For the study, the researchers followed 321 whales living in the Atlantic, Pacific and Southern oceans.

在这项研究中，研究人员对生活在大西洋、太平洋和南冰洋的321头鲸鱼进行跟踪。

Because they live underwater where we can't easily see them - and often in remote areas, like the southern ocean.

因为它们生活在水下，我们无法轻易看到其身影，而且它们通常在南大洋等偏远地区活动。

Here's how it works: Researchers attached data loggers to the backs of 169 albatrosses in the Southern and Indian oceans.

研究人员在南大洋和印度洋的169只信天翁的背部系上数据记录器。

But these additional tools and bodies weighed down the ship as it battled the storms of the southern ocean.

但是这些额外的工具和身体在与南大洋的风暴作斗争时拖累了这艘船。

Almost all of the world, except for parts of the southern oceans, are likely to be warmer than the recent past, which is defined as 1981 to 2010.

除了南大洋部分地区外，几乎全球所有地区都可能比最近的1981年到2010年间气温上升。

Australian experts taking part in an international program to take a census of marine life in the southern ocean collected specimens from up to 6,500 feet beneath the surface.

澳大利亚专家参加了一项国际计划，对南大洋的海洋生物进行普查，他们从水下6500英尺的地方采集标本。

The southern oceans around Antarctica produce only about 3 percent of the world's phytoplankton, far too little, it would seem, to support a complex ecosystem, and yet it does.

在南极洲周围的南部海洋，只出产世界上大约3%的浮游植物，少得似乎远远不足以维持一个复杂的生态系统，而它们却维持了。

Coral reefs, for example, support over 4000 types of fish, along with sponges, crustaceans, and many other organisms. So, exactly when and how did the Notothenioids come to dominate the southern ocean?

例如，珊瑚礁栖息着 4000 多种鱼类，还有海绵、甲壳类动物和许多其他生物。那么，Notothenioids 究竟是何时以及如何开始统治南大洋的呢？
