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...


Gomez R.; Arigony-Neto J.; De Santis A.; Vijay S.; Jaña R. and Rivera A. (2019) : "Ice dynamics of union glacier from SAR offset tracking" Global and Planetary Change, v.174, pages 1-15.

The Antarctic ice sheet is predicted to be the major contributor to sea-level rise during the XXI century. Therefore, monitoring ice dynamics of outlet glaciers in Antarctica is of great importance to assess future sea-level rise predictions. Union Glacier is one of the major outlet glaciers of t...


Rivera A. (2018) : "Glaciar Pío XI: La excepción a la tendencia de desglaciación en Patagonia" Revista Geográfica de Chile Terra Australis Vol.54, ISSN 0719-9562 pp. 1-12.

El glaciar Pío XI también llamado Brüggen (49°13'S 74°O), es el más grande del Campo de Hielo Sur (CHS), ha experimentado desde 1945 un aumento neto de área de 126 km² debido a un casi permanente estado de avance con tasas de 150 m/a y un engrosamiento de 2 m/a entre 1975 y 2013. Este comportamie...


Podgórski J.; Pętlicki M. and Kinnard C. (2018) : "Revealing recent calving activity of a tidewater glacier with terrestrial LiDAR reflection intensity" Cold Regions Science and Technology 151: 288–301, DOI:10.1016/j.coldregions.2018.03.003.

In this work we propose a method of estimating the age of calving events of a tidewater glacier based on 3D point clouds. Terrestrial LiDAR scans of the calving front of Fuerza Aerea Glacier (Greenwich Island, South Shetland Islands, Antarctica) were analyzed to determine the timing of the ice fa...


Lenzano M.G.; Lannutti E.; Toth C.; Rivera A. and Lenzano L. (2018) : "Detecting Glacier Surface Motion by Optical Flow" Photogrammetric Engineering & Remote Sensing, 84: 33-42, DOI: 10.14358/PERS.84.1.33.

In this study, we assessed the feasibility of using optical flow, in particular, large displacement optical flow (LDOF) method as a possible solution to obtain surface movement data to derive ice flow velocities in a glacier. Tests were carried out at the Viedma Glacier, located at the South Pata...


Uribe J.; Zamora R. and Rivera A. (2017) : "High resolution FM-CW radar for internal layers mapping in cold ice" First international symposium on geoscience and remote sensing (GRSS-CHILE), DOI: 10.1109/GRSS-CHILE.2017.7996001.

A wideband ground penetrating radar was developed in order to detect internal layers in firn and shallow ice, with high resolution. Mapping of near-surface layers improves traditional snow accumulation measurements, extending the spatial and temporal coverage. This system is a frequency-modulated...
