Figure F17. Gamma ray attenuation (GRA) bulk density data for Holes 1219A (leftmost curve in each panel) and 1219B plotted vs. composite depth. The data from Hole 1219B are offset by a constant for illustration purposes. All data sets are smoothed with a nine-point Gaussian filter. Intervals with obvious flow-in or drilling disturbance are removed from the data sets (see Table T8).
