纪录片《冰冻星球》 第81期 履于薄冰（13）（在线收听）

99% of the Arctic's fresh water ice is in Greenland.

北极地区99%的淡水冰在格陵兰

It's a staggeringly big ice sheet,

这是块相当巨大的冰原

but it's just a drop in the ocean

但和南极比起来

compared to that at the southern end of our planet.

就只是沧海一粟了

In Antarctica, there is ten times more ice,

南极的冰比北极多十倍

by far the largest concentration of ice on Earth.

是目前地球上冰量最多的地方

Our exploration of the Antarctic

我们对于南极的探索

only began a little over 100 years ago.

始于一百多年前

The study of ice retreat here was unwittingly begun

关于冰山锐减的研究

on an expedition led by the great early explorer

始于早期伟大探索家欧内斯特·沙克尔顿

Ernest Shackleton.

领导的一次不为人知的探险

In 1916, after their expedition boat was crushed and sunk by ice,

1916年 考察船撞毁陷入冰川

Shackleton and two companions

沙克尔顿和他的两名同伴

set off to summon help in a tiny boat.

划了艘小船出去寻求援助

They sailed over 800 miles across the Southern Ocean

它们在南大洋航行了八百多英里

to the island of South Georgia, on the edge of the Antarctic.

到达了南极边缘的南乔治亚岛

Near starving and dressed in rags, the three men

饥肠辘辘 衣衫褴褛的三个人

walked across the ice sheet at the centre of the island,

穿越过岛中央的茫茫冰原

knowing there was a whaling base

他们知道

on the opposite coast where they could summon help.

可以向对面海岸的捕鲸队呼救
