Figure F17. Downhole variations of percent blue reflectance (450-550 nm), volume-specific magnetic susceptibility, bulk density determined by gamma-ray attenuation (GRA; line = smoothed data) and moisture and density (MAD; open circles), and natural gamma radiation (lines = smoothed data from different holes) at Site 1094. Dashed lines indicate marine isotopic stages inferred from peaks in blue reflectance that represent carbonate peaks.
