Figure F27. Whole-core gamma ray attenuation (GRA) bulk density, discrete sample bulk density, and grain density, porosity, and split-core P-wave velocity (PWS3) for the sediments of Site 1256. Open symbols = anomalous values. Also shown is the simplified lithostratigraphy, blue = nannofossil ooze, orange and yellow = clay, silt, or silty clay, shades of purple = diatom-rich intervals. Dashed lines = the boundary between lithologic Units I and II at 40.6 mbsf, the top of the diatom mat at 111 mbsf, and a physical property boundary at ˜205 mbsf. The GRA density data have been smoothed by averaging over a 41-point (102.5 cm long) window.
