双语阅读|关于第五大洋-“新”南大洋,我们需要了解的5件事 万物探索中国之最( 二 )

3. It's Separated From Other Oceans by Currents, Not Continents 它与其他海洋的分隔是洋流 , 而不是大陆Separating bodies of salt water from one another is a difficult task, and it's usually done with landmasses: Is there a continent between these two oceans? Great! Let's give them different names! However, the Southern Ocean is an oddball because there's no continent separating it from the Indian, Atlantic or Pacific oceans.
将咸水从彼此之间分离是一项艰巨的任务 , 通常是通过陆地来完成的:这两个海洋之间有大陆吗?太棒了!让我们给它们取不同的名字吧!然而 , 南大洋是一个奇怪的地方 , 因为没有大陆将它与印度洋、大西洋或太平洋分开 。
Instead, the waters of the Southern Ocean are kept close to the southern continent by a fast-moving current called the Antarctic Circumpolar Current (ACC), which flows west to east around Antarctica. The waters of the ACC are colder and less salty than those of its neighboring oceans.
相反 , 南大洋的海水被一种名为南极环极流(ACC)的快速移动的洋流保持在靠近南极大陆的位置 , 该洋流围绕南极洲从西向东流动 。与邻近海域相比 , ACC水域温度更低 , 盐度更低 。
