(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, the dredging of aragonite sands
(The Bahamas), and production of crude oil and natural gas
(Caribbean Sea, Gulf of Mexico, and North Sea).

Introduction Australia
Background:
Aboriginal settlers arrived on the continent from Southeast Asia
about 40,000 years before the first Europeans began exploration in
the 17th century. No formal territorial claims were made until 1770,
when Capt. James COOK took possession in the name of Great Britain.
Six colonies were created in the late 18th and 19th centuries; they
federated and became the Commonwealth of Australia in 1901. The new
country took advantage of its natural resources to rapidly develop
its agricultural and manufacturing industries and to make a major
contribution to the British effort in World Wars I and II. In recent
decades, Australia has transformed itself into an internationally
competitive, advanced market economy. Long-term concerns include
pollution, particularly depletion of the ozone layer, and management
and conservation of coastal areas, especially the Great Barrier
Reef. A referendum to change Australia's status, from a commonwealth
headed by the British monarch to a republic, was defeated in 1999.
