The applications of NOAA and Landsat imagery for monitoring and mapping sea-ice breakup and freezeup are discussed. In particular, the results of studies using imagery collected over Canadian Arctic seas during July to November, 1975 through 1977, are presented in three maps. The maps indicate important features of areal and temporal variations in processes of sea-ice deformation and growth. This study has shown that much information concerning sea-ice breakup and freezeup can be obtained by combined use of NOAA and Landsat imagery. Moreover, it is suggested that satellite imagery could be used in obtaining long-term sea-ice statistical data which are necessary for climatological modeling and future planning of navigation as well as offshore gas and oil exploration in Arctic Canada.
