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...

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...

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...

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...
