The slave trade was officially abolished in the British Empire and the United States in 1808, and slavery itself was abolished in the British Empire in 1838 and in the United States in 1865 after the Civil War. From Columbus to the Industrial Revolution Trans-Atlantic trade, including colonialism and slavery, became crucial for Western Europe.

Growth was more rapid in non-absolutist countries, such as Britain and the Netherlands, and more limited in absolutist monarchies, such as Portugal, Spain, and France, where profit mostly or exclusively benefited the monarchy and its allies. Trans-Atlantic trade also resulted in increasing urbanization: in European countries facing the Atlantic, urbanization grew from 8% in 1300, 10.1% in 1500, to 24.5% in 1850; in other European countries from 10% in 1300, 11.4% in 1500, to 17% in 1850.

A much vaguer, nameless boundary, between the North American and South American plates, intersects the MAR near or just north of the Fifteen-Twenty Fracture Zone, approximately at 16°N. In the 1870s, the Challenger expedition discovered parts of what is now known as the Mid-Atlantic Ridge, or: The remainder of the ridge was discovered in the 1920s by the German Meteor expedition using echo-sounding equipment.
Between the 15th century and 1888, when Brazil became the last part of the Americas to end the slave trade, an estimated ten million Africans were exported as slaves, most of them destined for agricultural labour.

Some of these canyons extend along the continental rises and farther into the abyssal plains as deep-sea channels. In 1922 a historic moment in cartography and oceanography occurred.
The exploration of the MAR in the 1950s led to the general acceptance of seafloor spreading and plate tectonics. Most of the MAR runs under water but where it reaches the surfaces it has produced volcanic islands.
The third group, "continuously increasing trend since 1950", is only found in the Indian Ocean and Western Pacific. In the North-East Atlantic total catches decreased between the mid-1970s and the 1990s and reached 8.7 million tons in 2013.
In the 1953 definition it extends south to Antarctica, while in later maps it is bounded at the 60° parallel by the Southern Ocean. The Atlantic has irregular coasts indented by numerous bays, gulfs and seas.
Arctic cod reached its lowest levels in the 1960s–1980s but is now recovered.
The apparent fit between the coastlines of the two continents was noted on the first maps that included the South Atlantic and it was also the subject of the first computer-assisted plate tectonic reconstructions in 1965.
In 1973 late American geoscientist Paul S.

Blue whiting reached a 2.4 million tons peak in 2004 but was down to 628,000 tons in 2013.
