Figure F6. Synthetic seismogram computed from the LWD density log and velocity values hand-picked from ISONIC dispersion plots with field seismic data near the reference site (ODP Site 1173). The LWD data were recorded from seafloor to the total drilled depth of the hole. Integrated transit time and LWD logging curves, the primary reflectors and seismic source, and computed synthetic traces are presented in addition to the synthetic–seismic overlay. The synthetic and seismic reflections at the seafloor and at the top of basement correlate well. RHOB = LWD density (g/cm3), DT = LWD compressional slowness (ms/ft).
