Abstract: 

Ocean-atmosphere exchange is one of the most dominant factors affecting our climate. It's therefore critical to understand the processes which influence air-sea exchange.
This presentation will focus on how turbulent processes can be incorporated into parameterisation schemes describing the air-sea fluxes of mass and energy. Specifically field observations are presented which suggests a direct relation between the transfer velocity (k) and the dissipation rate of turbulent kinetic energy (ε). The observations are based on direct measurements of ε conducted by the Air-Sea Interaction Profiler (ASIP) and simultaneous eddy covariance measurements of DMS and CO2 air-sea gas fluxes during the North Atlantic Knorr11 field experiment.
