Figure F4. Results of the VSP at Site 1244. A. and A´. East-west slice from the 3-D seismic reflection data split at the location of the drill hole. B. Traveltime vs. depth data. Manual picks were used. Similar results are obtained using the automatic picks. Gray lines trace primary reflections from time to depth. BSR = bottom-simulating reflector. C. Velocity function derived from the data in B (blue line) is compared to velocities measured with wireline sonic logs. Gray dots = VP, red dots =VS. This plot is included here to illustrate the relationship between time and depth. It is repeated in Figure F5 at larger scale.
