AIR-ICE-OCEAN MOMENTUM EXCHANGE .1. ENERGY-TRANSFER BETWEEN WAVES ANDICE FLOES

The energy exchange between ocean surface waves and ice floes in the m arginal ice zone (MIZ) involves the scattering and attenuation of wave energy and the excitation of oscillation modes of the ice flees, as o pen ocean waves propagate into the MIZ. Heave, pitch, and roll modes o f oscillation are linked to estimation of wave scattering and attenuat ion. A model is presented for wave attenuation and compared to measure ments from the Marginal Ice Zone Experiments in the Greenland Sea, as reported by Wadhams et al.
