In this section, I describe the velocity analysis performed on the data
and discuss the resulting 2-D velocity fields. Furthermore,
I evaluate the possible errors in both RMS and interval velocities and
quantify the interval velocity uncertainty by comparing it with two
vertical-seismic-profile (VSP) velocity profiles from wells 995 and 997
(see Figure ![[*]](http://sepwww.stanford.edu/latex2html/cross_ref_motif.gif)
), both of which penetrate a sharp BSR in the region
of the Blake Outer Ridge.
