Seismic reflection data of profile across the Central Basin Fault and the Kyushu-Palau Ridge

Seismic reflection profiles were acquired in 2020 by the R/V "Dayanghao" (Second Institute of Oceanology, Ministry of Natural Resources, China) using a 6040 cubic inch air gun array, discharged at 37.5 m intervals, and a 6-km-long, 480-channel streamer. Data were recorded for 14 s at 2 ms sampling intervals. Seismic data processing involved noise reduction, signal enhancement via filtering and deconvolution, velocity analysis, time migration, and depth migration.
