6月10日电 据美国哥伦比亚广播公司报道,当地时间8日,在世界海洋日当天,美国国家地理学会宣布,南极洲周围海域将被称为南大洋,并正式承认南大洋为地球第五大洋。

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.

美国国家地理学会表示,自从1915年美国国家地理学会开始绘制地图以来,已经确认了世界上有四大洋——大西洋、太平洋、印度洋和北冰洋。从6月8日世界海洋日开始,南大洋将被认定为世界第五大洋。

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.

南大洋是海洋生态系统的重要家园,也是南半球的焦点。它直接包围着南极洲,从大陆的海岸线一直延伸到南纬60度。海洋的边界与地球上存在的其他四个大洋中的三个相连——大西洋、印度洋和太平洋。

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.

但南大洋与其它大洋的不同之处在于,它在很大程度上不是由周围的陆地决定的,而是由于内部有一股洋流,这片水域很独特。

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.


美国国家地理学会在其杂志上表示,这股洋流估计大约有3400万年的历史,使南大洋的生态如此独特,为数千种物种提供了独特的栖息地。

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.


美国国家地理学会称,南大洋将受到和四大洋一样的待遇,将被收录在世界大洋科普书中。

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.
