When the AO is strongly negative, a . [10] The area north of the Circle is about 20,000,000km2 (7,700,000sqmi) and covers roughly 4% of Earth's surface.[11]. Eskimo tribes of Siberia, Arctic North America, and Greenland live in snow shelters, hunt the tundra, and use boats called kayaks to fish the icy Arctic waters. (Some icebergs, including the infamous 1912 sinker of the cruise ship Titanic, float south into "iceberg alley" in the North Atlantic Ocean where they are a hazard to shipping.) Kirovsk, Russia. Russian explorers navigated the Northern Sea Route of the Northeast Passage and the Siberian Arctic, eventually crossing the Bering Strait in the 1600s. Distribute the student worksheet The Arctic Region. 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. . Inuit communities also built tents with poles crafted from driftwood and whale bones or baleen. The increasingly shrinking Arctic sea ice provides clear shipping routes for trade and travel. Konyshev, Valery & Sergunin, Alexander: Is Russia a revisionist military power in the Arctic? The Arctic at the crossroads of geopolitical interests // Russian Politics and Law, 2012. The arctic region sits inside the Arctic Circle and the subarctic region lies just below it. [6] The differential warming of the Arctic relative to mid-latitudes is the key linking AA with patterns favoring persistent weather conditions in mid-latitudes. Definitions of the Arctic. Konyshev, Valery & Sergunin, Alexander. Since ice can appear on or in the earth as well as in its seas and other bodies of water and, An iceberg is a large mass of free-floating ice that has broken away from a glacier. IcebreakersTravel in the Arctic is still dependent on icebreakers. . Primary consumers across the region range from tiny lemmings to enormous muskoxen. In spite of its name, permafrost is not always permanent. Like the polar bear, many other animals of the Arctic are white: beluga whales, snowy owls, juvenile harp seals. This frozen seawater is called sea ice. [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). Birds and mammals travel north to join those that stayed for the winter. [16][17] The Dorset culture (Inuktitut: Tuniit or Tunit) refers to the next inhabitants of central and eastern Arctic. Permafrost is a problem for the engineers who build roads, buildings, and pipelines in the tundra. High winds often stir up snow, creating the illusion of continuous snowfall. The climate north of the Arctic Circle is generally cold, but the coastal areas of Norway have a generally mild climate as a result of the Gulf Stream, which makes the ports of northern Norway and northwest Russia ice-free all year long. The initial focus of the campaign will be a UN resolution creating a global sanctuary around the pole, and a ban on oil drilling and unsustainable fishing in the Arctic. Without sea ice, polar bears cannot catch enough seals to survive their annual winter fast. Some geologists estimate that there may be between 5 billion and 16 billion barrels of oil and natural gas beneath the coastal plain of the refuge. Arctic Circle Latitude. Not to be confused with it's colder, Southern Hemisphere counterpart known as the Antarctic Circle, the Arctic Circle is located approximately 66.5 degrees north of the equator (the exact. Arctic life is characterized by adaptation to short growing seasons with long periods of sunlight, and cold, dark, snow-covered winter conditions. The position of the Arctic Circle is not fixed and currently runs 663349.1 north of the Equator. Organic nutrients are thus recycled into the marine ecosystem of the Arctic. Animals such as the Chasmosaurus, Hypacrosaurus, Troodon, and Edmontosaurus may have all migrated north to take advantage of the summer growing season, and migrated south to warmer climes when winter came. 2012-10-09 04:04:32. If no button appears, you cannot download or save the media. During the Cretaceous time period, the Arctic still had seasonal snows, though only a light dusting and not enough to permanently hinder plant growth. A Naturalist's Guide to the Arctic.

