A Framework for a Marine Biodiversity Observing Network Within Changing Continental Shelf Seascapes
Changing Continental Shelf Seascapes Biodiversity Observing
2015/7/17
Continental shelves and the waters overlying them support numerous industries as diverse as tourism and recreation, energy extraction, fisheries, transportation, and applications of marine bio-molecul...
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...
Wind–Induced Baroclinic Motions at the Edge of the Continental Shelf
Wind–Induced Baroclinic Motions Continental Shelf
2009/4/2
In a two-layer model of stratified fluid flow, motions in the internal mode are governed by the distribution of an equivalent depth he. For a typical continental shelf, the distribution of he with dis...
Continental Shelf Waves：Low-Frequency Variations in Sea Level and Currents Over the Oregon Continental Shelf
Continental Shelf Waves Sea Level Low-Frequency Variations Oregon Continental Shelf
2009/4/2
Sea level variations and currents on the Oregon continental shelf exhibit wavelike characteristics in a frequency band from approximately 0.15 to 0.45 cycle per day (cpd). Shelf wave dispersion curves...
A Subsurface Ribbon of Cool Water over the Continental Shelf off Oregon
Subsurface Ribbon Cool Water Continental Shelf off Oregon
2009/3/26
Observations of the hydrographic regime over the continental shelf off Oregon from the R/V Yaquina during the summer of 1972 showed the presence of an alongshore, subsurface ribbon of relatively cool ...
We study below with the aid of linearized equations, but using a quadratic bottom friction law, the barotropic forced (aperiodic) response to wind stress or external pressure gradient of various simpl...
A Numerical Investigation of Pressure-Induced Storm Surges Over the Continental Shelf
A Numerical Investigation Continental Shelf Pressure-Induced Storm
2009/3/9
A nonlinear, two-layer model of pressure-induced surges at the ocean edge is developed. The bottom topography is taken to approximate the continental shelf and continental slope region. The Coriolis p...
Circulation and c over the Ghana Continental Shelf during the 1974 Upwelling
Ghana Continental Shelf 1974 Upwelling 1974 Upwelling
2009/3/7
The changes in the circulation and hydrographic structure over the continental shelf south of Tema, Ghana, during the 1974 upwelling are described. For the first time in this region an Aanderaa curren...
Continental Shelf Waves and Alongshore Variations in Bottom Topography and Coastline
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...
Current measurements from three stations along the east coast of Florida at about 300 m water depth with a maximum longshore separation of 180 km were used to analyze for the presence of propagating w...
The Transmission and Decay of Barotropic Topographic Rossby Waves Incident on a Continental Shelf
Barotropic Topographic Rossby Waves Continental Shelf
2009/3/7
We know that long-period (>1 day) and long-wavelength (>100 km) topographical Rossby waves can be generated by a wind acting directly on a continental shelf (Adams and Buchwald, 1969). Here we examine...
Previous studies of forced, long continental shelf waves on an f-plane have considered motion on the shelf and slope which is driven by an alongshore component of the wind stress, essentially through ...
Wind Stress on the Ocean over the Eastern Continental Shelf of North America
Wind Stress North America Eastern Continental Shelf
2009/3/7
In the summer season the 32-year climatological wind stress is toward the northeast, having a magnitude close to 0.25 dyn cm−2 throughout the entire shelf region. In the three other seasons the ...
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...
Continental Shelf Currents in Tropical Storm Delia：Observations and Theory
Continental Shelf Currents Tropical Storm Delia
2009/3/7
Storm currents are a significant part of the design hydrodynamic flow field in areas subject to tropical storms. In September 1973, Tropical Storm Delia passed over the instrumented Buccaneer platform...
