José Uribe, Rodrigo Zamora, and Andrés Rivera (2017) : "High resolution FM-CW radar for internal layers mapping in cold ice" First IEEE International Symposium of 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...


Jonathan Oberreuter, Sebastián Pulgar, and Andrés Rivera (2017) : "An integrated bathymetric and seismic profiling system" First IEEE International Symposium of Geoscience and Remote Sensing (GRSS-CHILE), DOI: 10.1109/GRSS-CHILE.2017.7996020.

We developed a system that integrates bathymetric and seismic measurements. The system consists of an active transducer, hydrophone streamer and an electronic unit. The source waves travel through water, they reach the water/sediment interface, one part is reflected back to the surface and the ot...


Rodrigo Zamora, José Uribe, Jonathan Oberreuter and Andrés Rivera (2017) : "Ice thickness surveys of the Southern Patagonian Ice Field using a low frequency ice penetrating radar system" First IEEE International Symposium of 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 ...


Michal Petlicki (2017) : "Inferring Subglacial Topography of the Emerald Icefalls (King George Island, Antarctica) from Ice Surface Terrestrial Laser Scanning" First IEEE International Symposium of Geoscience and Remote Sensing (GRSS-CHILE), DOI: 10.1109/GRSS-CHILE.2017.7996014.

Information about ice thickness and subglacial 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...


Jorge HERNÁNDEZ, Pablo PAREDES, Daniela CARRION y Andrés RIVERA (2017) : "Ice elevation changes surveyed with Airborne Laser Scanning Data" First IEEE International Symposium of 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 tas...


Sebastián Cisternas, Claudio Bravo, y Andrés Rivera (2017) : "Recent glacier area variations at Cerro O'Higgins (48°30'S, 73°10'W), Southern Patagonian Icefield" First IEEE International Symposium of 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 v...
