Oceans :: ATLANTIC OCEAN
Introduction :: ATLANTIC OCEAN
The Atlantic Ocean is the second largest of the world's five oceans (after the Pacific Ocean, but larger than the Indian Ocean, Southern Ocean, and Arctic Ocean). The Kiel Canal (Germany), Oresund (Denmark-Sweden), Bosporus (Turkey), Strait of Gibraltar (Morocco-Spain), and the Saint Lawrence Seaway (Canada-US) are important strategic access waterways. The decision by the International Hydrographic Organization in the spring of 2000 to delimit a fifth world ocean, the Southern Ocean, removed the portion of the Atlantic Ocean south of 60 degrees south latitude.
Geography :: ATLANTIC OCEAN
body of water between Africa, Europe, the Arctic Ocean, the Americas, and the Southern Ocean0 00 N, 25 00 WPolitical Map of the Worldtotal: 76.762 million sq kmnote: 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 bodiesabout 7.5 times the size of the US111,866 kmtropical cyclones (hurricanes) develop off the coast of Africa near Cabo Verde and move westward into the Caribbean Sea; hurricanes can occur from May to December but are most frequent from August to Novembersurface usually covered with sea ice in Labrador Sea, Denmark Strait, and coastal portions of the Baltic Sea from October to June; surface dominated by two large gyres (broad, circular systems of currents), one in the northern Atlantic and another in the southern Atlantic; the ocean floor is dominated by the Mid-Atlantic Ridge, a rugged north-south centerline for the entire Atlantic basinmajor surface currents: clockwise North Atlantic Gyre consists of the warm Gulf Stream in the west, the North Atlantic Current in the north, the cold Canary Current in the east, and the North Equatorial Current in the south; the counterclockwise South Atlantic Gyre composed of the warm Brazil Current in the west, the South Atlantic Current in the south, the cold Benguela Current in the east, and the South Equatorial Current in the northmean depth: -3,646 melevation extremes: lowest point: Milwaukee Deep in the Puerto Rico Trench -8,605 mhighest point: sea level 0 moil and gas fields, fish, marine mammals (seals and whales), sand and gravel aggregates, placer deposits, polymetallic nodules, precious stonesicebergs 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)unsustainable exploitation of fisheries (over fishing, bottom trawling, drift net fishing, discards, catch of non-target species); endangered marine species include the manatee, seals, sea lions, turtles, and whales; pollution (maritime transport, discharges, offshore drilling, oil spills); 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 Seamajor 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

etymology: name derives from the Greek description of the waters beyond the Strait of Gibraltar, Atlantis thalassa, meaning "Sea of Atlas"
Economy :: ATLANTIC OCEAN
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
major seaport(s): 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)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
Military and Security :: ATLANTIC OCEAN
West African piracy is a continuing threat with 33 attacks in 2017 compared to 36 in 2016; Nigerian pirates are very aggressive, operating as far as 200 nm offshore and boarding 20 ships in 2017
