| I will present methods to model the impact of very long ocean surface waves on ice shelves, primarily waves in the tsunami-infragravity regime. These wave induced vibrations have recently been measured in the Ross Ice Shelf in Antarctica, and there is strong evidence that ocean waves play a role in ice shelf calving (the process which leads to icebergs). I will demonstrate how methods developed to predict the hydroelastic motion of ships can be employed. The analysis is extended from the frequency domain to the time domain, and the resonant behaviour of the system is studied. I will also discuss various interesting mathematical features of this problem. |
