Figure F23. Whole-Round Multisensor Logger (WRMSL) gamma ray attenuation (GRA) bulk density compared to WRMSL magnetic susceptibility (MS) data, Site U1421 shown after Gaussian smoothing both data sets with a 10 cm window (±3σ) and interpolation to constant resolution at 2.5 cm. WRMSL MS (κ; black) is also shown corrected for variability in recovered sediment volume by normalizing to WRMSL GRA bulk density, generating mass MS (χ; blue). Data in the shallowest 32 m CCSF-A reflect the stratigraphic composite splice (see “Stratigraphic correlation”); data from the deeper APC-acquired cores and from the extended core barrel portions of Hole U1421A are appended to form a single stratigraphic section.
