Figure 55. Hamilton Frame velocity and computed anisotropy for the sedimentary sequence in Holes 899A and 899B. The vertical velocity was measured along the axis of the core. Horizontal velocities were measured perpendicular to the core axis (Hx) and normal to the split face of the core (Hy), The downhole increase in the vertical velocity shows a linear trend (dashed line) with a correlation coefficient (R) of 0.85.
