 | This project, in collaboration with Eric Kunze at the University of Victoria, aimed to increase our understanding of (primarily tidal) internal wave processes and how they affect diapycnal mixing in the coastal ocean, with an eventual goal of improved representation of baroclinic tides and mixing parameterizations in numerical models. Our work is expected to add significantly to the knowledge of the internal wave field, its interactions with topography, and implications ... |

| The Role of Biologically-Generated Turbulence in the Upper Ocean |

|
| Our interests are in oceanic processes that contribute to stirring and mixing to understand their impact on larger scales so that better sub-grid scale parameterizations may be implemented. This includes phenomena ranging from the microscale (1 cm) up to the mesoscale (10-100 km). Work on ocean biosphere energetics suggests that schooling marine organisms might generate turbulent dissipation rates with as much as 1 TW available globally to generate ocean turbulence. ... |

| Our interests are in oceanic processes that contribute to stirring and mixing in order to understand their impact on larger scales. This includes phenomena ranging from the mesoscale (10-100 km) to the microscale (1 cm). Of particular interest is how different processes interact to produce turbulence and mixing. |

|
| The purpose of this proposal was to support Dr. Eric Kunze, Applied Physics Laboratory, University of Washington (now at University of Victoria) and Dr. Pascale Lelong (via a subcontract to Northwest Research Associates, Seattle, Washington) to numerically explore an alternative solution method to Baines' (1982) internal tide generation theory for arbitrary 1-D topography h(x). The solution method uses characteristic coordinates along which signals of frequency omega propagate. |

| Submesoscale Dynamics near a Seamount. Part 1. Measurements of Ertel Vorticity |

|
| The prevailing view that submesoscale fluctuations (horizontal wavelengths less than a few kilometers and vertical wavelengths less than a few hundred meters) are dominated by internal gravity waves is tested by measuring Ertel's potential vorticity. Unlike geostrophic or nonlinear Ertel vorticity- carrying motions, internal waves have no Ertel vorticity fluctuations. Velocity and temperature profile surveys beside Ampere Seamount reveal appreciable Ertel enstrophy, and thus a significant non-internal-wave component, on horizontal ... |
