TOMODEC. High resolution seismic tomography of Deception Island (Antarctica), and modelling of seismo-volcanic sources. GRAVIMETRIC DATAEntry ID: TOMODEC_2005_GRAVIMETRY-SPAIN
Abstract: 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.
The gravimeter BELL AEROSPACE-TEXTRON BGM-3 (at the present Lockheed Martin Federal Systems) is an acquisition system that can be used both in aerial and marine vehicles. The system has a sensor mounted in a gyro-stabilized platform. This system is composed of a gravimeter sensor, the stabilized platform and an acquisition system. Raw data are recorded and processed in a computer HP-486/50 using the own BGM software providing two types of data, raw and previously analyzed data. Acquired raw data are presented in the following format: $PRAWGRV, Day, Hour, Flag, Mean Value,. However, the analyzed data are transformed into: $PHESGRV, Day, Hour, Flag, Mean Value, Value GRS67, Eotvos Correction, sinv, sinv. Potential 'flag' values associated to the sensor status are: 0: normal, 2: error, 5: starting.
Purpose: To obtain marine gravimetric profiles.

Quality 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.
