The dataset comprises parts of reflection seismic lines obtained offshore Saudi Arabia in the Red Sea. These were collected from 15 to 24 September 2023 as part of the RV Meteor M193 cruise, using a 144-channel digital streamer and an array of two GI guns with a total volume of 150 in³. The guns were fired in GI mode at 160 bar every 25 m. The streamer had an active length of 600 m and hydrophone group intervals of 4.167 m. The data were digitised at a sampling interval of 1 ms with a record length of 4 seconds. The streamer was kept 3–5 m below the sea surface using four navigational control units ('birds'). Navigation was provided by the shipboard Seapath GPS system. The seismic lines were processed using Halliburton-Landmark SeisSpace software, which included band-pass filtering (20–200 Hz), spherical spreading correction and 2D surface-related multiple estimation and subtraction to suppress multiples. To correct for reflection-point smearing caused by dipping reflectors in stacked data, pre-stack ensemble dip moveout correction in T-X domain was applied. The data were then stacked with a bin size of 12.5 m. Post-stack time migration was conducted to accurately position dipping reflections and collapse diffraction events. To improve the imaging of seismic reflections beneath the salt layer, a final bandpass filter (20–60 Hz) was applied. This study was funded by grant GPF 21-1/026 – REPLENISH from the Deutsche Forschungsgemeinschaft, and aimed to reveal the tectonic regime in the northern Red Sea, off the Al Wajh carbonate platform and adjacent to the Mabahiss Deep.
