Bown, F., A. Rivera & C. Acuña (2008) : "Recent glaciers variations at the Aconcagua basin, central Chilean Andes" Annals of Glaciology, 48, 43-48.

The majority of glaciers in central Chile have receded in recent decades, from >50m to only a few meters per year, mainly in response to an increase in the 0°C isotherm altitude. The Aconcagua river basin (33° S) is one of the major glaciated basins in central Chile, with 121km2 of ice in ...

Darkening Peaks: Glacier Retreat, Science and Society, University of California Press, USA, 126-135.

The Central Dry Andes form a high mountain barrier dividing Chile and Argentina between around latitude 31º and 35º S. They run north - south, reaching the highest elevations in the Southern Hemisphere: Aconcagua is 6,954 m a.s.l., while many other peaks rise over 6,000 m. Their slopes descend ab...

Part I: Global overview and outlook. Part II: Glacier changes around the world" In: UNEP: Global outlook for ice & snow, 115 - 152.

Glaciers and ice caps reached their Holocene (the past 10 000 years) maximum extent in most mountain ranges throughout the world towards the end of the Little Ice Age, between the 17th and mid-19th century. Over the past hundred years a trend of dramatic shrinking is apparent over the entire glob...

Detection of crevasses is critical for safe travelling on glaciers. Here we present the use of a Ground Penetrating Radar (GPR) for crevasse detection. Experiments were made in temperate ice on Glaciar Mocho, Volcán Mocho - Choshuenco, southern Chile (39°25' S) and in cold ice in East Antarctica ...


Bown, F., A. Rivera, C. Acuña & G. Casassa (2007) : "Recent glacier mass balance calculations at Volcán Mocho-Choshuenco (40ºS), Chilean Lake District" IAHS Publ, 318, 143-152.

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...
