Description:
The data are a processed and interpolated P-Cable 3D seismic data cube. The data were collected during expedition POS515 with the research vessel POSEIDON (Riedel et al., 2017) in the Mediterranean Sea, Calabrian Arc offshore southern Italy (map under further details). Seismic source was a Generator-Injector airgun fired in harmonic GI mode with generator and injector volume of 105 cubic inches. The source was towed at a nominal depth of 2 m beneath the sea surface. We deployed a P-Cable system made from 12 parallel streamers (each 12. 5 m in length). Details on the towed geometry are given in Figure 30 of the cruise report (Riedel et al., 2017). The P-Cable data were acquired over the course of 6 days during POS515 starting from 13:45 on July 5, 2017 until 12:06 on July11, 2017 (all CET). Processing included: 3D geometry application, trace editing, static time corrections, band-pass filtering, sorting to common midpoint gathers, normal moveout correction (1520 m/s velocity ), and stacking. The stacked 3D cube was then interpolated to fill any empty bins. Afterwards, Stolt time migration (1550 m/s) was performed, first inline, then crossline direction. The dataset has a horizontal resolution of 3.125 m (bin size) and a dominant frequency of ~100 Hz.
