Atlantic ocean

map of the Atlantic ocean

the Atlantic ocean (short: Atlantic) is to the Pacific the second largest Weltmeer. It resulted from the division of the once which is connected Urkontinents and separates Europe and Africa from the American continent. With its Nebenmeeren(among other things) The ocean has Mediterranean, Nord- and Baltic Sea a surface of approx. 106,2 millions km ² and covers a fifth of the earth's surface. The bottom of the sea is by the Mid-Atlantic Ridge, that up to 3000 m over the deep sea soil, separately into west and eastAtlantic hollow rises. The maximum depth is reached with 9.219 m in the Milwaukeetief, a part of the Puerto Rico ditch. The gulf stream, which comes from the Karibik and pulls crosswise over the Atlantic until Greenland,is responsible for the relatively mild climate also at the northEuropean coasts. The Atlantic is, because of the intensive navigation on the Nebenmeeren and the transit traffic between Europe and North America, the busiest Weltmeer.

Table of contents

name origin

the name goes back on the Greek mythology. With the designation “Atlantìs thálassa” (griech.: Ἀτλαντἰς θάλασσα; dt.: “Sea of the Atlas “), which is for the first time with Herodot (Hdt. I 202.4), meant the Greeks the sea beyond the so-called columns of the Herakles, i.e. west the road of Gibraltar.

situationand delimitation

the Atlantic, which is almost exclusively in the west hemisphere of the earth, is appropriate for the Antarctic between the arctic in the north , Europe in the northeast , Africa in the southeast , in the south, South America in the southwest and North America in the northwest. The Atlanticdue to its pronounced north south adjustment is divided also into North Atlantic and south Atlantic.


the Atlantic has a number of important central, edge and Binnenmeere:

Kind designation expansion
marginal sea European North Sea 1.380.000 km ²
marginal sea North Sea 575,000 km ²
Binnenmeer Baltic Sea 413,000 km ²
Mediterranean European Mediterranean 2.596.000 km ²
Binnenmeer black sea 424,000 km ²
Mediterranean American Mediterranean 4.354.000 km ²
Binnenmeer Hudsonbucht 1.230.000 km ²
marginal sea Baffinbucht xx km ²

connections to the othersWeltmeeren

the Denmark route, which lie between Greenland and Iceland, as well as the Davisstrasse with following Baffin Bay between Canada and Greenland, are the northern linkages to the arctic ocean. East of Iceland the European North Sea goes directly into the arctic one Ocean over. The largest connected connection of the Atlantic with the remaining oceans extends south cape the Agulhas. The Meridian running by this place separates the Atlantic from the Indian ocean. In the south forms the 60. Degree of latitude those, throughthe Antarctic contract, arbitrarily drawn border to the Antarctic Ocean. The connection to the Pacific ocean production by the Magellan route and waters south cape the Hoorn.

Beside these natural interfaces still further connections created by humans exist: The Suez channel, der daseuropäische Mittelmeer mit dem Roten Meer und der Panamakanal, der das amerikanische Mittelmeer mit dem Pazifik verbindet.

bottom of the sea

within the Atlantiks and/or. on its bottom of the sea is more highly and very more elongated Midocean back, many lower thresholds, deep sea basins, deep sea gutters and different sea lows.

To the midocean backs belongs the Mid-Atlantic Ridge, which pulls itself approximately in the center of the Atlantiks from north to south by the ocean. Ita diverging shelf border represents . The ocean floor becomes ever older, the further it is distant from the midocean back. By the lava constantly out-pouring from the midocean back the Atlantic widens itself and shifts apart the continents. To the deep sea gutters and/or.The Puerto Rico ditch with its 9,219 m Milwaukeetief which is under NN , which represents the deepest place of the Atlantiks , belongs to sea lows.

One can divide the Atlantic in north, central and south Atlantic. Here the soils of the Zentralatlantiks exhibit the largest age- here the ocean opened first.


some the largest islands of the earth are appropriate for Greenland, Iceland, Great Britain, Ireland and Newfoundland in the Atlantic ocean , so for example. Inselgruppen in the Atlantic are the Kanaren, the Azores, the Bahamas, the Antilleses, the Kapverden and the Falklandinseln. Smaller, isolated islands are larva Irish Republican Army, Ascension, pc. Helena and Tristan there Cunha.
