Extended Data Fig. 4: Age models for cores KNR197-3-25GGC (#3), 46CDH (#4) and 9GGC (#5).
From: Warmer shallow Atlantic during deglaciation and early Holocene due to weaker overturning circulation
Thick colored lines correspond to the median proxy ensemble member, and ribbons denote 95% highest-density probability ranges. Solid symbols denote raw proxy data on their median age. The age model of 46CDH (#4) was constrained by 14C dates and one δ18O tie-point16. If 25GGC and 9GGC age models are only constrained by 14C dates, there is an offset of δ18O maxima between 9GGC and 46CDH at ~14.5 ka, and an offset of δ13C minima between 25GGC and 46CDH at ~9.8 ka (a). We used these isotope peaks as additional age tie-points for the final age models (b). Solid diamonds in the bottom panels indicate radiocarbon-based age control on the median age, and open diamonds indicate isotope tie-points.
