The
Arctic is the area around the
Earth's
North Pole. The Arctic includes parts of
Russia,
Alaska (
United States),
Canada,
Greenland (a territory of
Denmark),
Iceland,
Norway,
Sweden and
Finland, as well as the
Arctic Ocean.
There are numerous definitions of the Arctic region. The boundary is generally considered to be north of the
Arctic Circle (66° 33'N), which is the limit of the
midnight sun and the
polar night. Other definitions are based on climate and ecology, such as the 10°C (50°F) July
isotherm, which also roughly corresponds to the
tree line in most of the Arctic. Socially and politically, the Arctic region includes the northern territories of the eight Arctic states, including
Lapland, although by natural science definitions much of this territory is considered
subarctic.
The Arctic is mostly a vast,
ice-covered ocean, surrounded by treeless, frozen ground. It teems with life, including organisms living in the ice, fish and marine mammals, birds, land animals and human societies.
The Arctic region is, by its nature, a unique area. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. From the perspective of the physical, chemical and biological balance in the world, the Arctic region is in a key position. It reacts sensitively particularly to changes in the climate, which reflect extensively back on the global state of the environment. From the perspective of research into climatic change, the Arctic region is considered an early warning system.
The Arctic is also known as the
Land of the Midnight Sun as it is within the
Arctic Circle. The name
Arctic comes from the ancient
Greek αρκτος, meaning 'bear', and is a reference to the
constellations of the
Great Bear and
Little Bear, which are located near the
North Star (which is actually part of the Little Bear).
Nature in 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 prevailing worldwide sea and air currents, the Arctic area is the fall out region for long-range transport
pollutants and in some places the concentrations exceed the levels of densely populated urban areas.
The Arctic region includes sizeable potential
natural resources (oil, gas, minerals, forest - if the subarctic is included - and fish) to which modern technology and the opening up of
Russia have given significant new opportunities. The interest of the
tourism industry in the cold and exotic Arctic is also on the increase. This is for example, seen in the rise in international tourism as a significant opportunity but also as a threat.
The Arctic region is one of the last and most extensive continuous
wilderness areas in the world and its significance in preserving
biodiversity and
genotypes is considerable. The increasing presence of people fragments vital habitats. The Arctic is particularly susceptible to the abrasion of
groundcover and to the disturbance of the rare reproduction places of the animals that are characteristic to the region.

AMAP - the Arctic Monitoring and Assessment ProgrammeFrom the perspective of positive development in the Arctic region, an environmental impact assessment (EIA) is in a key position. In the Arctic region, it is important that in a process, special attention is given to assessing social impacts. It is generally known that scientific information focused on the Arctic region is insufficient, so the actors conducting an EIA do not get sufficient material in order to compile a precise assessment.
Developing a dialogue between new actors in the region, business life and the local population is important so that mutual understanding and often conflicting needs for development can be improved. Improving access to information by local inhabitants, well functioning participatory planning, and ensuring the optimum use of its results are part of this activity. The horizontal processing of administration by different sectors in society that is required for an EIA necessitates for its support the production of strong multidisciplinary information. Managing and analyzing the above-mentioned multidimensional and demanding process requires combining many scientific fields and methods and further scientific analysis and development of functional models.
The Arctic region is one of the important focuses of international political interest. International Arctic cooperation got underway on a broad scale well over ten years ago. The International Arctic Science Committee (IASC), hundreds of scientists and specialists of the Arctic Council, the Barents Council and its regional cooperation have compiled high quality information
The Arctic has never been under the political control of any nation, although some nations' militaries have attached a strategic importance to the region. In the 1950s and 1960s, the arctic was often used by
submarines to test new weapons, sonar equipment, and depth testing.
During the
Cold War, the Arctic region was extensively monitored by the
United States military, since it was the opinion of the said military that the first warnings of a
Soviet Union nuclear strike would have been indicated by
ICBMs launched over the North Pole towards the
United States. The United States placed such importance on the region that two military decorations, the
Arctic Service Ribbon and
Coast Guard Arctic Service Medal, were established for military duty performed within the arctic circle.
