Summary of synthetic seismogram analyses, Site 1173. (A.) Two-way traveltime (TWT) vs. depth relationship. (B.) Density and velocity curves where velocity is shown as slowness (inverse of velocity). (C). Modeled source wavelet. (D.) Reflection coefficient. (E.) Common depth midpoints (CMPs) 237-256 from Inline 215 with the synthetic seismogram displayed in the center as three identical traces. CMP spacing = 25m.
