This research area addresses the fundamental question of nonlinear wave-ice interaction under solid ice focusing on nonlinear wave propagation and dispersion of waves. The objective is to verify if nonlinearity takes place under solid ice and if this can lead to intense wave events far away from the ice edge in order to provide an explanation for observed real-world ice break-ups. Thereby, nonlinear wave-ice interaction as well as the impact of the solid ice characteristics on this interaction will be investigated. The investigations comprise numerical simulations accompanied by experiments. Special nonlinear wave groups and typical swell conditions in the vicinity of ice covers will be investigated. In addition, typical swell conditions will be investigated in order to identify nonlinear wave grouping effects and ice breakup mechanism under more realistic conditions.