What countries are in the Arctic region and where is the Arctic North [11] Perhaps the most alarming result of this is Arctic sea ice shrinkage. approximately 66.5 degrees north The Arctic Circle is a parallel of latitude on the Earth at approximately 66.5 degrees north from the equator. The Northwest Passage was not completely navigated until 1906, when legendary Norwegian explorer Roald Amundsen and his crew made the voyage from Greenland to Alaska. (Glaciers are flowing masses of ice, created by years of snowfal, Ice is the solid state of water . The Arctic circle, meanwhile, begins at about 66.5 degrees north. [34], Canada claims the Northwest Passage as part of its internal waters belonging to Canada, while the United States and most maritime nations[35] regards it as an international strait, which means that foreign vessels have right of transit passage. Starting in the late 20th century, regional, national, and international organizations increasingly recognized the political and cultural sovereignty of Arctic peoples. National Snow and Ice Data Center.http://nsidc.org/sotc (accessed on August 17, 2004). The fascination of the high latitudes. //]]>. Map of Bioclimatic Subzones & Boreal Forests. Russia manufactures the most powerful icebreakers. Wiki User. Currents carry sea ice south, however, as it breaks up. Population: 28,639 inhabitants. 16 answers. While each of these Arctic regions have their own distinct charms, the Arctic as a whole offers adventurers a unique polar experience. The climates of polar lands vary greatly depending on their latitude, proximity of the sea, elevation, and topography, but, even so, they all share certain "polar" characteristics.Owing to the high latitudes, solar energy is limited to the summer months. Rights to land and natural resources are an important part of this sovereignty. Natural resource exploration and extraction initiatives also have an increased presence and impact within the region. The Sun's rays hit the poles at a very shallow angle and the summer sunlightwhile long-lastingis too weak to provide much heat. Logic might indicate that polar bears would migrate further north as their traditional range heats up. One of the most familiar Arctic herbivores is the caribou, often known as the reindeer in Europe and Asia. The first explorers of the Arctic were Vikings. In 2016, a luxury cruise ship traveled through the Northwest Passage for the first time. She or he will best know the preferred format. Large islands extend even farther north: Nova Zemlya (Russia), Spitsbergen (Norway), Iceland, Greenland (Denmark), and the Queen Elizabeth Islands (Canada). International Code for Ships Operating in Polar Waters, United Nations Convention on the Law of the Sea, Learn how and when to remove this template message, "The American Heritage Dictionary entry: arctic", "Organisms that thrive in Arctic sea ice. The general hypothesis is that when the Arctic warms faster than lower latitude regions, the north-south temperature difference is reduced. Most of the roughly four million inhabitants live on lands bordering the Arctic Ocean. Challenges of Indigenous CulturesRights to land and natural resources are an important part of contemporary culture and survival of indigenous peoples in the Arctic. The historically nomadic Sami (an indigenous people of Scandinavia and northwestern Russia) also built temporary tent-like structures, called lavvu. Primary consumers such as jellies and shrimp consume plankton, the basis of the Arctic marine food web. The position of the Arctic Circle is not fixed and currently runs 663349.2 north of the Equator. . 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, Siberia, Nenets Okrug, Novaya Zemlya), Sweden and the United States (Alaska). On 2 August 2007, two Russian bathyscaphes, MIR-1 and MIR-2, for the first time in history descended to the Arctic seabed beneath the North Pole and placed there a Russian flag made of rust-proof titanium alloy. There are hardly any other natural landscapes that fascinate mankind as much as the distant land and marine regions of the Arctic and Antarctic. Russia's Arctic ambitions have attracted increasing attention in the West over the past decade as climate change opens up new opportunities in the region for navigation and exploration of its riches. [4] Its latitude depends on the Earth's axial tilt, which fluctuates within a margin of more than 2 over a 41,000-year period, owing to tidal forces resulting from the orbit of the Moon. Resources in the Arctic The Arctic has enormous deposits of oil and natural gas. Riddle of the Ice: A Scientific Adventure into theArctic. The Arctic is one of Alaska's most remote and diverse regions, filled with cultural opportunities, unique wildlife, and a landscape ranging from the Arctic coastline to broad stretches of tundra to the dramatic peaks of the Brooks Range.Vast areas of the Arctic are protected as national parks and wildlife refuges, including Gates of the Arctic National Park and Preserve and Arctic National . Encyclopedia.com. issued an 1800 page report on climate changes in circumpolar regions, representing four years . In spite of its harsh climate, the subarctic tundra supports a wide range of biological species. Due to the prevailing worldwide sea and air currents, the Arctic area is the fallout region for long-range transport pollutants, and in some places the concentrations exceed the levels of densely populated urban areas. Loss of sea ice and warmer temperatures north of central Asia increase the intensity of the Siberian high pressure system. [10], Due to the poleward migration of the planet's isotherms (about 56km (35mi) per decade during the past 30 years as a consequence of global warming), the Arctic region (as defined by tree line and temperature) is currently shrinking. Arctic Seaways . However, the date of retrieval is often important. The word Arctic comes from the Greek word (arktikos), "near the Bear, northern"[4] and from the word (arktos), meaning bear. The Lomonosov Ridge is an undersea mountain chain that stretches from the Canadian Arctic, through the North Pole, all the way to the waters off Siberia.

Other Circumpolar North indigenous peoples include the Chukchi, Evenks, Iupiat, Khanty, Koryaks, Nenets, Sami, Yukaghir, Gwich'in, and Yupik. ARCTIC. Each summer, water in the upper few feet of arctic and subarctic permafrost melts for a few months. Upon ratification of the United Nations Convention on the Law of the Sea, a country has ten years to make claims to an extended continental shelf beyond its 200 nautical mile zone. Temperatures rarely rise above freezing. Encyclopedia.com. The Arctic is the northernmost region of Earth. [44][45] Release of methane and carbon dioxide stored in permafrost could cause abrupt and severe global warming,[46] as they are potent greenhouse gases. (October 27, 2022). The Arctic Ocean is a hub of globally significant, intersecting economic and environmental activity and interest. False. Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. "[22][32], As of 2012, the Kingdom of Denmark is claiming the continental shelf based on the Lomonosov Ridge between Greenland and over the North Pole to the northern limit of the Russian EEZ. This is true even during summer in the "land of the midnight sun." 10. The members of the Arctic Council include the eight Arctic States (Canada, Denmark, Finland, Iceland, Norway, Sweden, the Russian Federation, and the United States). This albedo means about 80% of sunlight that strikes sea ice is reflected back to space.

