Interactions between irregular wave fields and sea ice: A physical model for wave attenuation and ice breakup in an ice tank
Irregular, unidirectional surface water waves incident on model ice in an ice tank are used as a physical model of ocean surface wave interactions with sea ice. Results are given for an experiment consisting of three tests, starting with a continuous ice cover and in which the incident wave steepnes...
