Our long-term goal is to understand how energy is supplied to the ocean, and how it subsequently cascades to the turbulence and mixing important to the circulation, and the transport and distribution of tracers. This problem involves scales spanning sub-inertial motions to turbulence, and therefore requires integrative efforts with other sea-going investigators and numerical modelers. The South China Sea project was an ideal opportunity to investigate the cascade from internal tides to higher frequency waves though the processes of internal wave scattering and non-linear steepening. Objectives To determine sites of high turbulence dissipation at the generation site. To parameterize the turbulence at topography using easy-to-measure parameters such as the surface tidal forcing and the background ocean stratification. To determine the nature of the internal wavefield radiating from the generation sites. To predict the advent of internal solitary waves in various environments based on external forcing.
