Figure 6. Paleoenvironmental data, Antarctic Neogene, replotted from data given in Mackensen et al. (1992) (green and blue) and Wright and Miller (1992) (red). Top - planktonic and benthic foraminiferal 18O values. Note that for clarity, planktonic values are plotted with a 2 offset to the benthic data. Middle - 13C values for planktonic and benthic foraminifera. Bottom - percent CaCO3 in Site 751 sediments. Gaps in data in all three plots reflect either hiatuses or unmeasured intervals.
