a the δ18O (‰) values of deep-dwelling planktic foraminifera (G. miotumida between 11.7 and 5.6 in brown, G. crassaformis between 5.6 and 3.9 Ma in purple and G. inflata between 3.9 and Holocene in red), (b) the δ18O (‰) values of shallow-dwelling planktic foraminifera (G. bulloides in black), (c) the δ13C (‰) values of deep-dwelling planktic foraminifera (G. miotumida between 11.7 and 5.6 in brown, G. crassaformis between 5.6 and 3.9 Ma in purple and G. inflata between 3.9 and the Holocene in red), (d) the δ13C (‰) values of shallow-dwelling planktic foraminifera (G. bulloides in black), (e) Stacked Sea Surface Temperature (SST) anomalies2 for southern hemisphere mid-latitudes (green), northern hemisphere high latitudes (light blue), northern hemisphere mid latitudes (navy blue), and tropics (red). Isotope (δ18O and δ13C) records between 6.1 Ma and the Holocene are obtained from Mohanty et al.11. Five-point running average plots are superimposed on a–d. Dotted bar indicates the timing of initiation of the BUS, Blue bars indicate intervals of cooling and yellow bar represents warm interval.
