Session Description:
It is now beyond dispute that the Arctic is experiencing rapid climate change. There remain many open questions about the future of the Arctic and how changes occurring here will impact the lower latitudes. In the Arctic and subpolar Arctic, freshwater inputs from rivers and glaciers are dispersed across the shelves where vigorous mixing from winter convection, winds and tidal dissipation transform water masses. The mechanisms controlling export from the shelves and other cross-slope exchange processes including eddy fluxes and Arctic Ocean lateral intrusions carrying Atlantic heat, salt and biogeochemical tracers into the central Arctic basins are likely to be sensitive to changing ice and freshwater conditions but remain unresolved. Boundary current dynamics interacting with separate first-order shelf-slope exchange processes set the stratification in the Arctic and the sub-polar Arctic seas i.e. Greenland, Irminger, Norwegian, Labrador and Bering, and are likely to ultimately impact deep convection and meridional overturning. We invite physical and biogeochemial contributions from colleagues focusing on shelf and slope processes, especially shelf-slope exchange, boundary current dynamics, freshwater dispersion and communication between the high Arctic and subpolar Arctic seas.
