TOMODEC. High resolution seismic tomography of Deception Island (Antarctica), and modelling of seismo-volcanic sources. GRAVIMETRIC DATA
Progress Code: completed Statement: 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 e...
