Resumen / Abstract.

The first detailed ice thickness measurements in the accumulation area of the Southern Patagonia Icefield have been obtained with a radio-echo sounding system, revealing a complex subglacial topography and internal reflection pattern. A ground-based digital impulse radar system at 2.5 MHz was used to obtain continuous profiles of the subglacial topography the system was mounted on sledges that were pulled by a snowmobile, allowing for coverage of extensive areas in short periods of time.
