Circulation and partitioning of dense water through the submarine Greenland-Scotland Ridge
The densest water supplying the Atlantic Meridional Overturning Circulation (AMOC), which helps maintain the temperate climate of northwest Europe, stems from the Greenland Sea and crosses the submarine Greenland-Scotland Ridge through deep passages east and west of Iceland. While the exchange flows across the ridge have been monitored for decades, the circulation and partitioning of the upstream flows that are co-located northeast of Iceland are not yet quantified and understood. The EU-funded SUPERFLOW project will identify the sources and quantify the transports of these dense-water pathways using unpublished 2-year long observational time series from northeast of Iceland with a high-resolution, realistic simulation from an ocean model. Results will contribute to accurate predictions of how the AMOC will respond to climate change.
