Figure F8. Summary of seismic stratigraphy near Hole 1149D showing generalized correlations with lithologic units, ages, and seismic facies. UT = upper transparent, UO = upper opaque, and HB = Horizon B. Hole 1149D imaged with MCS air guns (4 × 466 in³) of C2005 Line 39 collected in 1976. The location was chosen where the sediment section appeared to thin onto a basement high. Track-line orientation and location are shown in Figure F7. Seismic data were reprocessed from CDP gathers and displayed with the following parameters: prestack predictive deconvolution; 24-fold stack; noise filter; band-pass filter 5-40 Hz; spherical divergence gain; and vertical exaggeration of ~8× at the seafloor.
