Figure F14. Composite digital image, magnetic susceptibility, natural gamma radiation, sediment lightness (L*), and gamma ray attenuation (GRA) bulk density across the E/O boundary interval (153.1–133.2 mcd). The boundary is present in an upward lithologic transition from brown clay to light brown nannofossil ooze and is reflected in an increase in sediment L* and a decrease in magnetic susceptibility, natural gamma radiation, and GRA bulk density.
