Datasets originate from Eirik Drift, Southeast of Greenland, from IODP site U1305, and sister site MD99-2227. Purple lines show three-point running averages of corrected Mg/Ca-based sea surface temperatures (SSTs), while grey lines show three-point running averages of uncorrected Mg/Ca-based SSTs reconstructions. The blue shading shows the 95% confidence interval associated with Mg/Ca[Corr] SST reconstructions. In orange are Modern Analogue Technique (MAT)-based SSTs reconstructions as shown in Irvali et al.30. for MIS 5 (panel b.), 9 (panel c.), and 11(panel d.). Note that MAT-based SSTs are not available for the last glacial-interglacial transition (panel a.). Source data for all panels are provided as a Source Data file.
