Abstract:
This 2D multi-channel seismic data set was acquired during SONNE cruise SO241 offshore Mexico in the Guaymas Basin in June 2015. MCS data were collected using a Geometrics GeoEel streamer of variable active lengths, such as 150, 162, 175, and 187 m with 96, 104, 112, and 120 channels, respectively. The hydrophone group spacing was 1.56 m. The seismic source signal was generated by two generator-injector (GI) air guns, each with a volume of 210 cubic inches or 3.44 l (1.72 l generator and 1.72 l injector). The air guns were operated in harmonic mode at a tow depth of 2 m. The shot interval was 7 s, resulting in a mean shot point distance of 12 m. The recording time was 4 s, and the sampling rate was 1 ms. Navigation is based on ship GPS and lay backs. Locations are given in UTM zone 12N. Seismic data processing was funded by VBPR AS and carried out with RadExPro. It included common mid-point (CMP) binning with a CMP bin spacing of 3.125 m; band pass filtering using an Ormsby filter with corner frequencies of 20, 45, 250, and 400 Hz; normal move-out correction (NMO); and true amplitude recovery. The NMO-corrected gathers were stacked, and subsequently, a post-stack Stolt migration with 1500 m/s velocity was carried out. Detailed information on the data acquisition can be found in the SO241 cruise report (https://doi.org/10.3289/CR_S241).
