Abstract :
Using SAR imagery, the spatial variability of the wave and current field has been estimated through spectral analysis and wave modelling. SAR spectra of waves-in-ice in the Bering Sea were computed from C-band ERS-1 SAR images for the study of wave evolution in the marginal ice zone (MIZ). Based on the change of wavelength and energy, two kinds of ice near the ice edge can be identified. Wave attenuation in the MIZ has also been estimated and compared reasonably well with the wave model. The change of SAR backscatters of new ice and compact ice is consistent with the change of wave energy
