In the context of global climate change, the investigation of ice-shelf systems has become critically important to assess ice-sheet stability.Conventional measurement-based approaches to the analysis of ice-sheet motion and evolution are limited.However, ice-sheet modeling provides a valuable and effective tool to study the dynamics and evolution of ice shelves.Here, the Lambert-Amery ice shelf system, the largest glacier system in East Antarctica and an important focus of research into the mass balance and stability of the East Antarctica Ice Sheet, is studied using the PISM ice sheet model.We simulate the surface ice velocity field of this glacier system and compare the model results with actual measurements from remote sensing.The comparison indicates that the model performs well to predict the velocity field across the Amery Ice Shelf.We further discuss the prospect of applying ice sheet modeling to research into the evolution of ice sheets and ice caps.
