The symposium will provide a forum for the presentation and discussion of current results of original research in the remote sensing of physical and biological phenomena and processes in the terrestrial and marine polar regions. The first two symposia, held in 1990 and 1992, pointed out that satellite and airborne remote sensing systems are one of the most valuable sources of environmental data for the study of the polar regions. Since then the successful launching of the ERS-1 and JERS-1 satellites is beginning to provide a massive amount of synthetic aperture radar (SAR) data of the polar regions through the Alaska SAR Facility, located on the campus of the University of Alaska, and has greatly expanded the scope of processes that can be studied remotely. ***
