Session Description:
Currents at the very surface of the ocean transport buoyant biological material including eggs and Sargassum, debris and contaminants such as oil, and fundamentally impact fluxes of momentum, heat and moisture across the air-sea interface. Though few observations have been made of currents at the very surface (within the upper few centimeters) of the ocean, it is understood that substantial shear can exist between the surface and depths of one to several meters deep, where most of the observations approximating the surface current are taken (e.g., from drifters with drogues, upward-looking ADCPs, or coastal radar). Not only is the velocity structure of the upper few meters poorly observed and its dynamics not fully described, but it is also unresolved in ocean models. As a consequence, for many applications involving numerical calculations of surface transport of biological materials and oil, crude parameterizations are often used to adjust ocean model currents to account for the unresolved vertical shear due to wind and waves. This multidisciplinary session invites contributions on the measurement and physics of surface currents and applications to biological and contaminant transport and air-sea fluxes modified by currents.
