Fresh water is a scarce yet strategic resource. Its availability and accessibility have a great impact not only on human lives, as it is a source of social and economic development, but also on all living organisms on ...

The Viedma glacier is the largest glacier in Argentina and one of the most dynamic in the Southern Patagonian Icefield. It is a strategic water source. This study analyzes the interactions of glaciological variables that ...

Main aim of this work is to explore the suitability of high resolution SAR images for measuring ice flow velocity within glaciers. Available techniques for this purpose are Differential SAR Interferometry (DInSAR) and ...

Glaciers are sensitive indicators of climate change. Particularly, glacier surface velocity constitutes a key parameter for estimating ice volume variations as response to global warming and its incidence in sea level rise. ...

Un nuevo campo de drumlins, flutes y megaflutes ha sido identificado en el sector oriental del Lago Viedma (49º 48´ S, 77º 55´ O). En este trabajo se describen y reconocen sus elementos integrantes. Este campo de geoformas ...

The valley of Lake Viedma represents one of the main ice flow axes during the Quaternary glaciations of Patagonia. Geomorphological mapping of the eastern sector of the lake, between the shoreline and the end moraine systems ...

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 ...
