Figure F37. Integration of core, downhole logging, and seismic data, Site U1421. Two-way traveltime calculated from core P-wave logger (PWL) and P-wave caliper (PWC; solid symbols = automatic velocity picks, open symbols = manual velocity picks) measurements and from sonic log velocities (see text for details). Velocity extrapolated using downhole sonic log values from the deepest sonic log data (~675 m WMSF) to the bottom of the hole.
