Abstract:
During RV Maria S. Merian cruise MSM71 refraction and wide-angle reflection seismic data were acquired. We present profile P02 consisting of 15 seismic record sections (seg-y format) of the hydrophone components from three ocean bottom hydrophones (OBH204, OBH208, OBH212) and twelf ocean bottom seismometers (OBS201 - OBS203, OBS205-OBS207, OBS209-OBS211, OBS213-OBS215) along the SW-NE oriented seismic profile MSM71-P02, which is situated in the centre of the Ligurian Basin. The profile stretches over a distance of 127 km and was shot using an airgun array of six G-gun clusters with a total volume of 84 l (5440 cu in) at 190 bar. A total of 1079 shots were fired every 60 s (~123 m) with an airgun towed behind the vessel in a depth of 8 m. Data are unprocessed, however, they are corrected for instrument drift along the profile using the symmetry of the direct arrival and the data are time corrected.
