A: VSP waveforms recorded in Hole U1399C. The direct arrival time picks are marked by green crosses. B: Comparison of travel time data from the VSP and P-wave velocity from the sonic logging tool, with pre-cruise predictions for velocity at this site (1800-2200 m/s). Red stars indicate VSP depth stations.
