南極冰蓋
南极冰盖是地球上的两个极地冰盖之一。它覆盖了南极大陆的大约98%（1400万平方公里）的面積，體積是2650万立方公里，是地球上面積最大的单一冰块[1]。一立方公里的冰大约有一公吨重，这意味着南極冰蓋的重量为26,500,000公吨。地球上所有淡水的大约61%位於南极洲的冰层中，若全部融化，相当于海平面上升大约58米[2]。

Using data largely collected during the 1970s, Drewry et al. (1992), estimated the potential sea-level contribution of the Antarctic ice sheets to be in the range of 60-72 m; for Bedmap1 this value was 57 m (Lythe et al., 2001), and for Bedmap2 it is 58 m.