[9] The melting of Greenland's ice sheet is linked to polar amplification. image of Eskimos as fur-clad hunters that live in igloos instead of a diverse group of loosely-related arctic cultures that have their far-northern latitude in common. Housing or other shelter, for example, poses unusual challenges for Arctic peoples. Most of the Arctic, however, is the liquid saltwater of the Arctic ocean basin. [47], Climate change is also predicted to have a large impact on tundra vegetation, causing an increase of shrubs,[48] and having a negative impact on bryophytes and lichens. Directly on the Arctic Circle these events occur, in principle, exactly once per year: at the June and December solstices, respectively. The climate within the Circle is very cold and much of the area is always covered with ice. The 12- or 13-day Antarctic Latitudes voyage sails round-trip from Ushuaia. The polar bear, the iconic apex predator of the Arctic, is equally able to hunt on land and around ice floes. The Arctic region is a unique area among Earth's ecosystems. In August 2016, the UN Commission on the Limits of the Continental Shelf began to consider Russia's submission. Antarctic Latitudes. Oil in ANWRThe Arctic National Wildlife Refuge (ANWR), situated on Alaskas northeastern coast, is the largest protected wilderness in the United States. 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. The Arctic is warming much faster than the rest of the planet, a phenomenon called Arctic amplification. Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. It marks the southernmost latitude where the sun can stay continuously below . Much of the land in the Arctic Circle is tundra: a harsh, treeless environment with permanently frozen . There is no single correct definition of the region as the southern boundary varies. The Arctic is particularly susceptible to the abrasion of groundcover and to the disturbance of the rare breeding grounds of the animals that are characteristic to the region. Arctic humans, like polar bears, survive the winter by insulating themselves. The Arctic includes the peaks of the Brooks mountain range in western North America, the enormous Greenland ice sheet, the isolated islands of the Svalbard archipelago, the fjords of northern Scandinavia, and the grassland plateaus and rich river valleys of northern Siberia. Actually, the Arctic Circle does not enclose all the Arctic regions. Its southern equivalent is the Antarctic Circle. The Rights Holder for media is the person or group credited. The Polar Regions are defined by the Antarctic and Arctic Circles. The Arctic Circle is a line of latitude that circles the globe at approximately 6633 North of the equator. Glaciology is the study of ice and its effects. They have all developed smart, innovative ways to adapt to the unique challenges posed by the regions severe climate. Latitude: 6732'N. Kirovsk is a town in Murmansk Oblast, Russia, located at the spurs of the Khibiny Massif on the shores of the . DOI: 10.1017/CBO9781107337442. Birds nest on the tundra. Even fluffy white baby seals will ultimately grow up to a dark brownbetter to blend in with the dark Arctic ocean waters instead of blinding white ice floes. "State of the Cryosphere." An icebreaker is a very powerful ship capable of breaking up kilometers of sea ice, sometimes several meters thick. Arctic Circle Map The Arctic Circle is the imaginary line located at 66, 30'N latitude and marks the southernmost boundary of the Arctic region. The Dorset culture evolved because of technological and economic changes during the period of 1050550 BCE. The rectangular blocks were stacked in tight spiral pattern, giving the igloo a domed shape. Many people think that the Arctic Region is only Nunavut, the Yukon and Northwest Territories when really, the Arctic is everything that is north of the 60 N parallel (latitude) . For hundreds of years, for instance, European and Asian explorers interacted with Inuit communities in the Canadian Arctic, searching for the North Pole and the elusive Northwest Passage. (The Northwest Passage is a sea route connecting the North Pacific and North Atlantic ocean basins.) Often, sea ice is covered with a thick blanket of snow. The dark surface of the liquid ocean, however, absorbs about 90% of solar radiation. There are no permanent settlements above 78 north latitude. The Arctic Circle marks the southernmost latitude at which, on the December solstice, the shortest day of the year in the northern hemisphere, the sun will not rise all day, and on the June solstice, the longest day of the year in the northern hemisphere, the sun will not set. "The Tundra." Life in the ArcticMarine EcosystemThe Arctic ocean basin is the shallowest of the five ocean basins on Earth. His study explains in a straightforward language the rules governing the division and protection of the Arctic and the disputes that remain unsolved. Areas north of this line experience the polar night (a period of 24 sunless hours) and the polar day (a period of 24 sunlight hours) at least once per year. Because that temperature difference provides the main fuel for the polar jet stream (a river of strong wind at levels where jet aircraft fly), the predominantly west winds of the jet stream weaken. (The icy, subarctic interior of Siberia, in eastern Russia, holds that record.). [49], Apart from concerns regarding the detrimental effects of warming in the Arctic, some potential opportunities have gained attention. Byers is a known expert on the Arctic region. [50] One harbinger of the opening navigability of the Arctic took place in the summer of 2016 when the Crystal Serenity successfully navigated the Northwest Passage, a first for a large cruise ship.
