Purpose. The aim of the study is to investigate the spatial and temporal variability of drifting ice field edge and the features of eddy generation in the marginal ice zone (MIZ) in Fram Strait and near Svalbard during the warm period in 2007. Methods and Results. Satellite radar images of Envisat ASAR for June - September 2007 were used to fix the position of drifting ice field boundary and to reveal the surface manifestations of eddy generations in the MIZ. It is established that during the upper mentioned period, the ice - water boundary experienced unequal displacements along its entire length, and that a total range of the ice edge movements was 30-220 km. At different wind conditions, the ice edge motion was accompanied by the formation of ice filaments and eddies, the maximum number of which was recorded in June. The data analysis allowed us to identify more than 2000 pronounced MIZ eddies in which the structures with a cyclonic type of rotation were evidently predominant (78%)...
