The Atlantic Ocean appears to be the youngest of the world's oceans. Evidence indicates that it did not exist prior to 100 million years ago, when the continents that formed from the breakup of the ancestral supercontinent, Pangaea, were being rafted apart by the process of seafloor spreading. The Atlantic has been extensively explored since the earliest settlements were established along its shores. The Vikings, Portuguese, and Christopher Columbus were the most famous among its early explorers. After Columbus, European exploration rapidly accelerated, and many new trade routes were established. As a result, the Atlantic became and remains the major artery between Europe and the Americas (known as transatlantic trade). Numerous scientific explorations have been undertaken, including those by the German Meteor expedition, Columbia University's Lamont Geological Observatory, and the U.S. Navy Hydrographic Office.
The ocean has also contributed significantly to the development and economy of the countries around it. Besides its major " transatlantic" transportation and communication routes, the Atlantic offers abundant petroleum deposits in the sedimentary rocks of the continental shelves and the world's richest fishing resources, especially in the waters covering the shelves. The major species of fish caught are cod, haddock, hake, herring, and mackerel. The most productive areas include the Grand Banks off Newfoundland, the shelf area off Nova Scotia, Georges Bank off Cape Cod, the Bahama Banks, the waters around Iceland, the Irish Sea, the Dogger bank of the North Sea, and the Falkland Banks. Eel, lobster, and whales have also been taken in great quantities. All these factors, taken together, tremendously enhance the Atlantic's great commercial value. Because of the threats to the ocean environment presented by oil spills, plastic debris, and the incineration of toxic wastes at sea, various international treaties exist to reduce some forms of pollution.
Location: body of water between Africa, Europe, the Southern Ocean, and the Americas
Geographic coordinates: 0 00 N, 25 00 W

WorldArea:
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. Storms are common in the North Atlantic during northern winters, making ocean crossings more difficult and dangerous.
