Fig. S1. 230Th ages and growth axes for stable isotope sampling of Y99 GI-I.230Th ages marked in blue were not incorporated into (or were removed as outliers) from the StalAge age-depth model. Stalagmite growth discontinuities are marked by ā€œDā€ numbers (see Fleitmann et al. 2011 and Nicholson et al. 2020 for further details on Y99).
