Figure F6. Comparison of shipboard and reprocessed S-wave slowness logs as function of depth from pass 1 and pass 2 in Hole 1173A. Pass 2 data has higher signal-to-noise ratio due to the use of the low-frequency DSI source, allowing reliable S-wave slowness to be extracted over the entire logged interval. Pass 1 data are used to extract reliable results from 226 to 350 mbsf. The velocity inversion below 350 mbsf is confirmed in the reprocessed pass 2 log.
