Sea ice floes dissipate the energy of steep ocean waves
Article first published online: 25 OCT 2015 A laboratory experimental model of an incident ocean wave interacting with an ice floe is used to validate the canonical, solitary floe version of contemporary theoretical models of wave attenuation in the ice-covered ocean. Amplitudes of waves transmitted...
