PI打算继续两条科学路线 目前正在调查中。 第一个涉及 冰盖稳定性作为底流函数的研究 变形床，边缘熔融引起的不稳定 引发冰盖崩塌 现场和建模工作支持 触发机制的想法，如果正确，也可以解释 与冰有关的沉积物沉积模式 冰川运动 此外，PI将继续在基础物理方面的工作， 冰川冰的变化及其对更广泛的 古气候学领域。
英文摘要
The PI intends to continue to two lines of scientific inquiry currently under investigation. The first involves studies in ice sheet stability as a function of basal flow of a deforming bed, where instability caused by marginal melting triggers ice sheet collapse. Field and modeling work support the idea of a triggering mechanism, and if correct, can also explain the patterns of ice- related, sediment deposition associated with glacial movement. In addition the PI will continue work in the basic physics of glacial ice, its transformation and implication to the broader field of paleoclimatology.
