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

Ports and terminals:

Alexandria (Egypt), Algiers (Algeria), Antwerp (Belgium), Barcelona

(Spain), Buenos Aires (Argentina), Casablanca (Morocco), Colon

(Panama), Copenhagen (Denmark), Dakar (Senegal), Gdansk (Poland),

Hamburg (Germany), Helsinki (Finland), Las Palmas (Canary Islands,

Spain), Le Havre (France), Lisbon (Portugal), London (UK), Marseille

(France), Montevideo (Uruguay), Montreal (Canada), Naples (Italy),

New Orleans (US), New York (US), Oran (Algeria), Oslo (Norway),

Peiraiefs or Piraeus (Greece), Rio de Janeiro (Brazil), Rotterdam

(Netherlands), Saint Petersburg (Russia), Stockholm (Sweden)

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 coast of US; the International Maritime Bureau reports the territorial waters of littoral states and offshore Atlantic waters as high risk for piracy and armed robbery against ships, particularly in the Gulf of Guinea off West Africa, the east coast of Brazil, and the Caribbean Sea; numerous commercial vessels have been attacked and hijacked both at anchor and while underway; hijacked vessels are often disguised and cargoes stolen; crews have been robbed and stores or cargoes stolen

Transnational Issues ::Atlantic Ocean

Disputes - international:

some maritime disputes (see littoral states)

@Australia (Australia-Oceania)

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 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. It boasted one of the OECD's fastest growing economies during the 1990s, a performance due in large part to economic reforms adopted in the 1980s. Long-term concerns include climate-change issues such as the depletion of the ozone layer and more frequent droughts, and management and conservation of coastal areas, especially the Great Barrier Reef.
