**Figure 7.** Seismic velocity structure from Muller et al. (1997). **A.** *P*-wave
seismic velocity model on the north south seismic Line CAM101 of Muller
et al. (1997). The velocity contour interval is 0.3 km/s. Numbered OBH
positions are shown on the seafloor. The position of ODP Hole 735B has
been projected from 1 km west of the line. The Moho is indicated as a
thicker line where its depth is constrained by wide-angle reflections.** B.**
Resolution contours for the seismic model. The resolution of each velocity
node is given by the diagonal of the inversion resolution matrix a number
between 0.0 and 1.0, affected by the ray coverage sampling each node.
Values of greater than 0.5 are considered well resolved and reliable.
