g 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); maximum depth is 4,665 meters in the
Fram Basin
Natural resources: sand and gravel aggregates, placer deposits,
polymetallic nodules, oil and gas fields, fish, marine mammals (seals
and whales)
Environment:
current issues: endangered marine species include walruses and whales;
fragile ecosystem slow to change and slow to recover from disruptions
or damage
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
international agreements: NA
Note: major chokepoint is the southern Chukchi Sea (northern access to
the Pacific Ocean via the Bering Strait); strategic location between
North America and Russia; shortest marine link between the extremes of
eastern and western Russia, floating research stations operated by the
US and Russia; maximum snow cover in March or April about 20 to 50
centimeters over the frozen ocean and lasts about 10 months
