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...

Continental Shelf Waves Bottom Topography Alongshore Variations Coastline
2009/3/7
The effects of alongshore variations in bottom topography and coastline on the wind-stress-forced barotropic motion over a continental shelf and slope are studied. Perturbation methods are used to obt...
The Effects of a Variable Coriolis Parameter, Coastline Curvature and Variable Bottom Topography on Continental Shelf Waves
Variable Coriolis Parameter Coastline Curvature Variable Bottom Topography Continental Shelf Waves
2009/3/7
The effects of a variable Coriolis parameter, coastline curvature and variable bottom topography on continental shelf waves are examined for the case when the variations occur on a length scale much g...
The Influence of Bottom Topography on Upwelling off Peru
Bottom Topography Upwelling off Peru
2009/2/18
The x-y-t, two-layer β-plane numerical model developed by Hurlburt (1974) is used to examine the upwelling system off Peru. The region off Peru from 14 to 15°30's is one of strong and persistent upwel...
Propagation of Barotropic Continental Shelf Waves over Irregular Bottom Topography
Barotropic Continental Shelf Waves Irregular Bottom Topography
2009/2/16
Using a geometry which roughly approximates that of a typical continental shelf and slope, the effects of a random bottom topography on free barotropic shelf waves are found. The bathymetric irregular...

2009/2/13
The effects of alongshore variations in bottom topography on wind-stress-forced barotropic motion over a continental shelf and slope are studied. An idealized channel model with a weakly sloping botto...
Satellite Observations of the Influence of Bottom Topography on the Seaward Deflection of the Gulf Stream off Charleston, South Carolina
Bottom Topography Seaward Deflection Gulf Stream
2009/2/13
High-resolution thermal infrared data from the NOAA polar orbiting satellites are studied for the Gulf Stream between Florida and Cape Hatteras from the fall of 1974 to the spring of 1977. The sea sur...
Quasi-Geostrophic Waves in a Stratified Ocean with Bottom Topography
upper layer component lower layer component Quasi-Geostrophic Waves
2009/2/9
Quasi-geostrophic waves in a two-layer ocean with bottom topography on a β-plane are examined in detail. The bottom slopes in an arbitrary direction but gently and uniformly. A clear understanding of ...
The Interaction of a Two-Layer Isolated Mesoscale Eddy With Bottom Topography
Bottom Topography Eddy size mesoscale eddy
2009/2/6
The propagation of an isolated mesoscale eddy onto a western bounding topographic slope is examined through the use of a two-layer, primitive equation, numerical model. Variable parameters in the stud...
The Influence of Bottom Topography on Baroclinic Transports
Bottom Topography Baroclinic Transports
2009/2/6
A new and reduced set of governing equations is proposed for the modeling of baroclinic motions in a two-layer system with variable bottom topography. The reduction of the equations, which eliminates ...

Near-Inertial Wave Bottom Topography Mean Flow Caryn Seamount
2009/1/10
Velocity measurements near Caryn Seamount in the Sargasso Sea reveal intensified mean and near-inertial motions in the upper ocean. Embedded in a regional eastward flow is an anticyclonic eddy that ap...
