冰流模式和海洋环流模式两者之间的耦合，可以模拟海洋环境变化对冰盖稳定性的潜在影响，减小对冰盖物质平衡长期预测的不确定性。然而迄今为止，冰流模式和海洋环流模式两者之间的耦合大多侧重关注冰架作用下的海洋环流特征，忽视了冰架自身演化中的关键过程。本项目拟将先进的冰流模式（full-Stokes或者高阶近似的冰盖动力学模式）与海洋环流模式进行耦合，采用自适应网格技术极大降低计算量，采用反问题方法反演着地冰底部边界条件，模拟和研究着地冰与冰架之间、冰架与海洋之间的相互作用以及接地线动力学等关键过程，揭示冰架与海洋相互作用对冰盖长期物质平衡及其稳定性的影响，探索着地冰-冰架系统对海洋环境变化的响应和反馈，并将冰流-海洋耦合模式应用在南极的冰架上，通过模拟再现近年来观测的冰架动态变化，并预测在百年尺度上着地冰-冰架系统对海平面的贡献。

The coupling between ice flow model and ocean circulation model can estimate the potential impact of ocean environment change on the stability of ice sheet, and decrease the uncertainty of long-term prediction of ice sheet mass balance. So far, most of the couplings between ice flow model and ocean circulation model pay attention to the ocean circulation feature under the ice shelf forcing and ignore the key process in the ice shelf evolution. We want to couple the state-of-the-art ice flow model (full-Stokes model or high order model) with ocean circulation model, use adaptive mesh technique to decrease greatly the computation cost, and discover the basal boundary condition of grounded ice by inverse method, so that to model and study the interaction between grounded ice and ice shelf, the interaction between ice shelf and ocean and grounding line evolution, to display the impact of ice shelf-ocean interaction on ice sheet mass balance and its stability over long timescale, to investigate the response and feedback of grounded ice-ice shelf to ocean environment change, then we apply this coupled ice-ocean model to some Antarctic ice shelves, to model the their dynamic change in the past few years and predict their contribution to sea level rise in this century.
