Research Abstract

A numerical ice shelf model is developed in order to understand/simulate response of ice-sheets on climate variation. An ice-sheet model is used to evaluate the potential contribution of ice-shelf grounding to the ice-sheet volume and it is found to be an essential to understand the variation of ice-shelf to understand the whole Antarctic ice-sheet. After discussing influence of errors due to finite-precision numerics on ice-sheet evolution, the ice-shelf model is designed to reduce such numerical errors, and tested under various configuration.
