Description 
Summary

During autumn 1975, a geophysical survey has been conducted of the Black Sea. Seismic reflection and marine magnetic data have been collected along with about 3,500 km of seismic profiles. The survey was performed with the R/V L.F. Marsili, fitted by OGS with dedicated seismic instruments. The research was funded by the Italian National Research Council (CNR). The seismic data have been collected with the following sampling parameters: Coverage = 1200 % (Line BS-1: 600 %) Sample Rate = 4 ms Shot Interval = 100 m (Line BS-1: 200 m) Streamer Length = 2400 m Streamer Depth = 12 m Group Interval = 50 m Number of Groups = 48 Record Length = sec Flexotir: - Total Charge = 100 gr - Depth = 14 m
