Figure F30. A. Synthetic seismogram plotted on line MAR20. B. Seismic megasequence definition. C.P-wave velocity data. D. Two-way traveltime-to-depth conversion. E. Bulk density. F. Lithologic units and ages. The traveltime-vs.-depth plot links seismic reflection events to depth in the cores, as shown for positions of Megasequence C/D and B/C boundaries. Dashed lines indicate high-amplitude reflections on line MAR20 (see Fig. F29, ), which coincide with prominent shifts in downcore density and velocity measurements.
