or Arctic Ocean)
Coastline:
111,866 km
Disputes:
some maritime disputes (see littoral states)
Climate:
tropical cyclones (hurricanes) develop off the coast of Africa near Cape
Verde and move westward into the Caribbean Sea; hurricanes can occur from
May to December, but are most frequent from August to November
Terrain:
surface usually covered with sea ice in Labrador Sea, Denmark Strait, and
Baltic Sea from October to June; clockwise warm water gyre (broad, circular
system of currents) in the north Atlantic, counterclockwise warm water gyre
in the south Atlantic; the ocean floor is dominated by the Mid-Atlantic
Ridge, a rugged north-south centerline for the entire Atlantic basin;
maximum depth is 8,605 meters in the Puerto Rico Trench
Natural resources:
oil and gas fields, fish, marine mammals (seals and whales), sand and gravel
aggregates, placer deposits, polymetallic nodules, precious stones
Environment:
endangered marine species include the manatee, seals, sea lions, turtles,
and whales; municipal sludge pollution off eastern US, southern Brazil, and
eastern Argentina; oil pollution in Caribbean Sea, Gulf of Mexico, Lake
Maracaibo, Mediterranean Sea, and North Sea; industrial waste and municipal
sewage pollution in Baltic Sea, North Sea, and Mediterranean Sea; icebergs
common in Davis Strait, Denmark Strait, and the northwestern Atlantic from
February to August and have been spotted as far south as Bermuda and the
Madeira Islands; icebergs from Antarctica occur in the extreme southern
Atlantic
Note:
ships subject to superstructure icing in extreme north Atlantic from October
to May and extreme south Atlantic from May to October; persistent fog can be
a hazard to shipping from May to September; major choke points include the
Dardanelles, Strait of Gibraltar, access to the Panama and Suez Canals;
strategic straits include the Dover Strait, Straits of Florida, Mona
Passage, The Sound (Oresund), and Windward Passage; north Atlantic shipping
lanes subject to icebergs from February to August; the Equator divides the
Atlantic Ocean into the North Atlantic Ocean and South Atlantic Ocean
Kiel Canal and Saint Lawrence Seaway are two important waterways
:Atlantic Ocean Economy
Overview:
Economic activity is limited to exploitation of natural resources,
especially fish, dredging aragonite sands (The Bahamas), and crude oil and
natural gas production (Caribbean Sea and North Sea).
