We have study the coupled ocean-ice dynamics in the marginal ice zone (MIZ) in the Bering Sea. First, sea ice motion and deformation have been analyzed using the high resolution synthetic aperture radar (SAR) images. Segmentation techniques and statistical methods have been used to derive ice motion and deformation maps. These techniques involve a dynamic local thresholding (DLT), which allows separation of sea ice into different classes of thickness and type. We observed two ice motion characteristics with one consisting of a translation and a rotation at scale larger than about 10km/day and the other being ice field deformations at spatial scale less than about 5km. The results were compared with low-resolution values derived from Advanced Microwave Scanning Radiometer for EOS (AMSR-E) data for consistency. In addition, we implemented a two-dimensional coupled ice-ocean model (with wave effects incorporated) and made a direct comparison between the model and remote sensing results. Preliminary results on the effects of waves on ice cover were also obtained.
