Bamber, J.L. & A. Rivera (2007) : "A review of remote sensing methods for glacier mass balance determination" Global and Planetary Change, 59, 138-148.

Airborne and satellite remote sensing is the only practical approach for deriving a wide area, regional assessment of glacier mass balance. A number of remote sensing approaches are possible for inferring the mass balance from some sort of proxy estimate. Here, we review the key methods relevant,...

High thinning rates (up to -4.0±0.97 m/a) have been measured at Campo de Hielo Patagónico Norte (CHN) or Northern Patagonia Icefield, Chile between 1975 and 2001. Results have been obtained by comparing a Digital Elevation Model (DEM) derived from regular cartography compiled by Instituto Geográ...

Woodward (2006) : "Exploration of Ellsworth Subglacial Lake: a concept paper on the development, organisation and execution of an experiment to explore, measure and sample the environment of a West Antarctic subglacial lake" Reviews in Environmental Science and Biotechnology, doi: 10.1007/s11157 - 006 - 9109-9, .

Antarctic subglacial lakes have, over the past few years, been hypothesised to house unique forms of life and hold detailed sedimentary records of past climate change. Testing this hypothesis requires in situ examinations. The direct measurement of subglacial lakes has been considered ever since...


Schwikowski, M.S .Brütsch, G. Casassa & A. Rivera (2006) : "A potential high-elevation ice core site at the Southern Patagonian Icefield" Annals of Glaciology, 43, 8 - 13.

The Patagonia icefields constitute a unique location in the Southern Hemisphere for obtaining non-polar paleo-records from ice cores south of 45° S. Nevertheless, no ice-core record with meaningful paleoclimate information has yet been obtained from Patagonia. This deficiency is due to extremely...


Bolius, D., M. Schwikowski, B. Rufibach, T. Jenk, G. Casassa and A.Rivera (2006) : "A first shallow firn core record from La Ollada Glacier on Cerro Mercedario in the Central Argentinean Andes" Annals of Glaciology, 43, 14 - 22.

In January 2003, shallow firn cores were recovered from Glaciar Esmeralda on Cerro del Plomo (33°14' S, 70°13' W; 5300ma.s.l.), central Chile, and from Glaciar La Ollada on Cerro Mercedario (31°58' S, 70°07'W; 6070ma.s.l.), Argentina, in order to find a suitable archive for paleoclimate reconstru...

Southern South America (SSA), i.e. south of 30°S, comprises an estimated glacier area of ca. 27,500km² (Fig. 47.1), which represents ca. 89% of all Andean glaciers. The glaciers in the region show a generalized retreat and thinning (Naruse, this volume, Chapter 46). In spite of their importance ...
