In fact, when using GPS right at the pole, the highest elevation GPS satellite you would see is about 45 degrees above the horizon. An example of a dwarf shrub is the bearberry. The reasons are mainly the satellite-receiver geometry and the ionospheric effects on the satellite signals, but also users do not have the benefits of satellite . Polar bears follow the sea ice habitat, and so their range has actually drifted south. //. The Arctic Circle passes through the Arctic Ocean, the Scandinavian Peninsula, North Asia, Northern America, and Greenland. While the cities below are quite cold, most still have a milder climate than anyplace north of the Arctic Circle in North America. [18] Supported by genetic testing, evidence shows that descendants of the Dorset culture, known as the Sadlermiut, survived in Aivilik, Southampton and Coats Islands, until the beginning of the 20th century.[19]. Potential methane release from the region, especially through the thawing of permafrost and methane clathrates, is also a concern. In the winter, machinery can freeze, and the frozen ground becomes too hard to drill. The Arctic Circle is roughly 16,000km (9,900mi) in circumference. More than half the population of Nunavut identifies as Inuit, and Inuktitut is the most-spoken language. The true Arctic is the area in which the mean temperature for the warmest month is less than 50 F (10 C). However, because of atmospheric refraction and mirages, and also because the sun appears as a disk and not a point, part of the midnight sun may be seen on the night of the northern summer solstice up to about 50 minutes () (90km (56mi)) south of the Arctic Circle; similarly, on the day of the northern winter solstice, part of the sun may be seen up to about 50 north of the Arctic Circle. Wiki User. Russia in search of its Arctic strategy: between hard and soft power? As one moves northward, the amount of warmth available for plant growth decreases considerably. The dark surface of the liquid ocean, however, absorbs about 90% of solar radiation. The surrounding six Arctic states that border the Arctic OceanCanada, Kingdom of Denmark (with Greenland), Iceland, Norway, Russia, and the United Statesare limited to a 200 nautical miles (370km; 230mi) exclusive economic zone (EEZ) off their coasts. Therefore, that information is unavailable for most Encyclopedia.com content. In fact, the Arctic is not even the coldest place in the Northern Hemisphere. The eight Arctic nations (Canada, Kingdom of Denmark [Greenland & The Faroe Islands], Finland, Iceland, Norway, Sweden, Russia, and USA) are all members of the Arctic Council, as are organizations representing six indigenous populations. Arctic Council Established by the Ottawa Declaration in 1996, the Arctic Council is the preeminent intergovernmental forum for addressing issues related to the Arctic Region. The Polar Silk Road. This fluctuation is present because of tidal forces resulting from the orbit of the moon. The flag-placing during Arktika 2007 generated commentary on and concern for a race for control of the Arctic's vast hydrocarbon resources. Coastal Arctic climates are moderated by oceanic influences, having generally warmer temperatures and heavier snowfalls than the colder and drier interior areas. Population: 28,639 inhabitants. The Barents Region consists of northernmost parts of Norway, Sweden, Finland and North-West Russia. In August 2015, Russia made a supplementary submission for the expansion of the external borders of its continental shelf in the Arctic Ocean, asserting that the eastern part of the Lomonosov Ridge and the Mendeleyev Ridge are an extension of the Eurasian continent.

In 2016, a luxury cruise ship traveled through the Northwest Passage for the first time.

In spite of its name, permafrost is not always permanent. High winds often stir up snow, creating the illusion of continuous snowfall. . In Alaska, many oil companies work with indigenous groups known as native corporations to drill and export millions of barrels of oil every year. [24][25], Research in the Arctic has long been a collaborative international effort, evidenced by the International Polar Year. It is also the least salty, due to low evaporation and huge influxes of freshwater from rivers and glaciers. Some of these mineral deposits are underground, while others are buried beneath the Arctic Ocean. The largest such community in Canada is Iqaluit in Nunavut, with about 8,000 people living there. North Pacific Ocean - Bathymetry, currents, Islands. Race for the ArcticAlmost all Arctic nations are scrambling to assert authority over the rich resources of the Arctic. ." The Arctic is a region of the planet, north of the Arctic Circle, and includes the Arctic Ocean, Greenland, Baffin Island, other smaller northern islands, and the far northern parts of Europe, Russia (Siberia), Alaska and Canada. Russia manufactures the most powerful icebreakers. [5] The name refers either to the constellation Ursa Major, the "Great Bear", which is prominent in the northern portion of the celestial sphere, or to the constellation Ursa Minor, the "Little Bear", which contains the celestial north pole (currently very near Polaris, the current north Pole Star, or North Star). However, the date of retrieval is often important. The Arctic ice cap helps to regulate Earth's temperature by reflecting sunlight. . Russian explorers navigated the Northern Sea Route of the Northeast Passage and the Siberian Arctic, eventually crossing the Bering Strait in the 1600s. The increasingly shrinking Arctic sea ice provides clear shipping routes for trade and travel. The Arctic Circle, incidentally, is an imaginary line located at 66, 30'N latitude, and as a guide defines the southernmost part of the Arctic. Earth's arctic and subarctic regions are extremely cold, icy areas of land and sea that receive almost no sunlight during their long, dark winters. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list. It is the farthest region that experience polar days and polar nights. Administrative Areas. Yenikeyeff, S. M. and Fenton Krysiek, Timothy (August 2007). Everything north of this circle is known as the Arctic and the zone just to the south of this circle is the Northern . The International Arctic Science Committee, hundreds of scientists and specialists of the Arctic Council, and the Barents Euro-Arctic Council are more examples of collaborative international Arctic research.[26]. 1996 - 2022 National Geographic Society. Maps of the Arctic Region. Because of the amplified response of the Arctic to global warming, it is often seen as a leading indicator of global warming. A ring of continental land masses and large islands surrounds the ice-covered Arctic Ocean over the North Pole. The Arctic also holds 1/5 of the Earth's water supply.[14]. U*X*L Encyclopedia of Water Science. The North Pole lies under a zone of dry, sinking air in the atmosphere (mass of air surrounding Earth), and the Arctic and is a windblown, frozen desert that receives very little snow each year (it almost never rains there because it is too cold). In the mid winter months, the sun never rises and temperatures can easily reach lows of - 50 F in the higher latitudes. Antarctic Latitudes. The polar bear is also a predator, though it prefers to hunt for marine life from the ice. In the interior, summers can be quite warm, while winters are extremely cold. Resources in the Arctic The Arctic has enormous deposits of oil and natural gas. Without sea ice, polar bears cannot catch enough seals to survive their annual winter fast.

This page was last edited on 25 October 2022, at 18:07. Several hypotheses for how Arctic warming may be influencing mid-latitude weather patterns have been proposed recently. The permanent covering of ice over its large area is called the Arctic ice cap. The indigenous Eskimos have lived in the area for over 9,000 years, and many have now given up much of their traditional hunting and fishing to work in the oil fields and the varied support villages. The Arctic contains some of the last and most extensive continuous wilderness areas in the world, and its significance in preserving biodiversity and genotypes is considerable.
