Figure F12. A, B. Comparison between bulk density measured by gamma ray attenuation (GRA) and the moisture and density (MAD) methods. C. Correlation of grain density (GD) with bulk density (BD; MAD method). D. Correlation of porosity with BD (MAD method). E. Correlation of P-wave velocity sensor (PWS3) measurements and BD (MAD method).
