Figure 3

Dark grey column denotes significant slowdown/shutdown of AMOC within GS-1 (divergence between atmospheric and Atlantic marine 14C ages >2 sigma). The onset of the YD is as defined in Meerfelder Maar8. Latitudinal migration of the Intertropical Convergence Zone (ITCZ) over the tropical Atlantic as inferred by the Cariaco Basin greyscale is also shown.
