Glasser, N.F., K.N. Jansson, S. Harrison, A. Rivera (2005) : "Geomorphological evidence for variations of the North Patagonian Icefield during the Holocene" Geomorphology, 71, 263-277.

Elucidating the timing and extent of former glacier fluctuations is important because of the palaeoclimatic inferences that can be drawn from such studies. Here we present new geomorphological evidence of the patterns of glacier behaviour around the North Patagonian Icefield during the Holocene. ...


Rignot, E., G. Casassa, S. Gogineni, P. Kanagaratnam, W. Krabill, H. Pritchard, A. Rivera, R. Thomas, J. Turner, and D. Vaughan (2005) : "Recent ice loss from the Fleming and other glaciers, Wordie Bay, West Antarctic Peninsula" Geophysical Research Letters, , L07502, doi:10.1029/2004GL021947.

Satellite radar interferometry data from 1995 to 2004, and airborne ice thickness data from 2002, reveal that the glaciers flowing into former Wordie Ice Shelf, West Antarctic Peninsula, discharge 6.8 ± 0.3 km³/yr of ice, which is 84 ± 30 percent larger than a snow accumulation of 3.7 ± 0.8 km³/y...

Hielo Patagónico Sur (HPS; southern Patagonia icefield) is the largest temperate ice mass at mid-latitudes in the Southern Hemisphere. With few exceptions, the glaciers in this region have been retreating during the last 50 years. Based on field data, vertical aerial photographs and satellite ima...

Ice-capped volcanoes of the Chilean Lake District have shown significant glacier retreat during recent decades, probably in response to tropospheric warming and precipitation decrease. Volcán Mocho-Choshuenco (39°55?S, 72°02?W) is one of the main active volcanoes in this part of the country. A...

The variations and dynamics of the southern edge of Fuchs Ice Piedmont, Adelaide Island (67845' 09' S, 68855' 04' W), Antarctic Peninsula, are presented. The snow-covered surface of the glacier has been used since the 1960s for landing aeroplanes in support of British, and more recently Chilean, ...


Rivera, A (2004) : "Mass balance investigations at Glaciar Chico, Southern Patagonia Icefield Chile" PhD thesis, University of Bristol, UK, 303 pp.

The Southern Patagonia Icefield (SPI) is the largest temperate ice mass at mid-latitudes in the Southern Hemisphere, and an area where most glaciers have been retreating during the last 50 years. Based on field data, vertical aerial photographs and satellite images, the changes experienced by Gla...
