Durand M.; Rivera A.; Geremia-Nievinski F.; Lenzano M.G.; Galera Monico J.F.; Paredes P. and Lenzano L. (2019) : "GPS reflectometry study detecting snow height changes in the Southern Patagonia Icefield" Cold Regions Science and Technology, Volume 166, DOI: 10.1016/j.coldregions.2019.102840.

Southern Patagonia Icefield (SPI) glaciers have been retreating and shrinking at high rates in recent decades, significantly contributing to sea level rise. In spite of the importance of the SPI, very little is known about its mass balance apart from models lacking in situ validation, such as sno...

Hace 62 años que Louis Lliboutry publicó y glaciares de Chile. Fundamentos de glaciología Nieves, texto insigne que sigue siendo un tratado imprescindible en habla castellana para todos aquellos interesados en glaciología teórica y la exploración de los Andes. Este texto surgió al alero de la Uni...


Rivera, A. (2019) : "Desafíos glaciológicos del Campo de Hielo Sur" En Turrel, M. El hombre que descifró los glaciares Luis Lliboutry. Aguas Andinas, pp. 224-231.

El Campo de Hielo Sur (CHS) es un conjunto de glaciares que se extiende desde los 48.3° a los 51.6° de latitud sur, territorio que es compartido por Chile y Argentina, constituyéndose en la mayor masa de hielo temperado del hemisferio sur, con un área que totaliza en la actualidad 12,636 km² dis...


Reinthaler J.; Paul F.; Granados H.; Rivera A. & Huggel C. (2019) : "Area changes of glaciers on active volcanoes in Latin America between 1986 and 2015 observed from multi-temporal satellite imagery" Journal of Glaciology, doi.org/10.1017/jog.2019.30.

Glaciers on active volcanoes are subject to changes in both climate fluctuations and volcanic activity. Whereas many studies analysed changes on individual volcanoes, this study presents for the first time a comparison of glacier changes on active volcanoes on a continental scale. Glacier areas w...


Millan R.; Rignot E.; Rivera A.; Martineau V.; Mouginot J.; Zamora R.; Uribe J.; Lenzano G.; De Fleurian B.; Li X.; Gim Y. and Kirchner D. (2019) : "Ice Thickness and Bed Elevation of the Northern and Southern Patagonian Icefields" Geophysical Research Letters, doi.org/10.1029/2019GL082485.

The Northern and Southern Patagonian Icefields are the largest ice masses in the Southern Hemisphere outside Antarctica, but their ice volume and bed topography are poorly known. Here, we combine airborne gravity data collected in 2012 and 2016, with radar data from the Warm Ice Experiment Sounde...


Bravo C.; Quincey D.J.; Ross A.N.; Rivera A.; Brock B.; Miles E. and Silva A. (2019) : "Air Temperature Characteristics, Distribution, and Impact on Modeled Ablation for the South Patagonia Icefield" Journal of Geophysical Research Atmospheres, DOI: 10.1029/2018JD028857.

The glaciers of Patagonia are the largest in South America and are shrinking rapidly, raising concerns about their contribution to sea?level-rise in the face of ongoing climatic change. However, modelling studies forecasting future glacier recession are limited by the scarcity of measured on?glac...
