June 10 (Xinhua) according to CBS, on world ocean day on the 8th local time, the National Geographic Society of the United States announced that the waters around Antarctica will be called the Southern Ocean, and officially recognized the Southern Ocean as the fifth ocean of the earth.
According to the National Geographic Society of the United States, since the National Geographic Society of the United States began mapping in 1915, it has confirmed that there are four oceans in the world - the Atlantic Ocean, the Pacific Ocean, the Indian Ocean and the Arctic Ocean. Starting from world ocean day on June 8, the Southern Ocean will be recognized as the fifth largest ocean in the world.
The Southern Ocean is not only an important home of marine ecosystem, but also the focus of the southern hemisphere. It directly surrounds Antarctica, extending from the continental coastline to 60 degrees south latitude. The boundaries of the oceans are connected to three of the other four oceans that exist on earth - the Atlantic Ocean, the Indian Ocean, and the Pacific Ocean.
But the difference between the Southern Ocean and other oceans is that it is not determined by the surrounding land to a large extent, but because there is an ocean current inside, which is very unique.
The current is estimated to be about 34 million years old, making the ecology of the southern ocean so unique that it provides a unique habitat for thousands of species, the National Geographic Society said in its journal.
2021年早些时候，美国国家海洋和大气管理局(NOAA)也承认了南大洋的称号，美国地理名称委员会(U.S. Board on Geographic Names)自1999年以来也承认了南大洋。但是，美国国家地理学会在8日声明中表示，世界各地的科学家多年来一直在试图确定一个官方名称。
In early 2021, the National Oceanic and Atmospheric Administration (NOAA) also recognized the Southern Ocean, and the U.S. board on geographic names has recognized the Southern Ocean since 1999. However, scientists around the world have been trying to identify an official name for many years, the National Geographic Society said in a statement on the 8th.
According to the National Geographic Society of the United States, the Southern Ocean will receive the same treatment as the four oceans and will be included in the world ocean science books.
