Figure F10. Correlation between seismic two-way traveltime (ms) and depth for all Leg 194 sites. These data were obtained by check-shot surveys (solid circles), virtual check shots (open circles), and integration of sonic log and shipboard velocity data in between. Virtual check shots are obvious links between high-amplitude reflection on the seismic data and unique petrophysical horizons in the cores (e.g., basement and hardgrounds).
