The Iceland-Faroe Slope Jet: a conduit for dense water toward the Faroe Bank Channel overflow
Abstract Dense water from the Nordic Seas passes through the Faroe Bank Channel and supplies the lower limb of the Atlantic Meridional Overturning Circulation, a critical component of the climate system. Yet, the upstream pathways of this water are not fully known. Here we present evidence of a prev...
