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
