The original multi-channel seismic (MCS) data were acquired in 2001 onboard the seismic R/V Maurice Ewing (cruise EW0102) using a 6-km-long, 480-channel hydrophone streamer towed at a nominal depth of 10 m. A tuned 10-element air gun array with a total volume of 3,100 cubic inches, deployed at a nominal depth of 8 m, was used as the seismic source. The shot and group spacing was 37.5 m and 12.5 m, respectively, and the data recording length was 10 s with a sampling rate of 4 ms. The distance between the air gun array and the closest channel was ~200 m. The MCS data employed in this study include three dip profiles (K4, K1, K8) and three strike profiles (K5, K6, K7) at the Kane oceanic core complex (OCC). Here we present advanced seismic imaging techniques to map the structural variability within the Kane OCC from full waveform inversion and reverse time migration of long streamer seismic data
