Abstract : The long range goal of this project was to quantify the dynamical mechanism responsible for the exchange of mass, momentum and energy between the coastal and open oceans. Nonlinear mechanisms operating on sub-grid scales, dynamically consistent and quantitative methods for interpreting quasi-Lagrangian data, and nonlinear/nonquasigeostrophic flows were the main study. The first was to determine the role of secondary circulation on the exchange between the coastal and open oceans. The second was to determine how ocean eddies produce super inertial fluctuations in hydrodynamic fields. As documented in the scientific literature, considerable progress was made on these questions. It is expected that this research contributes to improved parameterizations of sub-grid scale processes and to efficient utilization of quasi-Lagrangian data.
