Notes: Depths and ages of green clay layers (GCLs) are interpolated using splices and age models provided in Wang, Prell, Blum, et al. (2000). Gamma ray attenuation (GRA) values of GCLs and background sediments are converted to porosity using the coefficient obtained from least-square regression of GRA (smoothed and sampled at all moisture and density intervals) against porosity (data in Wang, Prell, Blum, et al., 2000). miss = missing data.
