Near-Inertial Wave Interactions with Mean Flow and Bottom Topography near Caryn Seamount
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...
To demonstrate some effects of a seamount an oceanic flows, we have considered a uniform, two-layer flow passing a right circular cylinder of arbitrary height in a rotating fluid. In the case of vanis...

2008/12/18
Pure oscillatory flow of a rotating, linearly stratified fluid in the vicinity of an isolated topography of revolution is considered in the laboratory. The pertinent dimensionless parameters governing...
Tidally Driven Vorticity, Diurnal Shear, and Turbulence atop Fieberling Seamount
High-Resolution Profiler expendable current profilers
2008/12/3
Fine- and microstructure profiles collected over Fieberling Seamount at 32°26′N in the eastern North Pacific reveal a variety of intensified baroclinic motions driven by astronomical diurnal tides.
A Nonlinear Model of the Shoaling and Refraction of Interfacial Solitary Waves in the Ocean. Part II: Oblique Refraction across a Continental Slope and Propagation over a Seamount
Nonlinear Model Interfacial Solitary Waves Oblique Refraction Continental Slope Seamount
2008/7/25
The refraction of internal solitary waves can be due to variations in water depth, nonlinearity, stratification, or shear. This paper addresses the effects of the first two of these effects. Part I of...
