PL52A:
Turbulent Pathways and Deep-Ocean Ventilation I

Session ID#: 92697

Session Description:
There has been rapid progress in our understanding of how the deep and abyssal ocean communicates with mid-depth waters and the thermocline through turbulent processes and through southern polar dynamics. This session aims at bringing together studies that focus on the central role of turbulent processes in maintaining the ocean circulation and global tracer budgets, and thereby in the climate system. The key aim  is to demonstrate the controlling connections of processes to the "big picture" circulation and tracer budgets, and not to focus exclusively on process studies or model-data analysis. Southern Ocean or Arctic dynamics, deep ocean diapycnal mixing, and boundary turbulence are just some of the processes of relevance which should be considered. Theoretical, observational and computational approaches are welcome and hybrid studies combining these approaches are particularly encouraged.
