Disminución del espesor del casquete glaciar de la isla Livingston

Abstract

New evidences support that areal retreat of Livingston Island ice-cap (South Shetland Islands) since 1956, is accompanied by a marked ice thinning. Field observations, aerial photographic measures, topographic profiles and elevations measured by electronic geodimeter have been performed in several localities and indicate a 15 to 20 m thinning. Data collected in the last three years suggest that thinning rate may be slightly increasing
