Figure F5. Velocity functions at Sites 1244, 1247, and 1250. The velocity function derived from the near-offset vertical seismic profiles (VSP) using a moving window of 20 m in depth is shown as a bold blue line. The velocity function derived from line segments of data delimited by strong reflections is shown in green. The yellow line shows the results obtained when data are separated into segments based on a lithologic change at 160 mbsf. Sonic logging data are shown as gray and red dots for VP and VS, respectively. BSR = bottom-simulating reflector.
