This project in collaboration with Eric Kunze at the University of Victoria aims to increase our understanding of primarily tidal internal wave processes and how they affect diapycnal mixing in the coastal ocean. An eventual goal is the improved representation of baroclinic tides and mixing parameterizations in numerical models. OBJECTIVES To characterize and understand the horizontal and vertical structure of the internal wave field in a region of coherent but weak internal tides, rough topography, and elevated internal wave continuum. To test numerical predictions of internal tide generation and propagation. To estimate rates of internal wave spectral energy transfer through critical reflection, topographic generation, and boundary and internal dissipation. To estimate bottom boundary layer mixing and its effect on internal wave energy budgets and interior stratification. To compare mixing estimates with diffusivities and turbulent fluxes from regional numerical models with a view toward determining the impact of internal waves on simulated distributions of temperature and salinity. To use this information to guide improvements in mixing parameterizations, leading to improved predictions of oceanic properties and air-sea fluxes.
