Lagrangian characteristics of continental shelf flows forced by periodic wind stress
Lagrangian characteristics continental shelf flows periodic wind stress
2009/11/11
The coastal ocean may experience periods of fluctuating along-shelf wind direction, causing shifts between upwelling and downwelling conditions with responses that are not symmetric. We seek to unders...
Relative Diffusion as Related to Quasi-Periodic Current Structures
Quasi-Periodic Current Structures Lake Huron
2009/3/9
Experiments were performed in Lake Huron in which the relative diffusion of a dye plume and the lateral component of turbulent velocity were measured simultaneously. The standard deviation of the plum...
An infinitely deep stratified ocean on a equatorial beta plane is forced with a periodic wind system. The resulting linearized motion is shown to result in a deep cellular flow structure in rough agre...
Mean Flow Generation on a Continental Margin by Periodic Wind Forcing
Mean Flow Generation Continental Margin Periodic Wind Forcing
2009/1/21
The generation of an alongshore mean flow by the nonlinear interaction of forced barotropic shelf waves over a continental margin is studied using a wind-forced, f-plane model with bottom friction in ...
Internal Kelvin Waves Generated by Quasi-Periodic Mesoscale Motion along the Coast
Internal Kelvin Waves Quasi-Periodic Mesoscale Motion Coast
2009/1/16
In a two-layer model with a rigid surface and a flat bottom on an f-plane, an internal Kelvin wave is forced by quasi-geostrophic, mesoscale meanders of a coastal current. These meanders are assumed t...

Intermediate Models Slope Flow Fields Barotropic Continental Shelf Numerical Model Solutions
2008/12/30
The study of intermediate models for barotropic continental shelf and slope flow fields initiated in Parts I and II is continued. The objective is to investigate the possible use of intermediate model...

geostrophic vorticity geostrophic momentum linear balance equations
2008/12/27
As part of a program to improve understanding of the dynamics of the complicated, vigorous eddy and jet flow fields recently observed over the continental shelf and slope, we investigate the potential...
Multiple Equilibria, Periodic, and Aperiodic Solutions in a Wind-Driven, Double-Gyre, Shallow-Water Model
shallow-water western boundary currents quasigeostrophic
2008/12/11
A reduced-gravity shallow-water (SW) model is used to study the nonlinear behavior of western boundary currents (WBCs), with particular emphasis on multiple equilibria and low-frequency variations. Wh...
Biweekly Periodic Deep Flow Variability on the Slope Inshore of the Kuril–Kamchatka Trench
Biweekly Periodic Deep Flow Slope Inshore Kuril–Kamchatka Trench
2008/7/4
Five long-term current records are analyzed to investigate the temporal variability for deep flows, from a single mooring fitted with two current meters on the slope inshore of the southern end of the...
Breathing sediments: The control of diffusive transport across the sediment-water interface by periodic boundary-layer turbulence
Breathing sediments diffusive transport sediment-water interface periodic boundary-layer turbulence
2014/5/22
We performed combined in situ measurements of bottom boundary-layer turbulence and of diffusive oxygen fluxes at the sediment-water interface in a medium-sized mesotrophic lake. The turbulence was dri...
