2D multichannel seismic reflection processed data (GI Gun working area dataset) of RV SONNE during cruise SO292, Queensland Plateau, Coral Sea

The seismic data were collected on the Queensland Plateau during RV SONNE expedition SO292 in spring 2022 (Betzler et al., 2022). The seismic signals were generated by two simultaneously released GI-Gun (true GI-Modus; primary volume of 45 in3) and a Mini-GI source (true GI-Modus; primary volume of 15 in3), towed 41 m behind the ship's stern and in a water depth of ca. 2.5 m. Sources were released by a GPS-controlled PC every 18.75 m at 160 bar. To synchronize seismic sources and trigger the recording system, a SureShot trigger system was used. This system allowed to display and adjust the source signatures measured by hydrophones attached to the seismic sources for each shot and therefore enabled an online quality control during the watchkeeping. The streamer was a Hydroscience Technologies SeaMUX 144-channel system with an active length of 600 m and symmetric group interval. The recording length was set to 4 s, the sample interval was 1 ms. Raw data were stored in SEG-Y format. […]
