in the spring of 2000 todelimit a fifth world ocean, the Southern Ocean, removed the portion
of the Atlantic Ocean south of 60 degrees south.
Geography Atlantic Ocean
Location:
body of water between Africa, Europe, the Southern Ocean, and the
Western Hemisphere
Geographic coordinates:
0 00 N, 25 00 W
Map references:
Political Map of the World
Area:
total: 76.762 million sq km
note: includes Baltic Sea, Black Sea, Caribbean Sea, Davis Strait,
Denmark Strait, part of the Drake Passage, Gulf of Mexico, Labrador
Sea, Mediterranean Sea, North Sea, Norwegian Sea, almost all of the
Scotia Sea, and other tributary water bodies
Area - comparative:
slightly less than 6.5 times the size of the US
Coastline:
111,866 km
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 coastal portions of the Baltic Sea from October to June;
clockwise warm-water gyre (broad, circular system of currents) in
the northern Atlantic, counterclockwise warm-water gyre in the
southern Atlantic; the ocean floor is dominated by the Mid-Atlantic
Ridge, a rugged north-south centerline for the entire Atlantic basin
Elevation extremes:
lowest point: Milwaukee Deep in the Puerto Rico Trench −8,605 m
highest point: sea level 0 m
Natural resources:
oil and gas fields, fish, marine mammals (seals and whales), sand
and gravel aggregates, placer deposits, polymetallic nodules,
precious stones
Natural hazards:
icebergs common in Davis Strait, Denmark Strait, and the
northwestern Atlantic Ocean from February to August and have been
spotted as far south as Bermuda and the Madeira Islands; ships
subject to superstructure icing in extreme northern Atlantic from
October to May; persistent fog can be a maritime hazard from May to
September; hurricanes (May to December)
Environment - current issues:
endangered marine species include the manatee, seals, sea lions,
turtles, and whales; drift net fishing is hastening the decline of
fish stocks and contributing to international disputes; 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
Geography - note:
major chokepoints include the Dardanelles, Strait of Gibraltar,
access to the Panama and Suez Canals; strategic straits include the
Strait of Dover, Straits of Florida, Mona Passage, The Sound
(Oresund), and Windward Passage; the Equator divides the Atlantic
Ocean into the North Atlantic Ocean and South Atlantic Ocean
Economy Atlantic Ocean
Economy - overview:
The Atlantic Ocean provides some of the world's most heavily
trafficked sea routes, between and within the Eastern and Western
Hemispheres. Other economic activity includes the exploitation of
natural resources, e.g., fishing, dredging of aragonite sands (The
Bahamas), and production of crude oil and natural gas (Caribbean
Sea, Gulf of Mexico, and North Sea).
Transportation Atlantic Ocean

Transportation - note:
Kiel Canal and Saint Lawrence Seaway are two important waterways;
significant domestic commercial and recreational use of Intracoastal
Waterway on central and south Atlantic seaboard and Gulf of Mexico
