Time-Dependent Modelling of the Wave-Induced Vibration of Ice Shelves
This work presents an investigation of ice shelf vibration using a model based on shallow water approximation. The study focused on the effect of changes in the draft on the vibration of the ice shelf and presents both time-domain and frequency-domain results. The model used a radiation condition fo...

This work presents an investigation of ice shelf vibration using a model based on shallow water approximation.
