  Arctic Ocean
     Introduction Arctic Ocean
                              Background: The Arctic Ocean is the smallest of
                                          the world's five oceans (after the
                                          Pacific Ocean, Atlantic Ocean,
                                          Indian Ocean, and the recently
                                          delimited Southern Ocean). The
                                          Northwest Passage (US and Canada)
                                          and Northern Sea Route (Norway and
                                          Russia) are two important seasonal
                                          waterways. A sparse network of air,
                                          ocean, river, and land routes
                                          circumscribes the Arctic Ocean.
     Geography Arctic Ocean
                                Location: body of water between Europe, Asia,
                                          and North America, mostly north of
                                          the Arctic Circle
                  Geographic coordinates: 90 00 N, 0 00 E
                          Map references: Arctic Region
                                    Area: total: 14.056 million sq km
                                          note: includes Baffin Bay, Barents
                                          Sea, Beaufort Sea, Chukchi Sea, East

                                          tributary water bodies
                      Area - comparative: slightly less than 1.5 times the
                                          size of the US
                               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
                                          landmasses; 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 Lomonosov 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 ice locked from
                                          October to June; ships subject to
                                          superstructure icing from October to
            Environment - current issues: endangered marine species include
                                          walruses and whales; fragile
                                          ecosystem slow to change and slow to
                                          recover from disruptions or damage;
                                          thinning polar icepack
                        Geography - 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;
                                          snow cover lasts about 10 months
     Economy Arctic Ocean
                       Economy - overview: Economic activity is limited to the
                                           exploitation of natural resources,
                                           including petroleum, natural gas,
                                           fish, and seals.
     Transportation Arctic Ocean

                                          (Russia), Prudhoe Bay (US)
                   Transportation - note: sparse network of air, ocean, river,
                                          and land routes; the Northwest
                                          Passage (North America) and Northern
                                          Sea Route (Eurasia) are important
                                          seasonal waterways
     Transnational Issues Arctic Ocean
                Disputes - international: some maritime disputes (see littoral
                                          states); Russia is the first state
                                          to submit data to the UN Commission
                                          on the Limits of the Continental
                                          Shelf to extend its continental
                                          shelf by claiming two undersea
                                          ridges in the Arctic Ocean
