Subpolar North Atlantic western boundary density anomalies and the Meridional Overturning Circulation
Changes in the Atlantic Meridional Overturning Circulation have potential to drive societally-important climate impacts, which have been traditionally linked to the strength of deep water formation in the subpolar North Atlantic. Yet there is neither clear observational evidence nor agreement among...

Changes in the Atlantic Meridional Overturning Circulation have potential to drive societally-important climate impacts, which have been traditionally linked to the strength of deep water formation in the subpolar North Atlantic. Yet there is neither clear observational evidence nor agreement among models about how changes in deep water formation influence overturning. Here we use data from a trans-basin mooring array (OSNAP—Overturning in the Subpolar North Atlantic Program) to show that winter convection during 2014-2018 in the interior basin had minimal impact on density changes in the deep western boundary currents in the subpolar basins. Contrary to previous modeling studies, we find no discernable relationship between western boundary changes and subpolar overturning variability over the observational time scales.
