Figure F13. A, B. Comparison between bulk density measured by gamma ray attenuation (GRA, small dots) and the moisture and density (MAD [large dots]) methods. C. Correlation of grain density (GD) vs. bulk density (BD; MAD method). D. Correlation of porosity vs. BD (MAD method). E. Correlation of P-wave velocity sensor (PWS3) and BD (MAD method) measurements.
