Fig. 3: Box plots of deep-sea coral δ234Ui records.
From: Enhanced subglacial discharge from Antarctica during meltwater pulse 1A
a Box plots of deep-sea coral δ234Ui records for each 2-kyr interval over the last 18,000 years and for 30–18 ka (excluding samples from Group I). b Box plots of δ234U results for three groups of deep-sea corals between 16 and 14 ka when high δ234U values are observed. The p-values of a two-sided Wilcoxon rank sum test that assesses the hypothesis of equal δ234U medians are also shown. Source data are provided as a Source Data file.
