This investigation presents data from working with Global Positioning System (GPS) to complement the work of Radio Echo Sounding from January 2009 at the area next to the Chilean Base Station Bernardo O’Higgins and Jakenau Mountain at north of the Antarctic peninsula (63° 19’ S, 57° 51’ W).
The main objective was to georeference the information onto crevasses zones identified by Radio Eco Sounding, using two topographic GPS equipment. The measured points correspond to a grid draw on the area that is normally used for Twin Otter aircraft landing thus, surface and subglacier topography

In January 2009, Radio Echo Sounding (RES) measures were made during the campaign in the northern part of the Antarctic Peninsula, at the surroundings of the Chilean Base Bernardo O’Higgins (63° 19’ S; 57° 53’ W). The system has three main components: Transmitter, Receiver and a Data Acquisition System. The transmitting antenna, penetrating the ice and then returning to the receptor after their reflection in an internal target or bedrock, carries out radio frequency signals generated by the transmitter. The records are stored in a data acquisition system for post processing purposes. All radar data collected was georeferenced with post-processed GPS measurements. With the Radar and GPS data we will obtain the surface and subglacial topography.
