Geophysical data acquisition - OGS

• Offshore gravimetric survey “CERVETERI”. The gravimetric offshore program
in the area covered by the IGM 1:50000 “CERVETERI” sheet was executed for
the “Servizio Geologico Nazionale” with a floor gravimeter Lacoste &
Romberg on the ship N/R VEGA owned by Sopromar. 300 points, with a 1-km
interval between them, have been measured.
• Integrated methodologies at the Doria Cave. This test was carried on to define
the applicability of the ERT, GPR and magnetometry in detecting underground
caves in Karst area.
• High-resolution mono-channel seismic Acque Profonde. The investigated area
comprehended sea/littoral, lagoon and continental/fluvial multiple
environments in the Marano Lagoon. The survey was carried out by the
employment of two high-resolution acquisition systems linked to a satellite
positioning system. The first was composed by a Delph monochannel
acquiring system synchronized with a Uniboom high frequency
electrodynamical impulse source. The second by an integrated acquiringenergizing
Chirp-datasonic system using a non-impulsive high frequency
source, allowing centimetric resolutions.
• High Resolution Survey in the Barcis Lake. Research project for the “Regione
Friuli Venezia Giulia” with monochannel seismic. A Uniboom energizing
source, a Delph acquiring system and a DGPS positioning system were
mounted on a boat provided by the Barcis municipality.
During this year Salvatore Barbagallo and Giorgio Cova have retired: we would
like to thank them for their work.
