), also known as the white fox, polar fox, or snow fox, is a small fox native to the Arctic regions of the Northern Hemisphere and common throughout the Arctic tundra biome. It is well adapted to living in cold environments, and is best known for its thick, warm fur that is also used as camouflage. It has a large and very fluffy tail. In the wild, most individuals do not live past their first year but some exceptional ones survive up to 11 years. Its body length ranges from , with a generally rounded body shape to minimize the escape of body heat. The Arctic fox preys on many small creatures such as lemmings, voles, ringed seal pups, fish, waterfowl, and seabirds. It also eats carrion, berries, seaweed, and insects and other small invertebrates. Arctic foxes form monogamous pairs during the breeding season and they stay together to raise their young in complex underground dens. Occasionally, other family members may assist in raising their y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prince Patrick Island
A member of the Arctic Archipelago, Prince Patrick Island is the westernmost of the Queen Elizabeth Islands in the Northwest Territories of Canada, lying northwest of Melville Island. The area of Prince Patrick Island is , making it the 55th largest island in the world and Canada's 14th largest island. It has historically been icebound all year, making it one of the least accessible parts of Canada. Located at the entrance of the M'Clure Strait, Prince Patrick Island is uninhabited. The first known sighting of the island was in 1853 by the Irish naval officer George Mecham, when it was explored by him and his fellow Irish explorer Francis Leopold McClintock in the spring of that year during the Edward Belcher expedition. Much later, it was named for Prince Arthur William Patrick, Duke of Connaught, who was Governor General of Canada from 1911 to 1916. The island rises to only about , and the area is seismically active. Weather Station A High Arctic Weather Station ("HA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiosonde
A radiosonde is a battery-powered telemetry instrument carried into the atmosphere usually by a weather balloon that measures various atmospheric parameters and transmits them by radio to a ground receiver. Modern radiosondes measure or calculate the following variables: altitude, pressure, temperature, relative humidity, wind (both wind speed and wind direction), cosmic ray readings at high altitude and geographical position (latitude/longitude). Radiosondes measuring ozone concentration are known as ozonesondes. Radiosondes may operate at a radio frequency of 403 MHz or 1680 MHz. A radiosonde whose position is tracked as it ascends to give wind speed and direction information is called a rawinsonde ("radar wind -sonde"). Most radiosondes have radar reflectors and are technically rawinsondes. A radiosonde that is dropped from an airplane and falls, rather than being carried by a balloon is called a dropsonde. Radiosondes are an essential source of meteorological data ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Magnetic Pole
The north magnetic pole, also known as the magnetic north pole, is a point on the surface of Earth's Northern Hemisphere at which the Earth's magnetic field, planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down). There is only one location where this occurs, near (but distinct from) the geographic north pole. The Geomagnetic pole, geomagnetic north pole is the northern Antipodes, antipodal pole of an ideal dipole model of the Earth's magnetic field, which is the most closely fitting model of Earth's actual magnetic field. The north magnetic pole moves over time according to magnetic changes and flux lobe Elongation (materials science), elongation in the Earth's outer core. In 2001, it was determined by the Geological Survey of Canada to lie west of Ellesmere Island in northern Canada at . It was situated at in 2005. In 2009, while still situated within the Canadian ...

Top Gear (2002 TV Series)
''Top Gear'' is a British motoring magazine and factual television programme, designed as a relaunched version of the Top Gear (1977 TV series), original 1977 show of the same name by Jeremy Clarkson and Andy Wilman for the BBC, and premiered on 20 October 2002. The programme focuses on the examination and reviewing of motor vehicles, primarily cars, though this was expanded upon after the broadcast of its earlier series to incorporate films featuring motoring-based challenges, special races, timed laps of notable cars, and celebrity timed laps on a course specially-designed for the relaunched programme. The programme drew acclaim for its visual and presentation style since its launch, which focused on being generally entertaining to viewers, as well as Top Gear controversies, criticism over the controversial nature of its content. The show was also praised for its occasionally-controversial humor and lore existing in not just the automotive community but in the form of internet ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muskox
The muskox (''Ovibos moschatus'', in Latin "musky sheep-ox"), also spelled musk ox and musk-ox, plural muskoxen or musk oxen (in iu, ᐅᒥᖕᒪᒃ, umingmak; in Woods Cree: ), is a hoofed mammal of the family Bovidae. Native to the Arctic, it is noted for its thick coat and for the strong odor emitted by males during the seasonal rut, from which its name derives. This musky odor has the effect of attracting females during mating season. Its Inuktitut name "umingmak" translates to "the bearded one". Its Woods Cree names "mâthi-môs" and "mâthi-mostos" translate to "ugly moose" and "ugly bison", respectively. Muskoxen primarily live in Greenland and the Canadian Arctic of the Northwest Territories and Nunavut, with reintroduced populations in the American state of Alaska, the Canadian territory of Yukon, and Siberia, and an introduced population in Norway, part of which emigrated to Sweden, where a small population now lives.

Pinniped
Pinnipeds (pronounced ), commonly known as seals, are a widely distributed and diverse clade of carnivorous, fin-footed, semiaquatic, mostly marine mammals. They comprise the extant families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals). There are 34 extant species of pinnipeds, and more than 50 extinct species have been described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular evidence supports them as a monophyletic lineage (descended from one ancestral line). Pinnipeds belong to the order Carnivora; their closest living relatives are musteloids (weasels, raccoons, skunks, and red pandas), having diverged about 50 million years ago. Seals range in size from the and Baikal seal to the and southern elephant seal male, which is also the largest member of the order Carnivora. Several species exh ...
