Expanded view of interval 7.4–6.9 Ma at ODP Site 1146. a Mg/Ca-derived mixed layer temperatures with (red scale) and without (black scale) correction for secular changes in Mg/Ca of seawater. b ∆δ13C; c Planktic δ13C. d Benthic δ13C. e Planktic δ18O. f Benthic δ18O. Dashed horizontal lines indicate long-term mean of planktic and benthic foraminiferal δ18O for intervals 5.07–7.03 Ma (n = 1114 and 1015) and 7.23–8.00 Ma (n = 454 and 446). Lilac shading marks global δ13C decline coincident with planktic δ18O increase and high-amplitude obliquity modulation of benthic δ18O. Blue shading marks final stage of global δ13C decline. Age correlation points are indicated by crosses; 3 pt smooth: 3 pt moving mean
