Raw multi-channel seismic reflection data (SEG-Y format) from the Jurassic Quiet Zone, western Pacific (SKQ202418S, 2024-2025)

This MCS data set was acquired with the Scripps Institution of Oceanography portable multi-channel seismic system during a survey of the Jurassic Quiet Zone area in the western Pacific Ocean, during Sikuliaq cruise SKQ202418S in late 2024 and early 2025. The data set contains the raw MCS field shot data files, in SEG-Y format. The "source" coordinates in the headers were pulled directly from the ship navigation and so are referenced to the ship coordinate system, not to airgun or streamer location. The airgun array was towed 25 m from the stern of the ship, and the first channel of the streamer was ~185 m offset from the airgun array. More detailed geometry information is in the cruise report. The navigation coordinates in the headers are in UTM-57N, though parts of the survey are outside the nominal limits of that UTM zone. The data set was acquired as part of the project called Resolving the Origin of the Jurassic Quiet Zone. Funding was provided by NSF awards OCE22-21814 and OCE22-21815.
