Arctic Freshwater Cycle: Land/Upper-Ocean Linkages

The hydrologic cycle and heat balance of the Arctic/SubArctic atmosphere, landmass, and ocean are important components of the Earth system. They couple with the global meridional overturning circulation of the ocean and hence become a key element of the larger climate system. In the Arctic, the fluxes and transformation of freshwater, heat and tracers are rapid, changeable and incompletely observed or understood. An understanding of the freshwater system is a key to understanding the environmental impacts from changing global or regional climate. This Solicitation seeks proposals that address the physical, chemical, and/or biogeochemical processes of the Arctic freshwater system and its connections with the subpolar oceans and Arctic environmental change.
