Thanks to technology, people have discovered interesting things.
On June 8 – World Oceans Day, the US National Geographic Society recognized the waters around Antarctica as the planet’s fifth ocean, along with the Atlantic, Pacific, and Indian Oceans. and the Arctic Ocean.

Previously, the waters around Antarctica were referred to by scientists and the press as the “Southern Ocean”, but the National Geographic Society only classifies it as the frigid southern extension of the South Pole. The Atlantic, Indian and Pacific Oceans have never been officially recognized.
Since 1999, the Southern Ocean has been recognized by the American Council on Geographical Names. But it was not until February 2021 that the US National Oceanic and Atmospheric Administration recognized this fifth ocean of the Earth.
The National Geographic Society’s decision to recognize the Southern Ocean stems from its recognition of the distinct ocean currents that surround Antarctica. Different from the previous 4 oceans defined by geography and tectonic plates.
According to studies on the Southern Ocean, this sea has a unique marine ecosystem, and has a different beauty compared to other places.
Previously, the recognition of the fifth ocean was controversial. The National Geographic Society hopes their revision of the map will help people think differently about the Southern Ocean, thereby encouraging its preservation.
The recognition of the Southern Ocean means that maps will have to be redrawn, educational programs about the ocean will have to change, and the science of studying Earth’s geography and climate in general will also have many innovations.
