Integrating rifts and swell in the mathematics of ice shelf disintegration

南极冰架解体有可能通过加速南极冰盖的融化和引发失控的冰盖不稳定而导致海平面迅速上升，这令人担忧。该项目的目的是在一个耦合的海洋-大陆架三维框架内建立一个膨胀引起的冰架振动的数学模型，重点是振动与断裂网络之间的相互作用，这些断裂网络在解体前覆盖着大陆架外缘。精确，有效的解决方案将通过融合强大的近似理论，并通过数值解验证。该模型将与最先进的数据相结合，以预测南极洲剩余冰架的趋势，并指出未来可能的解体。

Antarctic ice-shelf disintegrations have the alarming potential to cause rapid sea level rise, through accelerated discharge of the Antarctic Ice Sheet and initiating runaway Ice Sheet destabilisations. The project aims to develop a mathematical model of swell-induced ice-shelf vibrations in a coupled ocean–shelf 3D framework, focusing on interactions between vibrations and the rift networks that characterise outer shelf margins before disintegration. Accurate, efficient solutions will be developed by fusing powerful approximation theories, and validated by numerical solutions. The model will be combined with state-of-the-art data to predict trends in Antarctica’s remaining ice shelves and indicate potential future disintegrations.
