Abstract
Ice-free areas within the Northern Antarctic Peninsula
region are of interest for studying changes occurring to
surface covers, including those related to glacial coverage,
raised beach deposits and periglacial processes and
permafrost. The objective of this work is to map the main
surface covers within ice-free areas of King George Island,
the largest island of the South Shetlands archipelago, using
fully polarimetric RADARSAT-2 SAR data.
Surface covers such as rock outcrops and glacial till, stone
fields, patterned ground, and sand and gravel deposits form
the most representative classes and account for 84 km2 of
the ice-free areas on the island. A distribution of complex
geomorphological features and landforms was obtained,
being some of them considered indicators of periglacial
processes and presence of permafrost.
