Map references: Arctic Region

Area:
total: 14.056 million sq km
note: includes Baffin Bay, Barents Sea, Beaufort Sea, Chukchi Sea,
East Siberian Sea, Greenland Sea, Hudson Bay, Hudson Strait, Kara Sea,
Laptev Sea, Northwest Passage, and other tributary water bodies

Area - comparative: slightly less than 1.5 times the size of the US;
smallest of the world's four oceans (after Pacific Ocean, Atlantic
Ocean, and Indian Ocean)

Coastline: 45,389 km

Climate: polar climate characterized by persistent cold and relatively
narrow annual temperature ranges; winters characterized by continuous
darkness, cold and stable weather conditions, and clear skies; summers
characterized by continuous daylight, damp and foggy weather, and weak
cyclones with rain or snow

Terrain: central surface covered by a perennial drifting polar icepack
that averages about 3 meters in thickness, although pressure ridges
may be three times that size; clockwise drift pattern in the Beaufort
Gyral Stream, but nearly straight line movement from the New Siberian
Islands (Russia) to Denmark Strait (between Greenland and Iceland);
the icepack is surrounded by open seas during the summer, but more
than doubles in size during the winter and extends to the encircling
land masses; the ocean floor is about 50% continental shelf (highest
percentage of any ocean) with the remainder a central basin
interrupted by three submarine ridges (Alpha Cordillera, Nansen
Cordillera, and Lomonsov Ridge)

Elevation extremes:
lowest point: Fram Basin -4,665 m
highest point: sea level 0 m

Natural resources: sand and gravel aggregates, placer deposits,
polymetallic nodules, oil and gas fields, fish, marine mammals (seals
and whales)

Natural hazards: ice islands occasionally break away from northern
Ellesmere Island; icebergs calved from glaciers in western Greenland
and extreme northeastern Canada; permafrost in islands; virtually
icelocked from October to June; ships subject to superstructure icing
from October to May

Environment - current issues: endangered marine species include
walruses and whales; fragile ecosystem slow to change and slow to
recover from disruptions or damage

Environment - international agreements:
party to : none of the selected agreements
signed, but not ratified: none of the selected agreements

Geography - note: major chokepoint is the southern Chukchi Sea
(northern access to the Pacific Ocean via the Bering Strait);
