Arctic. The Arctic Circle, currently at roughly 66° north of the Equator, defines the boundary of the Arctic seas and lands. A political map showing land ownership within the Arctic region. Artificially coloured topographical map of the Arctic region. MODIS image of the Arctic. The Arctic (/ ˈɑːrtɪk / or / ˈɑːrktɪk /) [1][Note 1] is a ...
The Arctic Circle is one of the two polar circles, and the most northerly of the five major circles of latitude as shown on maps of Earth at about 66° 34' N. [1] Its southern equivalent is the Antarctic Circle. The Arctic Circle marks the southernmost latitude at which, on the winter solstice (which is the shortest day of the year) in the ...
The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. [ 1 ] It spans an area of approximately 14,060,000 km 2 (5,430,000 sq mi) and is the coldest of the world's oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea ...
Geographical zone. The five main latitude regions of Earth's surface comprise geographical zones, [1] divided by the major circles of latitude. The differences between them relate to climate. They are as follows: The North Frigid Zone, between the North Pole at 90° N and the Arctic Circle at 66°33′50.1″ N, covers 4.12% of Earth's surface.
Polar regions of Earth. The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles. These high latitudes are dominated by floating sea ice covering much of the Arctic Ocean in the ...
The Northwest Passage (NWP) is the sea lane between the Atlantic and Pacific oceans through the Arctic Ocean, along the northern coast of North America via waterways through the Arctic Archipelago of Canada. [1][2][3][4] The eastern route along the Arctic coasts of Norway and Siberia is accordingly called the Northeast Passage (NEP).
Appearance. hide. A map of the Arctic. The red line is the 10 °C isotherm in July, commonly used to define the Arctic region; also shown is the Arctic Circle. The white area shows the average minimum extent of sea ice in summer as of 1975. [ 1 ] The climate of the Arctic is characterized by long, cold winters and short, cool summers.
The North American Arctic is on the left. The North American Arctic is composed of the northern polar regions of Alaska (USA), Northern Canada and Greenland. [ 1 ] Major bodies of water include the Arctic Ocean, Hudson Bay, the Gulf of Alaska and North Atlantic Ocean. [ 2 ] The North American Arctic lies above the Arctic Circle. [ 3 ]
