Figure 28. PWL acoustic velocity measurements in cores from Hole 898A. PWL data (dots) were sorted to eliminate data that had poor signal strength; only measurements when signal amplitude exceeded 1000 (arbitrary units) are plotted. The clay velocity gradient (dashed line) is the linear velocity gradient that was estimated from the discrete velocity measurements taken with the DSV and Hamilton Frame Velocimeter.
