Unlike most areas of the world, the shallower waters on the Antarctic continental shelf are actually slightly colder than the deeper waters of the Southern Ocean.

和世界上大部分区域不同，南极大陆架的浅水区域实际上要比南印度洋的深水区稍微冷一些。

Krill, the whales' main source of food, are threatened by higher ocean temperatures and melting sea ice around the Antarctic, which would in turn hurt the whales' chances of survival.

在南极地区，由于海洋温度的上升和海冰的融化，露脊鲸主要的食物来源南极磷虾受到了严重威胁，这反过来也危及到了鲸类的生存。

They will continue their journey on a naval ship, which will release them into the ocean in their Antarctic habitat.

随后，这些企鹅将搭乘一艘海军舰艇继续旅程，直到最终抵达南极海域。

假如支撑西南极洲冰盖的沿岸冰架持续解体，那么冰盖就会泄入海洋，百年之内海平面便将上升数米。

Warming of the middle depths of the Southern Ocean could unleash the "widespread collapse" of the West Antarctic icesheet by the year 3000, it says.

该预测认为，南大洋中间深度水域升温到3000年可能会导致南极洲西部冰原的“大面积崩溃”。
