(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.
