“…Fractures and lineaments analysis have been determined using field data measurements and aerial photographs and satellite data interpretation (e.g. Mink et al, 2015). By studying relatively large ice-free areas, like Byers Peninsula (60.6 km 2 ), the largest ice-free area in the region, relationships between drainage streams development and the fractures network have been identified, as well as its relation with the time and mode of deglaciation (Mink et al, 2014).…”

“…These rocks show an increase in metamorphism from NE to SW, with zones oriented NW‐SE that in the studied western part of the island correspond to serpentine, almandine, green amphibole, and biotite metamorphic zones (Trouw et al, ). These materials are affected by ductile and brittle deformations, signs of recent uplift (e.g., Galindo‐Zaldívar, Maestro, López‐Martínez, & Sanz de Galdeano, ; Mink et al, ).…”

International audienceSatellite-borne Synthetic Aperture Radar (SAR) has been used for characterizing and mapping in two relevant ice-free areas in the South Shetland Islands. The objective has been to identify and characterize land surface covers that mainly include periglacial and glacial landforms, using fully polarimetric SAR C band RADARSAT-2 data, on Fildes Peninsula that forms part of King George Island, and Ardley Island. Polarimetric parameters obtained from the SAR data, a selection of field based training and validation sites and a supervised classification approach, using the support vector machine were chosen to determine the spatial distribution of the different landforms. Eight periglacial and glacial landforms were characterized according to their scattering mechanisms using a set of 48 polarimetric parameters. The mapping of the most representative surface covers included colluvial deposits, stone fields and pavements, patterned grounds, glacial till and rock outcrops, lakes and glacier ice. The overall accuracy of the results was estimated at 81%, a significant value when mapping areas that are within isolated regions where access is limited. Periglacial surface covers such as stone fields and pavements occupy 25% and patterned grounds over 20% of the ice-free areas. These are results that form the basis for an extensive monitoring of the ice-free areas throughout the northern Antarctic Peninsula region
