(2022; doi:10.1594/PANGAEA.943562), covering the upper 0 - 7.16 m core section down to Heinrich Event layer H2, was revised and extended to the full core length of 10.64 m, including now also Heinrich Event layers H3 to H5a. The age model was first extended back to 34.6 ka using two older 14C AMS dates by Lars Max (doi:10.1594/PANGAEA.943562). This radiocarbon chronology now covers H1 – H3 within inferred age brackets of 15.3 to 17.3 ka (H1), 23.3 to 25.3 ka (H2) and 28.5 to 30.5 ka (H3) respectively. The ages of the older Heinrich Event layers H4 – H5a were obtained by correlating the Ca/Sr and d18O records to the NGRIP chronology, obtaining age brackets of 38.3 to 39.8 ka (H4), 47.2 to 49.0 ka (H5) and 55.9 to 56.2 ka (H5a). Between these age tie points, we linearly interpolated sediment ages in 1 cm depth increments and assigned Heinrich Event numbers (H1 to H5a) and (Heinrich-related) interlayer numbers (I1 to I6) to the respective stratigraphic units.
