Description 
Summary

During the month of July 1989, the Osservatorio Geofisico Sperimentale conducted a geophysical survey of the Sardinia Channel, collecting magnetic and seismic data. The research has been carried out in cooperation with Istituto di Geologia (Universi degli Studi, Parma), Istituto di Geologia Marina (CNR, Bologna) and the Geologic Departments of ENIS-SFAX (Tunisia). A total amount of 1,002 km of multi-channel seismic lines has been collected in the period from 10th to 27th July, 1989. Along the first line (502 km) marine magnetic data have also been collected. The data have been obtained with the following sampling parameters: Coverage = 3000 % Sample Rate = 4 ms Shot Interval = 50 m Streamer Length = 3000 m Streamer Depth = 12 m Group Interval = 25 m Number of Groups = 120 Record Length = 14 sec Air-Guns: - Total Volume = 80.4 l - Pressure = 140 bar - Depth = 6 m
