AbstractTo date, automated sea?ice motion tracking algorithms for synthetic aperture radar data have been developed and tested using SEASAT imagery acquired over the Beaufort Sea where the sea ice is characticed by large multi?year ice floes with conspicuous structural features. The LIMEX experiments conducted in March of 1987 and 1989 off the East Coast of Canada, provide an opportunity to evaluate the techniques in a region where the floes are small and in some instances featureless. Processing for an image pair from each of the LIMEX experiments shows that monitoring the ice movement was possible and the best results were achieved using a finer pixel resolution than selected in the Beaufort Sea studies. When ice floes were present, the algorithm tracked the movement of the individual floes. In areas with open leads surrounded by subresolution floes, the algorithm tracked the movement or deformation of the open lead boundaries and not the individual floes.
