Site location. a Location of core MD99-2284 (star), NGRIP ice cores (black circle)101, and other sediment cores (yellow circles) and deep-sea corals (yellow triangles) discussed in this study. The white areas indicate the extent of Northern Hemisphere ice sheets at 12500 years BP102. Red and white arrows show warm Atlantic inflow to the Nordic Seas and main bottom current pathways in the northern North Atlantic. Simulated winter (March, purple) and summer (September, orange) 50% sea-ice cover fraction during GS-1 (12,500 years BP)103 is also shown. b Meridional section of radiocarbon concentration within the Atlantic Ocean (averaged over 0–40°W) from a pre-industrial control simulation using a coupled climate-biogeochemical model104
