Estimating Internal Wave Energy Fluxes in the Ocean

Creator:

Nash, Jonathan D., Alford, Matthew H., and Kunze, Eric

Abstract:

Energy flux is a fundamental quantity for understanding internal wave generation, propagation, and dissipation. In this paper, the estimation of internal wave energy fluxes <u′p′> from ocean observations that may be sparse in either time or depth are considered. Sampling must be sufficient in depth to allow for the estimation...

Internal Tide Reflection and Turbulent Mixing on the Continental Slope

Creator:

Nash, Jonathan D., Kunze, Eric, Toole, John M., and Schmitt, Ray W.

Abstract:

Observations of turbulence, internal waves, and subinertial flow were made over a steep, corrugated continental slope off Virginia during May–June 1998. At semidiurnal frequencies, a convergence of low-mode, onshore energy flux is approximately balanced by a divergence of high-wavenumber offshore energy flux. This conversion occurs in a region where the...

Microstructure estimates of turbulent salinity flux and the dissipation spectrum of salinity

Creator:

Nash, Jonathan D. and Moum, James N.

Abstract:

Direct determination of the irreversible turbulent flux of salinity in the ocean has not been possible because of the complexity of measuring salinity on the smallest scales over which it mixes. Presented is an analysis of turbulent salinity microstructure from measurements using a combined fast-conductivity/temperature probe on a slowly falling...
