Abstract:
Summary statistics of posterior marginal distribution of the onset of abrupt warming transitions located in the last glacial age of the NGRIP record, based on both the d18O and Ca2+ proxy. Includes both statistics for the onset depth as well as age transition. Onset depth is found by applying a linear ramp function (Erhardt et al. 2019) which is combined with a probabilistic age-depth model to infer the onset age of the transition.
