Rivera, A. and G. Casassa (2004) : "Ice elevation, areal, and frontal changes of glaciers from National Park Torres del Paine, Southern Patagonia Icefiled" Artic, Antarctic and Alpine Research, 36(4), 379 - 389.

Ice elevation changes since 1975 and ice areal changes since 1945 of glaciers in the southeastern part of the Southern Patagonia Icefield (SPI) are presented. Comparison of digital elevation models, GPS, and optical survey data revealed high thinning rates for all the ablation areas of the glacie...


Rignot, E., Rivera, A. & Casassa, G. (2003) : "Contribution of the Patagonia Icefields of South America to Global Sea Level Rise" Science, 302: 434 - 437.

Digital elevation models of the Northern and Southern Patagonia Icefields of South America generated from the 2000 Shuttle Radar Topography Mission were compared with earlier cartography to estimate the volume change of the largest 63 glaciers. During the period 1968/1975 - 2000, these glaciers l...

A glacier inventory for península Cordova, isla Riesco, Chilean Patagonia (53º14' S,73º00' W), has been compiled based on stereoscopic interpretation of aerial photographs ofMarch and December 1984 and 1:100 000 topographicmaps.Three small icefields comprising 33 glacier outlets, in addition to 1...

The Southern Patagonia Icefield (SPI) is located at mid-latitudes in southern South America, which is dominated by the westerly regime and frontal systems. This results in a high frecuency of cloudy days (more than 70% of the time) and precipitation events. Analyses of air temperature and precipi...

In February 1999 a 36 m ice core reaching bedrock of the cerro Tapado summit glacier (5550m, 30°08'S, 69°55' W) was recovered in order to investigate the suitability of this glacier as paleoenvironmental an climate archive. Site selection was based on the assumption thas this area is strongly inf...

A unique natural laboratory for environmental and climate change studies. CASASSA, G., F. SEPÚLVEDA & R. SINCLAIR (Eds.) Kluwer Academic/Plenum Publishers, New York, pp. 67-83.

We present here a review of the current glaciological knowlegde of the Southern Patagonia Icefield (SPI). With an area of 13,000 km² and 48 major glaciers, the SPI is the largest ice mass in the Southern Hemisphere outside of Antarctica. The glacier inventory and recent glacier variations are pre...
