Figure F11. Comparison of the SCS data after high-resolution enhancement with the synthetic seismogram obtained by directly applying bandpass (BP) filter BP(10, 50, 250, 300) to the reflection coefficient series at shotpoint (SP) 16002. SP 16002 is the closest point of approach to Site 1224. The hydrothermal vein is identified with a reflection of reversed polarity relative to the seafloor reflection.
