The gravimeter is regularly calibrated by the manufacturer, but periodically before every field survey is calibrated in the starting harbor to avoid potential shifts. All these calibration controls are done using a portable gravimeter WORDEN mod. MASTER. In this experiment this control was performed at the Argentinean AeroNaval (Navy and Air) base of Ushuaia on December 29th, 2004, three days before the start of the field experiment. In figure 12 we show the reported calibration folder, written in Spanish, and reported by the operators onboard. 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.
