Abstract

Abstract

Total sea ice deformation rates are produced based on RADARSAT Geophysical Processer System (RGPS) dataset (divergence, vorticity and shear) in this paper, as well as the probability distribution of samples whose value of total sea ice deformation rate are lager than 0.01/d in the Arctic Ocean. The results show that mean value of total deformation rates (TDR) of whole dataset (from November 1996 to April 2008) is 0.020 4/d. There are 45.89% samples whose value of TDR are lager than 0.01/d.TDR in coast area are larger than those near North Polar. There are statistically significant differences in the average TDR between summer and winter. Both average TDR and occurrence probabilities of samples whose value of TDR are lager than 0.01/d in summer are larger than those in winter. Where probability of occurrence in summer is 59% which has 18% more than that in winter. It may be lead by the amplify effect of sea ice melting-broken-easier melting-easier broken in summer, and than it makes the Arctic sea ice TDR larger than in winter.
