Surface mixing and biological activity in the four Eastern Boundary Upwelling Systems
Surface mixing biological activity four Eastern Boundary Upwelling Systems
2009/10/30
Eastern Boundary Upwelling Systems (EBUS) are characterized by a high productivity of plankton associated with large commercial fisheries, thus playing key biological and socio-economical roles. Since...
The seasonal variation of large-scale upwelling off northwestern Mexico is investigated by means of the divergence of the Ekman transport, computed for a 1° latitude-longitude grid. It is found, by us...
A wind-driven model of coastal upwelling induced into a stratified, rotating ocean is solved numerically. The circulation is on an f plane and longshore variations are neglected. A multilevel model is...
A Multi-Layer Transient Model of Coastal Upwelling
Multi-Layer Transient Model Coastal Upwelling
2009/4/2
The transient development of wind-driven coastal upwelling in a rotating, stratified ocean is simulated using a four-layer numerical model. All longshore derivatives in the velocity field are neglecte...
Upwelling and Coastal Jets in a Continuously Stratified Ocean
Coastal Jets Continuously Stratified Ocean Upwelling
2009/4/2
A simple, linear, two-dimensional, f-plane model of coastal upwelling in a continuously stratified ocean is investigated. The transient response of the fluid to an impulsively applied alongshore wind ...
Upwelling Layers in a Steady, Wind-Driven Stratified Ocean
Upwelling Layers Wind-Driven Stratified Ocean
2009/4/2
A theoretical study is made of a region of steady upwelling adjacent to the eastern boundary of a stratified ocean. A multi-layered structure is required to satisfy all the boundary conditions. The ve...
The Effect of Bathymetry on the Coastal Upwelling of Homogeneous Water
Bathymetry Homogeneous Water Coastal Upwelling
2009/4/2
The influence of bathymetry upon the wind-driven, steady-state coastal upwelling motion of homogeneous water is investigated. The motion occurs in two principal layers, a divergent surface Ekman layer...
Linear and nonlinear two-layer ocean circulation models of coastal upwelling on an f-plane are driven by time-dependent winds and solved numerically. Longshore variations in the circulation are neglec...
The β effect is found to produce a poleward undercurrent in a wind-driven model of an eastern ocean circulation. The model is on an x, z plane and longshore derivatives of the velocity field are negle...
Lagrangian Measurements in a Coastal Upwelling Zone off Oregon
Coastal Upwelling Experiment Lagrangian Measurements
2009/3/26
During August 1972 drogue and hydrographic measurements were made in the coastal upwelling zone off the Oregon coast. The study was conducted as a component of the Coastal Upwelling Experiment (CUE-1)...
Longshore Currents and the Onset of Upwelling over Bottom Slope
Longshore Currents Onset of Upwelling Bottom Slope
2009/3/26
The evolution of longshore currents produced by upwelling on an f-plane over shelf-like bottom topography for times long compared to a barotropic spin-up time, but short compared to a diffusion time, ...
Longshore Currents, Upwelling and Bottom Topography
Longshore Currents Bottom Topography Upwelling
2009/3/26
The effect of shelf-like bottom topography on a steady, linear, stratified, three-dimensional model of coastal upwelling is examined. It is shown that the presence of the bottom slope 1) reduces the r...
The three-dimensional circulation produced in a homogeneous ocean by a steady wind stress is investigated when the bottom topography contains a discontinuity in gradient, such as occurs at the edge ...
The relationship between coastal upwelling and coastal long-short currents is studied in a simple model of a continuously stratified fluid in a closed basin on the f-plane. It is shown that the coasta...
On the Possibilities of Coastal, Mid-Shelf, and Shelf Break Upwelling
Coastal Mid-Shelf Shelf Break Upwelling
2009/3/24
The steady-state circulation on a continental shelf under the combined influence of a wind stress, a surface density distribution, and a longshore current over the shelf break is investigated in a lin...
