Figure F16. Composite and spliced gamma ray attenuation (GRA) bulk density data for the black shale sequence from Holes 1259A (black), 1259B (blue), and 1259C (green). The composite data from Holes 1259B and 1259C are offset by a constant (0.5 and 1.0 units, respectively) for illustration purposes. All data sets are smoothed with a 9-point Gaussian filter.
