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 ...


Rivera, A., Casassa, G., Acuña, C. & Vieira, R. (2000) : "Recent glacier variations and snow line changes in central Chile" In: Sixth International Conference on Southern Hemisphere Meteorology and Oceanography, pp. 274-275.

Glaciers in the Chilean central Andes (28° - 41° S) have shown a signigicant frontal retreat during the last 4 decades, additionally, they present an important reduction of their surfaces. This process is believed to be a clear response to the temperature increase observed at weather stations hol...


Carrasco, J., Casassa, G. & Rivera, A. (2000) : "A warm event at Patriot Hills, Antarctica: An ENSO related phenomen?" In: Sixth International Conference on Southern Hemisphere Meteorology and Oceanography, pp. 240-241.

Patriot Hills located at the end of the Ellsworth Mountains, in the interior of West Antarctica. It is a smal hill about 400m aboce the ice/snow surface and 8km long, with the highest summit of 1246 m.a.s.l. More than a thousand kilometers separates Patriot Hills from the nearest open southern oc...
