Figure 9: Interval velocities from one-way traveltimes to VSP receiver depths [Leg 118 Shipboard Scientific Party, 1989]. The dashed line connecting the squares represents raw velocities, which are sensitive to small subjective errors in the selection of seismic arrivals. The solid line connecting the circles indicates velocities after smoothing by a five-point moving average and is a more reliable indication of seismic velocity. The numbered annotations are the lithologic units drilled. [Swift et al., 1991]
