Geomorphological mapping in the Antarctic Peninsula region applying single and multipolarization RADARSAT-2 data
RADARSAT-2 data in the ultra-fine and fine quad polarization mode was evaluated to identify morpho-structural, periglacial, and other geomorphological features within the Antarctic Peninsula region. The study was carried out within Byers Peninsula, the largest ice-free area on the South Shetland Isl...
