壮丽的景观——南极冰山

    在南极周围的海洋中,漂浮着数以万计的冰山,大约可达22万座,平均每座冰山重10万吨。体积之大,数量之多,远远超乎人们的想象。1956年,美国人观测到一座竿见的大冰山,长333千米,宽96千米。这样巨大的冰山,难道不是移动的岛屿吗?实际上它的面积远远超过了大洋中的一些小岛。冰山,在海上看起来似乎是静止的,实际上它在移动,随着海流的方向移动。一般寿命可以维持10年左右。而北冰洋的冰山平均寿命仅有2~4年。

    南极周围漂泊的大量冰山,虽然美丽壮观,给大洋增色不少,但是对于航行在海上的船只来说,冰山始终是可怕的威胁。还记得1912年,当时最豪华的泰坦尼克号客轮首航,就是因撞上冰山而沉没的。电影中的镜头给我们留下了深刻的印象。另一方面南极大陆的冰,约占世界冰总体积的90%以上,是人类可以利用的巨大的固体水库。如果能把这些冰运到沙漠地区可解决那里的缺水问题。目前,西亚国家,如沙特阿拉伯,正在研究把南极的冰运回本国,以解决缺水问题。美国、澳大利亚、智利等国也在研究利用南极淡水资源的问题。
