Testing Turbulence Closure Models against Oceanic Turbulence Measurements
2001Abstract : The long-term goals of this project are to quantify turbulence and to understand the dynamics and implications of turbulent mixing in the coastal ocean.

Expressing oceanic turbulence parameters by atmospheric turbulence structure constant
Applied Optics, 2016The parameters composing oceanic turbulence are the wavelength, link length, rate of dissipation of kinetic energy per unit mass of fluid, rate of dissipation of mean-squared temperature, Kolmogorov microscale, and the ratio of temperature to salinity contributions to the refractive index spectrum.

Small-Scale Oceanic Turbulence
1980Publisher Summary The analysis of small-scale turbulence spectral characteristics has led to the revision of earlier existing notions of oceanic turbulence as a well developed flow at very high Reynolds number. In most cases, the turbulence in the ocean has no clear-cut ranges of universal similarity, a consequence of the small values of the Reynolds

Ocean Acoustics Turbulence Study
2000Abstract : The long-term goals are to: 1. Measure the three-dimensional wave number spectrum of ocean turbulence using high frequency broadband acoustic scatter. 2. Quantify the acoustic scatter that results from medium variability while other sources of scattering commonly found in the ocean are present.

Turbulent dispersion in the ocean
Progress in Oceanography, 2006Abstract The mathematical framework for turbulent transport in the ocean is reasonably well established. It may be applied to large-scale fields of scalars in the ocean and to the instantaneous or continuous discharge from a point. The theory and its physical basis can also provide an interpretation of passive scalar spectra.

1998
The distributions of flows and water properties in the world’s oceans exhibit structure on a vast range of space and time scales. The largest scales (of order 107m) are limited chiefly by the size of ocean basins and ultimately of the earth. On the other end of the spectrum, gradients in velocity and water properties exist to sub-meter scales (see ...

Oceanic and interstellar fossil turbulence
AIP Conference Proceedings, 1988Turbulence in the stratified ocean is inhibited at large scales by gravity, leaving internal waves and partially mixed fluctuations in the density field called fossil turbulence. Information about previous turbulence activity is preserved by the fossil remnants of 3‐D and possibly 2‐D turbulence.

Scale-Dependent Ocean Wave Turbulence
1997Wave turbulence is a common feature of nonlinear wave motions observed when external forcing acts during a long period of time, resulting in developed spectral cascades of energy, momentum and, possibly, other conserved integrals. In the ocean, wave turbulence occurs on scales from capillary ripples and to those of baroclinic inertia-gravity and Rossby

Weak Turbulence in Ocean Waves
2002Abstract : The long-term goal is to further develop weak turbulence theory, which is used to predict the evolution of spectral energy density in ocean surface waves and internal waves. Isolate, identify and quantify sources of possible discrepancies between numerical solutions of weak turbulence modeling and observations of ocean waves.
