The Atlantic Ocean is the second-largest of the world's oceanic divisions; with a total area of about 41.1 million square miles (106.4 million square kilometers), it covers approximately one-fifth of the Earth's surface.
The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between the Americas to the west, and Eurasia and Africa to the east.
Icebergs are common in the 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.
One of Prince Henry's early expeditions into the Atlantic occurred in 1420 with the rediscovery of Madeira.
Storms are common in the North Atlantic during northern winters, making ocean crossings more difficult and dangerous.
The south tides in the Atlantic Ocean are semi-diurnal; that is, two high tides occur during each 24 lunar hours.
The land area that drains into the Atlantic is four times that of the drainage areas feeding into either the Pacific or Indian oceans.
The Atlantic Ocean has irregular coasts indented by numerous bays, gulfs, and seas.
Highly productive fisheries of the Atlantic have been severely overfished in the twentieth century and the development of industrial scale fish farming raises further issues about maintaining healthy wild fisheries.
All these factors, taken together, tremendously enhance the Atlantic's great commercial value.
Endangered marine species of the Atlantic Ocean include the manatee, seals, sea lions, turtles, and whales.
The width of the Atlantic varies from 1,770 miles (2,848 kilometers) between Brazil and Liberia to about 3,000 miles (4,830 kilometers) between the United States and northern Africa.
Ships are subject to superstructure icing in extreme northern Atlantic from October to May.
The Atlantic Ocean is bounded on the west by North and South America.
Within the North Atlantic, ocean currents isolate a large elongated body of water known as the Sargasso Sea, in which the salinity is noticeably higher than average.
The volume of the Atlantic Ocean with its adjacent seas is 85.1 million cubic miles (354.7 million cubic kilometers) and without them 77.6 million cubic miles (323.6 million cubic kilometers).
A man-made link between the Atlantic and Pacific is provided by the Panama Canal.
The South Atlantic Ocean has an additional submarine ridge, the Walvis Ridge.
Natural resources in the Atlantic include petroleum and gas fields, fish, marine mammals (seals and whales), sand and gravel aggregates, placer deposits, polymetallic nodules, and precious stones.
The Mid-Atlantic Ridge separates the Atlantic Ocean into two large troughs with depths averaging between 12,000 - 18,000 feet (3,700 - 5,500 meters).
The average depth of the Atlantic, with its adjacent seas, is 10,932 feet (3,338 meters); without them it is 12,881 feet (3,926 meters).
The equator subdivides it into the North Atlantic Ocean and South Atlantic Ocean.
The ocean floor is dominated by the Mid-Atlantic Ridge, a rugged north-south centerline for the entire Atlantic basin, first discovered by the Challenger Expedition.
The Atlantic Ocean appears to be the second youngest of the world's oceans, after the Southern Ocean.
The Origin of the Name Atlantic Ocean. Most everyone knows the name Atlantic Ocean. ... The oldest known mention of “Atlantic” is in The Histories of Herodotus around 450 BC. In Greek, Atlantis means “Island of Atlas”, or in some context, “Sea of Atlas”.Apr 23, 2013
The Atlantic Ocean is still growing now, because of sea-floor spreading from the mid-Atlantic Ridge, while the Pacific Ocean is said to be shrinking because the sea floor is folding under itself.
The Atlantic Ocean is the second largest of the world's oceans with a total area of about 106,460,000 square kilometers (41,100,000 square miles). It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World".
The rate of North Atlantic spreading is about 25 mm/year, due to the formation of new crust at the mid-Atlantic ridge and the (relative) westward motion of the North American Plate; the Eurasian Plate is moving (relatively) eastward and sliding over the Pacific Plate and various minor plates that are sinking in the ...Jun 3, 2016
Atlantic Ocean Facts. The Atlantic Ocean borders on North America, South America, Europe, and Africa. It is the world's second largest ocean, while the Pacific Ocean is the largest. The Atlantic Ocean covers approximately 1/5th of the surface of the earth and covers approximately 29% of the world's water surface area.
It was once much wider when all the continents were joined together in the supercontinent, Pangea. The Pacific ocean basin is getting smaller because the Atlantic Ocean is opening and North America and South America are moving westward. Most of the Pacific Ocean is underlain by the Pacific plate.
You can clearly see that the North American plate is moving westward and Eurasian and Australian plates are moving eastward, squeezing the Pacific plate between them. On the other hand, All plates that share boundary in the Atlantic Ocean are receding from each other, thus making the Atlantic wider.
Cape Horn. At this spot the Atlantic and Pacific oceans meet, often in a confrontation. No land to the east, none to the west—winds sweep all the way around the world from the west.
