While the South Pole lies on a continental land mass, the North Pole is located in the middle of the Arctic Ocean amid waters that are almost permanently covered with constantly shifting sea ice. The sea depth at the North Pole has been measured at 4,261 m (13,980 ft) by the Russian Mir submersible in 2007 [ 1 ] and at 4,087 m (13,409 ft) by ...
To connect the Atlantic with the Pacific, the Northwest Passage goes along the Northern Canadian and Alaskan coasts, the Northeast Passage (NEP) follows the Russian and Norwegian coasts, and the Transpolar Sea Route crosses the Arctic through the North Pole. [2] The Arctic Bridge is an internal Arctic route linking Russia to Canada, and the ...
Much of the Arctic Ocean is covered by sea ice that varies in extent and thickness seasonally. The mean extent of the Arctic sea ice has been continuously decreasing in the last decades, declining at a rate of currently 12.85% per decade since 1980 from the average winter value of 15,600,000 km 2 (6,023,200 sq mi).

The Arctic Circle, at roughly 66.5° north, is the boundary of the Arctic waters and lands. The Arctic Circle is one of the two polar circles, and the northernmost of the five major circles of latitude as shown on maps of Earth at about 66° 34' N. [1] Its southern counterpart is the Antarctic Circle.
If viewed from the southern pole of Earth, the Atlantic, Indian, and Pacific Oceans can be seen as lobes extending northward from the Southern Ocean. Farther north, the Atlantic opens into the Arctic Ocean, which is connected to the Pacific by the Bering Strait, forming a continuous expanse of water. The five oceans are:
Northwest Passage routes Envisat ASAR mosaic of the Arctic Ocean (September 2007), showing the most direct route of the Northwest Passage closed (yellow line) and the Northeast Passage partially opened (blue line). The dark grey colour represents the ice-free areas, while green represents areas with sea ice.
Litke Deep is closer to North Pole at 82°24’ N and the difference between Earth's diameter at poles and equator is greater than the depth at Challenger Deep (10,925 m (35,843 ft) below sea level), around 11°22' north, nearer to equator with sea level also having the difference. Despite being 5,475 m (17,963 ft) shallower in depth below sea ...
The word Arctic comes from the Greek word ἀρκτικός (arktikos), "near the Bear, northern" [4] and from the word ἄρκτος (arktos), meaning bear. [5] The name refers either to the constellation known as 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 ...
