Abstract:
The dataset contains ocean bottom hydrophone (OBH) data acquired along profile P05 during RV Sonne Expedition SO267 (project ARCHIMEDES) to the Lau Basin, Southwestern Pacific in December 2018. This seismic refraction data set contains 34 OBS that all recorded the shots along the ~220 km long seismic transect successfully. Data for two different shot intervals (50m and 150m) were acquired shooting from east to west and from west to east respectively. An 84 l airgun array served as seismic source that was towed behind the vessel 8 m below sea surface. The data were processed using standard methods for relocation of the instrument at the seafloor, clock drift correction, deconvolution and filtering.
