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
international agreements:
NA
Note:
major chokepoint is the southern Chukchi Sea (northern access to the
Pacific Ocean via the Bering Strait); ships subject to superstructure
icing from October to May; 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

@Arctic Ocean, Economy
Overview:
Economic activity is limited to the exploitation of natural resources,
including petroleum, natural gas, fish, and seals.
@Arctic Ocean, Communications
Ports:
Churchill (Canada), Murmansk (Russia), Prudhoe Bay (US)
Telecommunications:
no submarine cables
Note:
sparse network of air, ocean, river, and land routes; the Northwest
Passage (North America) and Northern Sea Route (Eurasia) are important
seasonal waterways
