Abstract:
The data set contains 13 2D multichannel seismic lines acquired across Poseidon mud volcano chain, Caalbrian Arc, offshore southern Italy. Data were processed onboard during expedition POS515 with R/V POSEIDON. These lines were also recorded on 12 OBS. Details see cruise report (Riedel et al., 2017). Main processing steps include: Geometry definition, Common-Mid-(CMP) Point sorting (1.5625 m bin-space), Normal-Moveout-Corrention (NMO) using a constant velocity of 1500 m/s and Stacking Stolt-Migration (in time) with constant velocity of 1500 m/s. Data processing was completed onboard using the SU processing package. Seismic Surveying at Poseidon mudvlcano started with line P4001 on July 3, 2017 (08:22 am, CET) at 17°40.12'E, 38°21.58N. The last line acquired in this sequence is line P6010. Surveying ended on July 5, 2017 at 04:00 am (CET) at 17°43.12'E, 38°18.96'N.
