Figure 41. Acoustic velocity and anisotropy measurements made on cores from the sedimentary sequence in Hole 900A. The vertical velocity (V) was measured along the axis of the core. Horizontal velocities were measured perpendicular to the core axis, parallel to the split face of the core (H_x) and normal to the split face of the core (H_y). The downhole increase in the vertical velocity shows a linear trend (dashed line) with a correlation coefficient (R) of 0.92.
