Figure F12. A, B. Comparison between bulk density measured by gamma ray attenuation (GRA) and 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 3 (PWS3) and BD (MAD method) measurements.
