Figure F49. Whole-core gamma ray attenuation (GRA) bulk density, discrete sample bulk density, grain density, and porosity, and split-core P-wave velocity (PWS3; VP) 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; and 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.
