Abstract:
The data comprise high-resolution multi-channel reflection seismic profiles from the Ewing Terrace on the Argentine Continental Margin that were acquired during RV SONNE cruise SO260/1 in 2018. Multichannel seismic data were acquired with a SERCEL Mini GI-Gun and GI-GUN with 0.2 l and 0.4 l volumes for generator and injector, respectively. For receiving the signal, a 96-channel analogue TELEDYNE streamer was deployed featuring varying channel spacing of 1 m to 4 m distance. Shot intervals varied between 4 to 6 seconds depending on the water depth, yielding shot spacing of ~10-15 m at a ship's speed of 5 to 5.5 kn. The sampling rate was set to 0.25 ms and the recording length varied between 3 and 4 seconds. The data were band-pass filtered, stacked and migrated with an emphasis on high resolution imaging and noise reduction. Velocity fields were picked interactively for NMO-correction and post-stack time migration. CMP bin distance was set to 2 m. Processing was conducted using the VISTA 2014 seismic data processing software.
