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 āDā numbers (see
Fleitmann et al. 2011 and Nicholson et al. 2020 for further details on
Y99).
