The Atlantic Ocean is the second largest of the world’s oceans, covering an area of about 85,133,000 km². It occupies roughly 17% of Earth’s surface and nearly 24% of the planet’s ocean water. The ocean forms a long, S-shaped basin stretching between Europe and Africa to the east and the Americas to the west. As part of the interconnected World Ocean, it connects with the Arctic Ocean in the north, the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean toward Antarctica. The Equator divides the Atlantic into two major parts: the North Atlantic Ocean and the South Atlantic Ocean.
The climate and water temperatures of the Atlantic vary greatly depending on latitude. The South Atlantic generally maintains warm conditions throughout the year because much of its basin lies in tropical and subtropical regions. In contrast, the North Atlantic includes temperate and subarctic zones where seasonal temperature changes are strong and colder waters dominate the northern parts. Powerful ocean currents play an important role in regulating climate and marine ecosystems, including the warm Gulf Stream that transports tropical water toward Europe and the colder currents flowing from the Arctic.
From a geographical and fisheries perspective, the Atlantic Ocean contains many of the world’s most productive marine ecosystems. Extensive continental shelves, underwater banks, and nutrient-rich currents create ideal conditions for marine life. Famous fishing grounds include the Grand Banks of Newfoundland, the North Sea, and large coastal shelf areas along the eastern and western Atlantic shores. These regions support large populations of commercially and recreationally important fish species such as Atlantic cod, tuna, mackerel, herring, halibut, and many pelagic predators.
The Atlantic Ocean is also one of the most important regions for recreational fishing. Anglers target a wide range of species from coastal and offshore environments, including Atlantic bluefin tuna, blue marlin, swordfish, tarpon, and numerous reef and coastal fish. Long coastlines, numerous islands, estuaries, and deep offshore waters provide a wide diversity of fishing habitats, making the Atlantic one of the most significant oceans for both global fisheries and sport angling.
