研究了长周期海浪与冰架耦合的可能性。冰架采用厚弹性板模型，并与更简单的薄板模型进行比较。通过完全求解控制此类系统的速度势的方程来计算正常入射的单频海浪在冰架上产生的应变。在没有对冰架进行测量的情况下，现有的冰舌长周期应变测量可用于估计开放水域中所需的入射振幅，以引起观测到的振荡。研究发现，所需的海平面高度表明海浪驱动是观测到的振荡的一种合理的强迫机制。
The possibility of long-period ocean waves coupling to an ice shelf is investigated. A thick elastic plate model is used for the ice shelf with comparisons made to the simpler thin-plate model. The strain set up on the ice shelf by a normally incident single frequency ocean wave is calculated by completely solving the equations governing the velocity potential for such a system. In the absence of measurements on an ice shelf, existing measurements of long-period strain on an ice tongue are used to estimate the required incident amplitude in the open water to induce the observed oscillations. It is found that the height of seas required indicates that ocean wave driving is a plausible forcing mechanism for observed oscillations.
