The Atlantic Meridional Overturning Circulation (AMOC) is a key regulator of global climate. Recent paleoclimate research has demonstrated that large changes in the AMOC strength played a significant role in the abrupt climate changes that occurred during the last ice age. In particular, Heinrich Stadial 1 (HS1) (~17.8 ka) was characterized by ice rafting, abrupt cooling across the Northern Hemisphere and weakening of the AMOC. It is imperative that we gain a better understanding of past AMOC dynamics in order to anticipate its role in future climate change. Our work seeks to better understand past dynamics of the AMOC by studying deep-sea sediment proxies, such as foraminifera δ13C and δ 14C concentrations, foraminifera species abundances and percent ice rafted debris (IRD) in deep-sea cores from the Greenland and Labrador Seas within the pathway of the present AMOC flow.
