Figure F9. Portions of the GRA bulk density records from Site 1171. Data from each hole are smoothed (21 cm Guassian) and offset by a constant for clarity. A. Cores from Holes 1171A (solid line), 1171B (dotted dashed line), and 1171C (dashed line) on the mbsf depth scale. B. The same cores on the meters composite depth (mcd) scale. The composite depth section has the advantage that features common to all holes are in relative alignment. C. The spliced GRA bulk density record assembled from the same Site 1171 cores shown in the left and middle panels. In this example, Hole 1171A was used as the backbone. Intervals from Holes 1171B and 1171C were used to cover gaps present in the Hole 1171A record.
