Figure F2. Age scale and productivity estimates for Site 1079. A. 18O values of Globobulimina spp. in Hole 1079A and sedimentation rates (SR) linearly interpolated between age control points. Head bar indicates SPECMAP oxygen isotope stages (Imbrie et al., 1984). B, C. Changes in the log-transformed concentration and accumulation rate of benthic (B) and planktonic (C) foraminifers. Shaded intervals = glacial stages. Note the similarity of the foraminiferal concentration and flux records and the fact that glacial periods show higher values than interglacials.
