From: Younger Dryas ice margin retreat triggered by ocean surface warming in central-eastern Baffin Bay
Results from core SL 170 compared with relevant paleoclimate data. a August sea surface temperature (aSST) reconstruction (°C). b Marginal Ice Zone assemblage factor. c Arctic Water assemblage factor. d East−West Greenland Current assemblage factor. Thick lines in a–d indicate smoothed records (five points weighted average). e Fine grain size fraction; <63 µm (%). f Sedimentation rates (cm/ka). g Time-distance diagram of Jakobshavn Isbræ extent modified from Cofaigh et al.18. Distances are calculated from the modern Greenland Ice Sheet margin. Black circles indicate 14C dates, for the dashed line the ice margin position is unknown. h AMOC rate presented as sedimentary 231Pa/230 Th from the subtropical North Atlantic ocean5. i Stable oxygen isotope δ18O record from the NGRIP1. j Mean monthly insolation values for June at 68°N for the last 20 kyr46. Green dashed line indicates average modern summer (July) SST (5 °C)16. Red dashed lines marks the limits of YD (12.9–11.7 kyr BP) based on NGRIP1. When comparing with the previously published data included in the figure, we would like to refer the reader to our Supplementary Note 3, where the effect of different reservoir age corrections on our chronology has been tested
