The data set constitutes a total of 84 2D multichannel seismic lines acquired in parallel 2D mode across Venere mud volcano. An additional 7 lines were acquired across a grid of 12 OBS deployed in the region. Data are fully processed and migrated (in time). Main processing steps include: Geometry definition, Common-Mid-(CMP) Point sorting, Normal-Moveout-Corrention (NMO) using an average velocity function (extracted from ocean-bottom-seismometer data), Stacking and FK-Migration (in time). Data processing was completed using the VISTA processing package, provided by Schlumberger to GEOMAR. Data acquisition for this survey started with profile P1001 on June 21, 2017 (at 17:30, CET) at a position of 38°34.42'N, 17°08.66'E. Data acquisition for this survey ended with profile P1102 on July 2, 2017 (at 04:00, CET) at a position of 38°40.39'N, 17°07.97'E.

The data are provided in SEG-Y format.
