To the east, the boundaries of the ocean proper are Europe: the Strait of Gibraltar (where it connects with the Mediterranean Seaone of its marginal seasand, in turn, the Black Sea, both of which also touch upon Asia) and Africa. The Atlantic Ocean is home to a diverse array of sea life, both those we can observe at the surface, and those all but hidden from human eyes. [50], In many places, the continental shelf and continental slope are covered in thick sedimentary layers. The Atlantic Ocean has an average depth (with its seas) of 11,962 feet (3,646 meters) and a maximum depth of 27,493 feet (8,380 meters) in the Puerto Rico Trench, north of the island of Puerto Rico. The Kiel Canal (Germany), Oresund (Denmark-Sweden), Bosporus (Turkey), Strait of Gibraltar (Morocco-Spain), and the Saint Lawrence Seaway (Canada-US) are important strategic Other species in North Atlantic waters aren't faring as well.

The Atlantic is, generally speaking, S Besides major transatlantic transportation and communication routes, the Atlantic offers abundant petroleum deposits in the sedimentary rocks of the continental shelves. History. [41], The South Atlantic is dominated by the anti-cyclonic southern subtropical gyre. The Atlantic has contributed significantly to the development and economy of surrounding countries. [36], There are five intermediate waters: four low-salinity waters formed at subpolar latitudes and one high-salinity formed through evaporation. The opening of the Northern Atlantic closely followed the margins of its predecessor, the Iapetus Ocean, and spread from the Central Atlantic in six stages: IberiaNewfoundland, PorcupineNorth America, EurasiaGreenland, EurasiaNorth America.

Sunlight entering the water may travel about 1,000 m into the oceans under the right conditions, but there is rarely any significant light beyond 200 m.The upper 200 m (656 ft) of oceans is called the euphotic, or "sunlight," zone. 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). Other hunter-gatherers followed in waves interrupted by large-scale hazards such as the Laacher See volcanic eruption, the inundation of Doggerland (now the North Sea), and the formation of the Baltic Sea. The oceans name, derived from Greek mythology, means the Sea of Atlas. It is second in size to the Pacific Ocean. [49], The Atlantic Ocean is underlain mostly by dense mafic oceanic crust made up of basalt and gabbro and overlain by fine clay, silt and siliceous ooze on the abyssal plain. The passive margins of the Atlantic Ocean provide for wide continental shelves in North America, Northwest Europe, and the southern coast of South America. This group of people not only expanded over the whole of Africa, but also started to disperse out of Africa into Asia, Europe, and Australasia around 65,000 years ago and quickly replaced the archaic humans in these regions.

Ft. 144 S Halifax Ave #26, DAYTONA BEACH, FL The 20 East meridian, running south from Cape Agulhas to Antarctica defines its border. North Atlantic Central Water can be divided into the Eastern and Western North Atlantic central Water since the western part is strongly affected by the Gulf Stream and therefore the upper layer is closer to underlying fresher subpolar intermediate water. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone. In the early 19th century it was discovered that the southern Sargasso Sea is the spawning ground for both the European and American eel and that the former migrate more than 5,000km (3,100mi) and the latter 2,000km (1,200mi). [18], The Atlantic has irregular coasts indented by numerous bays, gulfs and seas. This involved little guesswork because the idea of sonar is straightforward with pulses being sent from the vessel, which bounce off the ocean floor, then return to the vessel. Scientists are also concerned that females, potentially facing environmental stress, are not reproducing at a rate fast enough to rebound the declining population.

Atlantic Ocean, body of salt water covering approximately one-fifth of Earths surface and separating the continents of Europe and Africa to the east from those of North and South America to the west. Climatic zones vary with latitude; the warmest zones stretch across the Atlantic north of the equator. Such a minuscule amount of light penetrates beyond a depth of 200 m that photosynthesis is no longer possible.The aphotic, or "midnight," zone exists in depths below 1,000 m (3,280 ft). In contrast, 87kya-old shell middens in Portugal, Denmark, and Brazil generated thousands of tons of debris and artefacts. [71] During the Last Glacial Maximum (LGM) 20,000 years ago humans had to abandon their initial settlements along the European North Atlantic coast and retreat to the Mediterranean. Due to a consistently strong wind shear and a weak Intertropical Convergence Zone, South Atlantic tropical cyclones are rare. [36], The North Atlantic Deep Water (NADW) is a complex of four water masses, two that form by deep convection in the open ocean Classical and Upper Labrador Sea Water and two that form from the inflow of dense water across the Greenland-Iceland-Scotland sill Denmark Strait and Iceland-Scotland Overflow Water.
