Figure F22. Whole-Round Multisensor Logger (WRMSL) gamma ray attenuation (GRA) bulk density from Site U1420, shown after Gaussian smoothing with a 50 cm window (±3σ) and interpolation to constant resolution of 10 cm, compared to equivalently treated natural gamma radiation (NGR) data. NGR is also shown corrected for variability in recovered sediment volume by normalizing to WRMSL GRA bulk density.
