Abstract: Over the last several decades, there has been growing recognition from both the oceanographic and atmospheric science communities that processes taking place in the vicinity of the ocean surface play a crucial role in the interaction between the atmosphere and the ocean. To better understand the coupling between the atmosphere and the ocean, and in turn to improve our understanding of air-sea fluxes of mass (e.g. gases, aerosols), momentum (e.g. generation of waves and currents) and energy (e.g. heat and kinetic energy for currents and mixing) in coupled ocean-atmosphere models, surface-wave processes must be taken into account. 

In this talk, I will discuss recent progress made in our understanding of the role of surface gravity waves in air-sea interaction and submesoscale dynamics using novel laboratory, in-situ and remote sensing observational approaches. This includes the properties of the directional distributions of wind-generated surface waves across the equilibrium and saturation ranges using airborne topographic lidar data, and the role of wave breaking, both through its contribution to the Lagrangian drift at the ocean surface, and as a source of sea spray-aerosols, using data collected during a series of field experiments off the coast of California. Novel observational techniques that have revolutionized our ability to characterize air-sea interaction processes, such as instrumented unmanned surface or aerial vehicles, will also be discussed.
