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 ...
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...
Low-Frequency Variations in Currents near the Shelf Break：Northeast Gulf of Alaska
Very low-frequency Low-Frequency Variations Shelf Break
2009/2/9
We present current observations from depths of 20, 50, 100 and 175 m obtained over a 3-year period near the northeast Gulf of Alaska shelf break, and emphasize a 2-year continuous segment from 50 m de...
Tidal and Low-Frequency Currents Near the Shelf-Break：Northeastern Coast of Brazil
Low-Frequency Currents Shelf-Break Brazil
2009/2/6
Time series of a 40-day (13 March-23 April 1979) wind and current observational experiment are analyzed. The wind data originated from the Fortaleza Airport Weather Station (Ceará, Brazil), and the cu...
On the Semidiurnal Internal Tide at a Shelf-Break Region on the Australian North West Shelf
Semidiurnal Internal Tide Shelf-Break Region Australian North West Shelf
2009/1/21
The properties of the semidiurnal internal tide, in the region of the shelf-break, at a location on the Australian North West Shelf are discussed. Information is derived from an analysis of thermistor...
Observation of an Anticyclonic Eddy near the Continental Shelf Break South of New England
Anticyclonic Eddy Continental Shelf New England
2009/1/10
A small scale but energetic and highly nonlinear anticyclonic eddy was observed near the New England Shelf Break in July 1983. Satellite images show a tongue of shelf water 15 km wide flowing offshore...
Hydraulic Jump and Undular Bore Formation on a Shelf Break
Hydraulic Jump Undular Bore Formation Shelf Break
2009/1/6
The evolution of the semidiurnal internal tide as it propagates across the Australian North West Shelf is discussed analytically. As the tide is of long wavelength and small amplitude, this evolution ...
Internal Tides over a Shelf Break：Analytical Model and Observations
Internal Tides Shelf Break
2008/12/27
Data collected on Cruise ONDINE 85 organized by the Service Hydrophique et Ocèanographique de la Marine, at two points (P1 and P6) near the continental shelf break of the Bay of Biscay, show very larg...
The Role of Stratification in the Formation and Maintenance of Shelf-Break Fronts
Shelf-Break Fronts continental shelf stratified fluid
2008/12/22
A mechanism is described for the formation or a front at the edge of a continental shelf in an initially linearly stratified fluid lacking horizontal density gradients. A primitive equation numerical ...
Tidal Rectification and Mass Transport over a Shelf Break：A Barotropic Frictionless Model
Tidal Rectification Shelf Break Mass Transport Barotropic Frictionless Model
2008/12/22
A depth-independent model for the tidal rectification process is developed in order to explain the residual Eulerian velocity observed at the top of a shelf edge. An approximation of the nonlinear equ...
Synoptic Flow and Density Observations near an Arctic Shelf Break
Synoptic Flow Density Observations Arctic Shelf Break
2008/11/24
Analyses of data from three shipborne surveys describe the quasi-synoptic density and velocity fields near Barrow Canyon, Alaska. The canyon parallels the northwestern coast of Alaska and contains thr...

2010/1/7
A 6-compartment biogeochemical model of nitrogen cycling and plankton productivity has been coupled with a 3D general circulation model in an enclosed environment (the Black Sea) so as to quantify and...
