Cd seawater estimates (CdW) indicate that intermediate‐depth southern source waters crossed the equator and contributed to the Florida Current during the Bølling-Allerød warm period of the last deglaciation, consistent with evidence of only a modest AMOC reduction compared to today. The CdW estimates also provide the first paleoceanographic evidence of a reduction in the influence of intermediate-depth southern source waters within the Florida Current during the Younger Dryas, a deglacial cold event characterized by a weak North Atlantic AMOC. Our results reveal a close correspondence between the northward penetration of intermediate-depth southern source waters and the influence of North Atlantic Deep Water, suggesting a possible link between intermediate-depth southern source waters and the strength of the Atlantic AMOC. STUDY NOTES: Cd/Ca ratios were measured in the tests of the benthic foraminifer Hoeglundina elegans, which records bottom water Cd concentrations with a partition coefficient DP = [(Cd/Ca)foram/(Cd/Ca)water] ≈ 1.0 [Boyle et al., 1995]. The partition coefficient for the aragonitic species H. elegans is constant with depth, unlike the partition coefficients of calcitic foraminifera, which are depth dependent [Boyle, 1992]. A constant seawater Ca concentration of 0.01 mol kg−1 was assumed to estimate Cd water concentrations.
