The coldest and densest overflow branch into the North Atlantic is stable in transport, but warming - poster

Poster presented by Karin. M. H. Larsen at the 23rd Arctic-Subarctic Ocean Fluxes Workshop, Barcelona, Spain. Title: The coldest and densest overflow branch into the North Atlantic is stable in transport, but warming Abstract As part of the Atlantic Meridional Overturning Circulation (AMOC), dense water is formed north of the Greenland-Scotland Ridge. On its route southward at depth, the dense water has to cross this ridge. The densest water flows through the deepest passage across the ridge, which is the Faroe Bank Channel (FBC, sill depth of 840 m). As the densest source for the deep limb of the AMOC, the FBC overflow is an important part of its thermohaline forcing. Any changes in the strength or density of the FBC overflow may therefore affect the AMOC. The strength of the flow has been monitored since 1995 together with its temperature and salinity characteristics, which determine its density.
