Zamora R.; Uribe J.; Oberreuter J. and Rivera A. (2017) : "Ice thickness surveys of the Southern Patagonian Ice Field using a low frequency ice penetrating radar system" First international symposium on geoscience and remote sensing (GRSS-CHILE), DOI: 10.1109/GRSS-CHILE.2017.7996003.

An airborne low frequency radar system used to survey the ice thickness of the northern part of the Southern Patagonian Ice Field (SPI) is presented. The radar is an impulse system operating at a central frequency of 20 MHz. The system is controlled and operated from a helicopter cabin connected ...


Petlicki M. (2017) : "Inferring Subglacial Topography of the Emerald Icefalls (King George Island, Antarctica) from Ice Surface Terrestrial Laser Scanning" First international symposium on geoscience and remote sensing (GRSS-CHILE), DOI: 10.1109/GRSS-CHILE.2017.7996014.

Information about ice thickness and sub glacial topography is critical for ice dynamics modelling and, consequently, for better understanding of current response of glaciers to climatic forcing. While there is a great progress in measurements of glacial surface, ice thickness measurements have li...


Hernandez J.; Paredes P.; Carrión D. and Rivera A. (2017) : "Ice elevation changes surveyed with Airborne Laser Scanning Data" First international symposium on geoscience and remote sensing (GRSS-CHILE), DOI: 10.1109/GRSS-CHILE.2017.7996012.

Se presentan los cambios de elevación detectados en el periodo 2013–2016 de los glaciares Olivares Alfa y Beta, ubicados en la cuenca alta del Río Olivares (33°06'–33°14' S y los 70°10'–70°14' W), utilizando modelos digitales de elevación (MDE) generados a partir de datos láser (LiDAR). La ...


Cisternas S.; Bravo C. and Rivera A. (2017) : "Recent glacier area variations at Cerro O'Higgins (48°30'S, 73°10'W), Southern Patagonian Icefield" First international symposium on geoscience and remote sensing (GRSS-CHILE), DOI: 10.1109/GRSS-CHILE.2017.7996015.

Se presentan las variaciones recientes del área glaciar en el Cerro O'Higgins (1976–2017), Campo de Hielo Patagónico Sur (CHS), las que han sido obtenidas a partir de imágenes de satélites pasivas. Con estas imágenes se calcularon también las velocidades de dichos cuerpos de hielo, alcanzándose...


Bravo, C., Loriaux, T., Rivera, A., and Brock, B. W. (2017) : "Assessing glacier melt contribution to streamflow at Universidad Glacier, central Andes of Chile" Hydrol. Earth Syst. Sci, 21, 3249-3266, https://doi.org/10.5194/hess-21-3249-2017.

Glacier melt is an important source of water for high Andean rivers in central Chile, especially in dry years, when it can be an important contributor to flows during late summer and autumn. However, few studies have quantified glacier melt contribution to streamflow in this region. To address th...

Cooper (2017) : "Antarctic ice sheet discharge driven by atmosphere-ocean feedbacks at the Last Glacial Termination" Scientific Reports 7, Article number: 39979, DOI:10.1038/srep39979.

Reconstructing the dynamic response of the Antarctic ice sheets to warming during the Last Glacial Termination (LGT; 18,000–11,650 yrs ago) allows us to disentangle ice-climate feedbacks that are key to improving future projections. Whilst the sequence of events during this period is reasonably...
