TOMODEC. High resolution seismic tomography of Deception Island (Antarctica), and modelling of seismo-volcanic sources. GRAVIMETRIC DATA

Listed in NASA Earthdata CMR

In January 2005 a multi-parametric international experiment was conducted that encompassed both Deception Island and its surrounding waters.

Description

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.
