南極冰蓋

南極冰蓋是地球上的兩個極地冰蓋英語Polar ice cap之一。它覆蓋了南極大陸的大約98%(1400萬平方公里)的面積,體積是2650萬立方公里,是地球上面積最大的單一冰塊[1]。一立方公里的冰大約有一公噸重,這意味着南極冰蓋的重量為26,500,000公噸。地球上所有淡水的大約61%位於南極洲的冰層中,若全部融化,相當於海平面上升大約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.
