Every summer, over 40 million penguins
每年夏天 超过四千万只企鹅
take to the Southern Ocean to feed.
涌入南冰洋觅食
They're joined by thousands of whales.
随之一起的还有数千头鲸鱼
Minkes are the most numerous.
绝大部分是小须鲸
They all come here to harvest the richest ocean on Earth.
它们来到这地球上最丰饶的海洋
Southern humpbacks
南方的座头鲸
have travelled 4,000 miles from the equator
从赤道出发 长途跋涉四千英里
to get here in time for the Antarctic summer.
以赶上南极的夏天
Each year, the sea ice that surrounds Antarctica melts,
每年 环绕南极的海冰融化时
effectively halving the size of the continent
大洲的面积将会减半
and exposing rich waters around its coastline.
沿海岸线的丰饶海水重见天日
It's the most spectacular seasonal change
这是我们地球上
occurring anywhere on our planet.
最壮观的季节转换
The remnants of the sea ice are occupied by sunbathing seals
沐浴着阳光的海豹慵懒地躺在浮冰上
that have been here all winter.
整个冬季它们都在这
But new arrivals are following the retreating ice edge.
但随着冰雪融去 有新客到访
And they have come here to hunt.
它们来此捕食
