Uribe, J.; Zamora, R.; Gacitúa, G.; Rivera, A. & Ulloa, D. (2014) : "A low power consumption radar system for measuring ice thickness and snow/firn accumulation in Antarctica" Annals of Glaciology, 55(67), 39-48.

In order to measure total ice thickness and surface snow accumulation in Antarctica, we have designed and built a surveying system comprising two types of radar. This system is aimed at having low power consumption, low weight/volume and low construction cost. The system has a pulse-compression ...

Before the satellite era, relatively little was known about the interior of the West Antarctic Ice Sheet (WAIS). Of special interest are the rock outcrops associated with blue-ice areas (BIAs), which have been exploited for logistical purposes as well as being the subject of scientific research....

The first glacier inventory of the islands south of the Estrecho de Magallanes including Isla Grande de Tierra del Fuego, Isla Santa Inés, and Isla Hoste, has been compiled using several ASTER and Landsat ETM+ satellite images acquired between 2001 and 2011, yielding a total glacier cover of 3,28...

Here we present the results of a comprehensive glaciological investigation of Union Glacier (79º46'S/83º24'W) in theWest Antarctic Ice Sheet (WAIS), a major outlet glacier within the Ellsworth Mountains. Union Glacier flows into the Ronne Ice Shelf, where recent models have indicated the potent...

Radio echo sounding has been one of the most utilized techniques in Chile in recent years for measuring ice thickness, particularly for glaciers in the central Chilean Andes and in the Patagonian Ice Fields. In this article, the main surveying systems and the most representative ...

Results obtained by the first intensive airborne surveys carried out at Volcán Villarrica (39ºS) in Southern Chile, are presented. These campaigns included the use of a scanner laser system, for detecting the glacier surface topography, and a helicopter-borne ice penetrating radar, for measuring...
