Surface velocities of Upsala glacier, Southern Patagonian Andes, estimated using cross-correlation satellite imagery: 2013-2014 period

ABSTRACT In this study we present surface velocities estimation for the Upsala glacier catchment, South Patagonian Ice Field (SPI) during the summer season of years 2013 (January-March) and 2014 (March-April), including the Bertacchi, Cono, and Murallón tributaries using satellite images from Advanc...
