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...

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...

A synthesis of glaciological studies carried out in Chile during recent decades is presented, including inventories and records of glacier variations, fluctuations of which are related to regional climate change and their contribution to eustatic sea-level rise. Based upon satellite imagery, aer...

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...
