a, Depth models of cores HM79-4, GIK23074-1 and MD95-2010 constructed using the P_Sequence option in OxCal70. Light-coloured uncertainty envelopes represent the 95.4% quantiles, while darker coloured represent the 68.2% quantiles of the depth model PDF. The models are made by defining tie-point between the cores and core GS07-148-17GC using the records of (b) δ18O44,59,61, (c) δ13C44,59,61, (d) IRD59,61, and (e) magnetic susceptibility59. f, Compiled AMS 14C44,59,61,62. Circles mark the dates that are excluded from further analysis due to distortion of the core stratigraphy from deep burrows (Extended Data Fig. 6). Horizontal error bars in b-f represent the 1σ uncertainty of the depth model for the respective cores.
