Multi-channel seismic reflection survey shot logs 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 shot logs in ASCII format. These were pulled directly from the ship's Seapath system and are not corrected for layback of the airguns. Assuming perfect towing, the center of source is ~55m back from these coordinates (the ship's (0,0,0) reference origin), and a few m offset laterally. Several different towing configurations were used so shot location varied between lines, but these corrections are small enough compared to the other length scales that they do not much matter for processing. Detailed geometry information about the seismic survey is in the cruise report, allowing shot coordinates to be corrected accordingly, if required. 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.
