ve: 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 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
