Panel (a) shows the difference in sea surface temperature cooling (ΔSST) between the Holocene and the Last Glacial Maximum calculated using the isotope-enabled Community Earth System Model (iCESM) as shown in Tierney et al. 28. In the background together with ΔSST calculated using corrected Mg/Ca values measured on N. pachyderma (symbols). For a list of all datasets used, please see Supplementary Table 7. Panels (b) and (c) show Holocene and LGM SSTs, respectively, with the modelled (iCESM) SSTs in the background and corrected Mg/Ca-based SSTs shown as symbols. Maps were produced with Ocean Data View93. Please note that modelled annual SSTs are likely too cold for a direct comparison with N. pachyderma-based SSTs, given their seasonal reproductive cycle. Maps displaying uncorrected Mg/Ca values against modelled paleo data are shown in Supplementary Fig. S5. Source data for all panels are provided as a Source Data file.
