| contents | Included here are 3D post-stack time migrated data from the Kolumbo Volcano in the Aegean Sea. The data were collected aboard RV Poseidon in 2019 during Research Cruise POS538 using GEOMAR's P-Cable seismic system. Seismic source was a Generator-Injector airgun fired in harmonic mode with generator and injector volumes of 45 cubic inches. The source was towed at a nominal depth of 2 m beneath the sea surface. Shot interval was 4 seconds at a ship speed of ~3.5 knots. Gun pressure was set at 200 bar. The receiver geometry consisted of 16 streamer sections attached to a 199 m long cross cable. Processing included: 3D geometry application, trace editing, static time corrections, anomalous amplitude attenuation, FK filtering, pre-stack trace interpolation, adaptive subtraction multiple suppression using a 1D pattern matching algorithm, sorting to common midpoint gathers, normal moveout correction (1517 m/s constant velocity), stacking, trace interpolation, 3D FK coherency filtering, 3D Stolt migration (1517 m/s constant velocity), residual 2D finite difference migration (first inline, then crossline). The dataset has a horizontal resolution of 3.125 m (bin size) and a dominant frequency of ~100 Hz. Acquisition and processing details are included in the EBCDIC header of the SEG-Y file. |
