Abstract

It has been demonstrated that ice rheology may depend strongly on the ice concentration, thickness distribution, and the rate of deformation. To study ice rheology, the kinematics of the ice cover must first be determined. In this study, satellite imagery obtained from the NOAA AVHRR instrument is utilized to investigate the velocity field and the rate of deformation at different scales. The study region is the Sea of the Okhotsk. The results indicate that although the general trend of velocity field remains similar between scales, details of the velocity field are observed to be sensitive to scale. The derived strain-rate fields also show some dependence on the scale of observation. These results indicate that constitutive laws could be scale sensitive.
