海洋冰盖的不稳定性对于南极洲对未来海平面上升的贡献尤为重要。过去对这种不稳定性的研究主要集中在冰盖下游冰架的支撑作用上。然而,冰盖所处的河床地形很可能对冰盖的演变起着根本性的作用。在这里,我们研究这个角色系统的平行冰盖模式。
英文摘要
The marine ice sheet instability is particularly important for the Antarctic contribution to future sea-level rise. Past investigations of this instability have focussed on the buttressing role of the ice shelves downstream of the ice sheet. It is however likely that the bed topography on which the ice sheet rests has a fundamental role for the evolution of the ice sheet. Here we investigate this role systematically with the Parallel Ice Sheet Model.
