Figure 7From: Wide-angle refraction experiments in the Daito Ridges region at the northwestern end of the Philippine Sea plateExamples of forward modeling using observed later phases to constrain the velocity distribution of the entire crust. (a) Observed record section (top) and ray diagram (bottom) for OBS58 of line ODr9. The position of the OBS is shown in Figure 6a, b. (b) Observed record section (top) and ray diagram (bottom) for OBS 124 of line ODr9. The position of the OBS is shown in Figure 9a, b. The reduction velocity is 8 km/s and calculated travel times are shown on the record section.Back to article page
