Recent and imminent calving events do little to impair Amery ice shelf’s stability

摘要

Accounting for about half of mass loss in Antarctic,glacier calving is an important ablation process for the ice sheet(Liu et al.,2015).Thanks to the revolutionized era of satellite remote sensing,the 21st century witnessed dozens of prominent calving events.However,calving could occur as a natural behavior of the glacier to maintain itself in a steady state,rather than forced by external environment factors.
