a–f, Age model construction for the intermediate-depth site4,17. a, Radiocarbon dates (points) calibrated using the Marine20 curve21 and the modelled depth–age relationship (median line with 1σ range). b, Sedimentation rate (median line with 1σ range). c, The depth conversion used to align 85JC to U1419. d, The normalized and weighted RMSE of GRA and MS misfits as a function of the deviation from the depth conversion in c. e, Aligned magnetic susceptibility records. f, Aligned GRA density records. g–k, Age model construction for the abyssal site20. Only MS was used for alignment in this case. g, Radiocarbon dates (points) calibrated using the Marine20 curve21 and the modelled depth–age relationship (median line with 1σ range). h, Sedimentation rate (median line with 1σ range). i, The depth conversion used to align 87JC to U1418. j, The normalized RMSE of MS misfit as a function of the deviation from the depth conversion in i. k, Aligned magnetic susceptibility records.
