A unique natural laboratory for environmental and climate change studies. CASASSA, G., F. SEPÚLVEDA & R. SINCLAIR (Eds.) Kluwer Academic/Plenum Publishers, New York, pp. 101-115.

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 use...


Lythe, M., Vaughan, D., and the BEDMAP Consortium (2001) : "BEDMAP: A new ice thickness and subglacial topographic model of Antarctica" Journal of Geophysical Research, 106(B6): 11335-11351.

Measurements of ice thickness on the Antarctic ice sheet collected during surveys undertaken over the past 50 years have been brought together into a single database. From these data, a seamless suite of digital topographic models have been compiled for Antarctica and its surrounding ocean. This ...


Casassa, G. & Rivera, A. (2001) : "Campo de Hielo Sur: Su historia" Anales del Instituto de la Patagonia, Serie Ciencias Humanas, 29:29-78.

Se presenta una síntesis de la historia limítrofe del Campo de Hielo Patagónico Sur, indicando las líneas fronterizas sostenidas por Chile y Argentina luego del laudo arbitral de 1902, la traza poligonal de 1991 y la traza finalmente acordada en 1998 por ambos países. El trabajo incluye una recop...


Rivera, A., Casassa. G., Acuña. C (2001) : "Mediciones de espesor en glaciares de Chile centro-sur" Revista Investigaciones Geográficas, 35: 67-100.

The results of ice thickness measurements carried out in Chile (30-41°C) during recent years are presented. The information was obteined by means of radar in five glaciers. In all of therm, the radar signals were slightly attenuated allowing penetration of the ice to the bedrock. This means that ...


Casassa, G., Rivera, A. & Carrasco, J. (2000) : "Glacier variations in the Southern Patagonia Icefield and their Relation with Climate" In: Sixth International Conference on Southern Hemisphere Meteorology and Oceanography, pp. 312-313.

Glacier variations during the past 50 years have been determined for the major 48 outlet glaciers of the Southern Patagonia Icefield, southern South America. Most glaciers exhibit a clear retreat, a few are in near-equilibrium and one has been advancing. These variations are analyzed in relation ...
