Ice Sheet Modeling based on ISSM

Abstract

Various climate forcing scenarios have some impacts on the acceleration of ice shelf velocity (SMB < 5%, floating ice melting rate less than 5%, ice front retreat less than 13%, while the changes in sea level equivalent is insignificant. It is presumed that the existence of subglacial ridge near ice fall and the narrow width of Drygalski Ice Tongue make the David Galcier stable. Additional sensitivity experiments are underway.
