Figure F29. Preliminary IDEAL sonic-while-drilling P-wave velocity picks compared with core velocity data (solid circles), Leg 131 Hole 808B (blue curve) and Hole 808E (black curve) wireline logs, and Hole 808E vertical seismic profile values (black bars; rectangles = formal error of line fit [Moore, 1993]). Heavy line near depth axis shows extent of casing.
