Figure F15. Summary of logs recorded by the modified Formation MicroScanner (FMS)-sonic tool string, Hole U1399C. Hole size is measured by the two orthogonal calipers of the FMS (C1 and C2). Gamma ray recorded during the FMS-sonic run is compared to gamma ray recorded by the triple combo run (TC). Total gamma ray from the Hostile Environment Natural Gamma Ray Sonde (HNGS) is shown alongside natural gamma radiation (NGR) data from Hole U1399A cores. The high waveform coherence, in red in the velocity tracks, is a measure of the reliability of the slowness/time coherence algorithm used to derive compressional (VP) and shear (VS) wave velocities from the monopole and lower dipole sonic waveforms, respectively.
