a, comparison of the preferred deposition model (magenta; Extended Data Fig. 1) and our alternative deposition model (cyan). Darker and lighter colour represents the 68.2% and 95.4% credible intervals, respectively. The positions of the Vedde Ash, and the constrained and unconstrained segments of the models are indicated. b, The δ18O record from Hulu cave as in Extended Data Fig. 124. c-d, the MS record of core GS07-148-17GC on the preferred (c, magenta) and alternative (d, blue) deposition model. The horizontal error bars in b,c and d represent the 1σ uncertainty of the OxCal-generated deposition models for the respective records. e, the average of the δ18O records from the Greenland summit ice cores (GISP2 and GRIP aligned on the GICC05 chronology60) plotted for reference. f, the 14C ages of the Norwegian Sea compilation plotted both on our preferred chronology (magenta) and the alternative chronology (blue), the light pink field is the Norwegian Sea 14C reconstruction.
