Notes: Smoothed values were used in the generation of synthetic seismograms and time-depth conversion of seismic reflection profiles near the site. * = first arrival time picks associated with depths of observations, † = interval velocities associated with midpoints between depths of observations. LSF = LWD depth below seafloor. — = no data.
