Named after the Arctic exploration vessel HMS Resolute , it is located in Parry Channel on the southern side of Cornwallis Island . The hamlet of Resolute is located on the northern shore of the bay with Resolute Bay Airport to the northwest. The Inuit associated with Resolute Bay are called Qausuittuq and

The flag-placing, during Arktika 2007 , generated commentary on and concern for a race for control of the Arctic's vast hydrocarbon resources.

There are copious natural resources in the Arctic (oil, gas, minerals, fresh water, fish and, if the subarctic is included, forest) to which modern technology and the economic opening up of Russia have given significant new opportunities. The interest of the tourism industry is also on

The area can be defined as north of the Arctic Circle (about 66° 34'N), the approximate southern limit of the midnight sun and the polar night . Another definition of the Arctic, which is popular with ecologists , is the region in the Northern Hemisphere where the average temperature for the warmest month (July) is below 10 °C (50 °F);

The Arctic region, from the IERS Reference Meridian travelling east, consists of parts of northern Norway ( Nordland , Troms , Finnmark , Svalbard and Jan Mayen ), northernmost Sweden ( Västerbotten , Norrbotten and Lappland ), northern Finland ( North Ostrobothnia , Kainuu and Lappi ), Russia ( Murmansk , Siberia , Nenets Okrug , Novaya Zemlya ),

Arctic life is characterized by adaptation to short growing seasons with long periods of sunlight, and cold, dark, snow-covered winter conditions. Arctic vegetation is composed of plants such as dwarf shrubs , graminoids , herbs , lichens , and mosses , which all grow relatively close to

The word Arctic comes from the Greek word ἀρκτικός ( arktikos ), "near

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 August 2016,
459-432: Is also a concern. Because of the amplified response of the Arctic to global warming, it is often seen as a leading indicator of global warming. The melting of Greenland's ice sheet is linked to polar amplification. The Arctic region is especially vulnerable to the effects of any climate change , as has become apparent with the reduction of sea ice in recent years. Climate models predict much greater climate change in

Apart from concerns regarding the detrimental effects of warming in the Arctic, some potential opportunities have gained attention. The melting of the ice is making the Northwest Passage , shipping routes through the northernmost latitudes, more navigable, raising

However, others claim that dinosaurs lived year-round at very high latitudes, such as near the Colville River , which is now at about 70° N but at the time (70 million years ago) was 10° further north. The earliest inhabitants of North America's central and eastern Arctic are referred to as the Arctic small tool tradition (AST) and existed c. 2500 BCE . AST consisted of several Paleo-Eskimo cultures, including

While there are several ongoing territorial claims in the Arctic , no country owns the geographic North Pole or the region of the Arctic Ocean surrounding it.

They are preyed on by the snowy owl , Arctic fox , grizzly bear , and Arctic wolf . The polar bear is also a predator, though it prefers to hunt for marine life from the ice. There are also many birds and marine species endemic to the colder regions. Other terrestrial animals include wolverines , moose , Dall sheep , ermines , and Arctic ground squirrels . Marine mammals include seals , walruses , and several species of cetacean — baleen whales and also narwhals , orcas , and belugas . An excellent and famous example of

The Dorset culture evolved because of technological and economic changes during the period of 1050–550 BCE. With the exception of the Quebec / Labrador peninsula, the Dorset culture vanished around 1500 CE. Supported by genetic testing , evidence shows that descendants of

These phenomena are referred to as polar night and midnight sun respectively, and the further north one progresses, the more pronounced these effects become. For example, in the Russian port city of Murmansk , three degrees above
1071-852: The UN Commission on the Limits of the Continental Shelf began to consider Russia's submission. Canada claims the Northwest Passage as part of its internal waters belonging to Canada, while the United States and most maritime nations regards it as an international strait , which means that foreign vessels have right of transit passage. Since 1937, the larger portion of the Asian-side Arctic region has been extensively explored by Soviet and Russian crewed drifting ice stations .

The Arctic is comparatively clean, although there are certain ecologically difficult localized pollution problems that present a serious threat to people's health living around these pollution sources.

Due to the poleward migration of the planet's isotherms (about 56 km (35 mi) 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. Perhaps the most alarming result of this is Arctic sea ice shrinkage. There

In particular, there are concerns that Arctic shrinkage, a consequence of melting glaciers and other ice in Greenland, could soon contribute to a substantial rise in sea levels worldwide. The current Arctic warming is leading to ancient carbon being released from thawing permafrost , leading to methane and carbon dioxide production by micro-organisms. Release of methane and carbon dioxide stored in permafrost could cause abrupt and severe global warming, as they are potent greenhouse gases . Climate change
1326-459: The Arctic Circle is currently drifting northwards at a speed of about 14.5 m (48 ft) per year. The word arctic comes from the Greek word ἀρκτικός ( arktikos : "near the Bear , northern") and that from the word ἄρκτος ( arktos : " bear "). The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the centre of the Sun can remain continuously above or below
1377-526: 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. In the interior, summers can be quite warm, while winters are extremely cold. For example, summer temperatures in Norilsk , Russia will sometimes reach as high as 30 °C (86 °F), while

The Dorset / Thule culture transition dates around the ninth–10th centuries CE. Scientists theorize that there may have been cross-contact of the two cultures with sharing of technology, such as fashioning harpoon heads, or the Thule may have found Dorset remnants and adapted their ways with

By 1300 CE, the Inuit , present-day Arctic inhabitants and descendants of Thule culture, had settled in west Greenland, and moved into east Greenland over the following century ( Inughuit , Kalaallit and Tunumiit are modern Greenlandic Inuit groups descended from Thule). Over time, the Inuit have migrated throughout the Arctic regions of Eastern Russia,

Its precipitation mostly comes in the form of snow and is low, with most of the area receiving less than 50 cm (20 in). High winds often stir up snow, creating the illusion of continuous snowfall.

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. In addition, it is believed that the Arctic seabed may contain substantial oil fields which may become accessible if the ice covering them melts. These factors have led to recent international debates as to which nations can claim sovereignty or ownership over

The evidence suggested that Inuit descend from the Birnirk of Siberia, who through the Thule culture expanded into northern Canada and Greenland, where they genetically and culturally completely replaced the Indigenous Dorset people some time after 1300 CE. The question of why the Dorset disappeared so completely has led some to suggest that Thule invaders wiped out

During the Cretaceous time period , the Arctic still had seasonal snows, though only a light dusting and not enough to permanently hinder plant growth. 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. A similar situation may also have been found amongst dinosaurs that lived in Antarctic regions, such as
