Rivera, A.; Bown, F.; Wendt A. and C. Bravo (2012) : "Recent glacier changes in southern Chile and in the Antarctic Peninsula" Anales Instituto Patagonia (Chile), 40(1), 39-44.

In historical times, glaciers in Southern Chile have experienced a significant area reduction mainly in response to ongoing atmospheric warming. Here we present some of the research that has been done by Centro de Estudios Científicos, CECs, Valdivia, during recent years. This research has been ...


Brock, B., F. Burger, A. Rivera & A. Montecinos (2012) : "A fifty year record of winter glacier melt events in southern Chile, 38º-42ºS" Environmental Research letters, doi:10.1088/1748-9326/7/4/045403.

Little is known about the frequency and potential mass balance impact of winter glacier melt events. In this study, daily atmospheric temperature soundings from the Puerto Montt radiosonde (41.43ºS) are used to reconstruct winter melting events at the glacier equilibrium line altitude in the 38...

A time-series composed of 156 ASTER derived Digital Elevation Models (DEMs) and a radar-penetration-bias corrected version of the Shuttle Radar Topography Mission (SRTM) DEM is used to derive ice surface height and volume changes at the Southern Patagonian Ice Field (SPI) in southern South Americ...


Rivera, A., M. Koppes, C. Bravo, and J. Aravena (2012) : "Little Ice Age advance and retreat of Glaciar Jorge Montt, Chilean Patagonia." Climate of the Past, 8, 403-414..

Glaciar Jorge Montt (48°20′ S , 73°30′ W), one of the main tidewater glaciers of the Southern Patagonian Icefield (SPI), has experienced the greatest terminal retreat observed in Patagonia during the past century, with a recession of 19.5 km between 1898 and 2011. This retreat has revealed trees ...


Rivera, A., Bown, F., Carrión, D., Zenteno, P. (2012) : "Glacier response to recent volcanic activity in Southern Chile." Environmental Research Letters, , 7, doi:10.1088/1748-9326/7/014036..

Glaciers in Southern Chile (39–43°S) are characterized by frontal retreats and area losses in response to the ongoing climatic changes at a timescale of decades. Superimposed on these longer-term trends, volcanic activity is thought to impact glaciers in variable ways. Debris–ash covered Glaciar ...


Rivera, A.; Corripio, J.; Bravo, C. & Cisternas, S. (2012) : "Glaciar Jorge Montt (Chilean Patagonia) dynamics derived from photos obtained by fixed cameras and satellite image feature tracking." Annals of Glaciology, 53(60), 147-155.

Tidewater calving glaciers can undergo large fluctuations not necessarily in direct response to climate, but rather owing to complex ice–water interactions at the glacier termini. One example of this process in Chilean Patagonia is Glaciar Jorge Montt, where two cameras were installed in February...
