"Chapter 25. Biogenic carbonate production and preservation change between 5 and 10 Ma from the Ceara Rise, Western Equatorial Atlantic." D.L. Murray and L.C. Peterson Table 3. Data for Site 928 samples. Notes "^a Estimated from GRAPE measurements for the composite. Before calculating densities for the composite of GRAPE, we adjusted Holes 928B" " and -928C GRAPE values to be consistent with Hole 928A data. From 150 to 170 mbsf, 0.1 was added, and from 170 to 190 mbsf, 0.2 was added." "^b Anomalously low measurements of GRAPE for this interval in the composite, so we assumed either constant values or a linear change in" density between reliable GRAPE data adjacent to the interval. ^c No magnetic susceptibility data were available for this interval so we assumed linear change across this depth interval.

composite. Before calculating densities for the composite of GRAPE, we adjusted Holes 928B" " and -928C GRAPE values to be consistent with Hole 928A data. From 150 to 170 mbsf, 0.1 was added, and from 170 to 190 mbsf, 0.2 was added." "^b Anomalously low measurements of GRAPE for this interval in the composite, so we assumed either constant values or a linear change in" density between reliable GRAPE data adjacent to the interval. ^c No magnetic susceptibility data were available for this interval so we assumed linear change across this depth interval.
