Leeuwin Current mesoscale eddies chlorophyll cross-shelf exchange geostrophic current finite-size Lyapunov exponent
2009/11/17
Along the downwelling coast off Western Australia, late-autumn/early-winter chlorophyll a blooms are observed on the continental shelf south of Shark Bay (26°S), in contrast with summer blooms in the ...
Eddy growth and mixing in mesoscale oceanographic flows
Eddy growth and mixing mesoscale oceanographic flows
2009/11/13
We study the relation between changes in the Eulerian topology of a two dimensional flow and the mixing of fluid particles between qualitatively different regions of the flow. In general time dependen...
Wavelet ridge diagnosis of time-varying elliptical signals with application to an oceanic eddy
Wavelet ridge diagnosis time-varying elliptical signals oceanic eddy
2009/11/9
A method for diagnosing the physical properties of a time-varying ellipse is presented. This essentially involves extending the notion of instantaneous frequency to the bivariate case. New complicatio...

The method of determining the eddy diffusivity over the open ocean either from profiles of the average electric filed or from average values of space charge and electric field measured near the sea su...
Theory of Steady Wind-Driven Currents in Shallow Water with Variable Eddy Viscosity
Steady Wind-Driven Currents Shallow Water Variable Eddy Viscosity
2009/3/24
A theory is given for steady wind-driven currents in shallow water (friction depth comparable to total depth) in which the vertical eddy viscosity varies linearly with depth, from zero at the bottom t...

Wind-Driven Currents Large Lake Depth-Dependent Eddy Viscosity
2009/3/7
The theory of steady wind-driven currents in shallow water is extended to the case of a spatially variable eddy viscosity of the form ν=ν0eaz, where ν0 and a are constants and z is the vertical coordi...
An experimental method for producing an isolated eddy in a laboratory tank is described, along with the simple viscous theory of the behavior of the eddy in an ordinary cylindrical tank without the β-...
Warm core closed mesoscale eddies have been repeatedly observed off the southeastern coast of Australia. One eddy was observed to close off around latitude 35°S during the period February–March 1975. ...
