<p><strong>The Atlantic Meridional Overturning Circulation (AMOC) and the production rate of the North Atlantic Deep Water (NADW) are major components of the North Atlantic climate-system, with important hemispheric climatic influences. The post-glacial history of the AMOC, as reconstructed from Nd-isotopes (&#949;</strong><strong>Nd) in biogenic minerals and sediments</strong><strong>, demonstrates its sensitivity to freshwater fluxes, </strong><strong>leading to concerns about its near-future response to the ongoing accelerated Greenland/Arctic ice melting</strong><strong>. Whereas the early Holocene inception of the deep NADW components originating from the Nordic Seas has been well documented from such &#949;</strong><strong>Nd-data, information on the status of its western, shallower and most sensitive component, the Labrador Sea Water (LSW), is still missing. New &#949;</strong><strong>Nd-measurements in corals from the Labrador Slope provide the means to fill this gap. These data demonstrate that convection in the Labrador Sea was fully implemented by ca. 4 ka BP only, i.e., well after the final demise of the Laurentide ice-sheet. The time- and space-transgressive pattern of the full AMOC inception implies more complex driving mechanisms than meltwater fluxes only. </strong><strong>Whereas the late Holocene neo-glacial cooling trend could have played here a minor role, the penetration and strengthening of the Irminger Current into the Labrador Sea has likely been the driving force. </strong></p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
