<!--!introduction!--> Increasing freshwater fluxes from the Greenland ice sheet and the Arctic have the potential to lead to a dampening of deep convection in the subpolar north Atlantic by increasing stratification in deep convection regions. In turn, this could affect deep water formation and the Atlantic Meridional Overturning Circulation (AMOC). However, it is unclear where and how much freshwater is exported from the Greenland shelf where it first enters the subpolar north Atlantic, to the interior seas where deep convection occurs. In particular, there is still little understanding of exchange processes east of Greenland, while overturning east of Greenland has been shown to be particularly important for the total subpolar AMOC. Using drifter data, satellite altimetry data and winds from an atmospheric reanalysis, we identify areas favourable to cross-shelf exchanges and investigate the respective role of winds, eddies and the mean circulation in these exchanges.
