TOMODEC. High resolution seismic tomography of Deception Island (Antarctica), and modelling of seismo-volcanic sources. Bathymetryc data and derived products.
Progress Code: completed Statement: Since the experiment was designed to perform two legs of shooting and they were done in an inverse way, we used this advantage to perform a calibration of the multi-beam sounder and observed almost minor corrections such as Roll: 0.04 degrees, Pitch: 0.3 degrees,...

Purpose We present recently collected swath data for the seas within and around Deception Island. We use these data to assess the effects of ongoing volcanic activity in the caldera and to evaluate recent models for the tectonic evolution of the island. In January 2005 a multi-parametric international experiment was conducted that encompassed both Deception Island and its surrounding waters. This experiment used as main platforms the Spanish Oceanographic vessel 'Hesperides', the Spanish Scientific Antarctic base 'Gabriel de Castilla' at Deception Island and four temporary camps deployed on the volcanic island. This experiment allowed us to record active seismic signals on a large network of seismic stations that were deployed both on land and on the seafloor. In addition other geophysical data were acquired, such as: bathymetric high precision multi-beam data, and gravimetric and magnetic profiles. During the whole period of the experiment a multi-beam sounding EM120 was used to perform bathymetric surveys. The characteristic of this sensor permitted to reach up to 11.000 m b.s.l.
