The majority of glaciers in the Chilean Lake District (38º - 42ºS) have experienced shrinking and ice thinning during recent decades, presumably in response to climatic changes as observed at nearby meteorological stations. One of these glaciers is the southeastern basin of Volcán Mocho-Choshuenc...

Subglacial Lake Ellsworth (SLE) was identified using reconnaissance data collected in the 1970s, here we present more detailed surveys. SLE lies beneath 3.2 km of ice in a subglacial valley in West Antarctica. It has an area of only 18 km2, is dissimilar to the large tectonically-controlled lakes...

The energy balance of bare snow and tephra-covered ice near the glacier equilibrium line elevation on Villarrica Volcano, southern Chile, was investigated during 2004 and 2005, combining meteorological, surface temperature and ablation measurements with energy balance modelling. A tephra...

The first airborne laser altimetry measurements of a glacier in South America are presented. Data were collected in November of 2001 over Glaciar Tyndall, Torres del Paine National Park, Chilean Patagonia, onboard a Twin Otter airplane of the Chilean Air Force. A laser scanner with a rotating pol...


Casassa, G., A. Rivera, W. Haeberlib, G. Jones, G. Kaser, P. Ribstein & C. Schneider (2007) : "Editorial. Current status of Andean glaciers" Global and Planetary Change, 59, 1-9.

Glaciers are sensitive indicators of climate variability and in turn they can also affect climate by means of complex feedback mechanisms. After the Little Ice Age (LIA), a cold climate period reported mainly for the Northern Hemisphere that culminated in mid-late 19th century, glaciers started r...


Bown, F. & A. Rivera (2007) : "Climate changes and glacier responses during recent decades in the Chilean Lake District" Global and Planetary Change, 59, 79-86.

Atmospheric temperatures measured at the Chilean Lake District (38° - 42°S) showed contrasting trends during the second half of the 20th century. The surface cooling detected at several meteorological stations ranged from - 0.014 to - 0.021 °C a-1, whilst upper troposphere (850 - 300 gpm) reco...
