Figure F3. Comparison of preservation-related indices at ODP Hole 1079A. Fields from the bottom up are sand fraction (>63 µm), CaCO₃ content, fragmentation (ratio of fragments to whole tests of planktonic foraminifers), and B/P (ratio of benthic to planktonic foraminifers). All values are standardized according to ([x-mean]/standard deviation) and vertically offset (+1) for clarity. Gaps in the fragmentation record are shown where planktonic foraminifers are rare.
