There is more ocean on our planet than there is land, but we still know little about it. The first ship sailed all the way around the world about fivehundred years ago. And the first journey to the deepest sea floor was sixty years ago.
Great waves move across the surface of theocean, and currents of cold and warm water move past our continents. The biggest animals on our planet swim around the Southern Ocean, and in the hottest parts of the ocean we can find animals that live without light. It is a strange world and we are just beginning to know it
地球上的海洋面积比陆地面积大，我们对海洋却知之甚少。约500年前，人们第一次乘船环游了世界，而首次探索海床最深处的旅程也不过发生在60年前。
巨浪席卷海面，冷暖洋流流经我们的各大洲。地球上最大的动物生活在南大洋附近的海域，而在海洋温度最高的某些地方，我们可以找到不需要光便可生存的动物。海洋是一个神奇的世界，而我们对它的探索才刚刚开始
