A fifth ocean on the planet – World


The Earth had four oceans: the Atlantic, the Pacific, the Indian and the Arctic. As of this week, it has a fifth, the southern ocean, announced National Geographic. Its cartographers have, in fact, announced that the rapid current which surrounds Antarctica distinguishes the waters of this region and that the latter deserve their own name, the Southern Ocean.
“The Southern Ocean has been recognized for a long time by scientists but since no international agreement has ever been found, we had never officially recognized it”, explains Alex Tait, geographer for the National Geographic Society, on the site of the institution.
If the first four oceans are defined by the continents which surround them, the Southern Ocean is, for its part, defined by a current. As National Geographic points out, scientists estimate that the Antarctic Circumpolar Current (ACC) arose from the opening between Antarctica and South America that occurred nearly 34 million years ago.
