Figure F36. Comparison of the abundance of benthic foraminifers (BF), planktonic foraminifers (PF), and benthic ostracodes (ostra) in the upper section of Site 1086 (last 4 m.y.). A. BF/PF vs. BF/g. B. BF/g vs. PF/g. The minima and maxima are similarly positioned in the two indices. C. Abundance pattern of ostracodes compared with BF/g. (All indices are on log scale.) P/P = Pliocene/Pleistocene boundary, G/M = Gauss/Matumaya reversal.
