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...
Baroclinic Boundary Currents and Long Edge-Waves in Basins with Sloping Shores
Baroclinic Boundary Currents Sloping Shores Long Edge-Waves
2009/3/9
Earlier work on baroclinic “coastal jets” and Kelvin waves in constant-depth basins is extended to basins with sloping shores. Baroclinic coastal jets are again found to be set up by an inflow or outf...
We examine the generation of trapped edge waves on a continental shelf when a long wave from the deep ocean reaches an irregular coast, and alterations in the propagation characteristics of trapped ed...
A Variable-Depth Green’s Function for Shelf Edge Tides
Shelf Edge Tides Variable-Depth Green’s Function
2009/2/13
The Green's function for a semi-infinite ocean with depth a function of distance from the boundary is developed numerically for the M2 frequency and with Coriolis frequency and depth profile appropria...
Exact solutions are found to the linearized three-dimensional equations for free surface-gravity waves trapped against a straight coastline with a topography varying perpendicular to the coastline. Th...
Low-Frequency Circulation at the Edge of the Scotian Shelf
Low-Frequency Circulation Scotian Shelf Nova Scotia
2009/2/7
Records of current, temperature and salinity from a two-year mooring program at the shelf break off Nova Scotia are examined to determine the low-frequency oceanic responses to the driving surface win...
The Generation of Barotropic Edge Waves by Deep-Sea Internal Waves
Barotropic Edge Waves Deep-Sea Internal Waves
2009/1/20
A simple two-layer, step-shelf model is used to demonstrate that barotropic (surface) edge waves of substantial amplitude can, in principle, be generated by deep-sea internal waves incident upon the c...
A Heat Balance for the Bering Sea Ice Edge
marginal ice zone Marginal Ice Zone Experiment Heat Balance
2009/1/16
Detailed oceanographic, meteorological and sea ice observations were obtained from the Bering Sea marginal ice zone (MIZ) during the February–March 1983 Marginal Ice Zone Experiment (MIZEX West). Thes...
A Statistical Description of the Vertical and Horizontal Structure of Eddy Variability on the Edge of the Gulf Stream Recirculation
Statistical Description Vertical Horizontal Structure Eddy Variability Gulf Stream Recirculation
2009/1/15
The vertical structure of eddy variability on the southern edge of the Gulf Stream recirculation is presented as a number of different forms of empirical orthogonal modes. The velocity dot-product mod...
Observations of the Shelf-Edge Current South of Australia, Winter 1982
Shelf-Edge Current South of Australia
2009/1/12
Results are presented from an oceanographic cruise along Australia's south coast in June–July 1982. A narrow shelf-edge current flowed eastwards along the shelf edge for the entire distance. Features ...
Large-Scale Lateral Entrainment and Detrainment at the Edge of a Geostrophic Shear Layer
edge of a quasi-geostrophic shear layer potential vorticity
2009/1/8
The evolution of large-amplitude disturbances at the outer edge of a quasi-geostrophic shear layer depends on the sign of the outward gradient of potential vorticity. Entrainment of ambient water can ...
Modeling Interpretation of Mesoscale Meanders of the Ice Edge off the Labrador Coast Observed in NOAA Satellite Imagery
Mesoscale Meanders NOAA Satellite Imagery Ice Edge
2009/1/8
NOAA satellite visible images exhibit two alternative ice-edge patterns off Labrador; one is a straight pattern, and the other is a large-meander pattern with alongshore wavelengths of 200–300 km and ...
Infragravity Edge Wave Observations on Two California Beaches
Infragravity Edge Wave California Beaches Wavenumber-frequency spectra
2009/1/7
Wavenumber-frequency spectra of the infragravity (periods 20-200 sec) wave velocity field in the surf zone of two California beaches are estimated. Because the longshore arrays of biaxial electromagne...
Application of Turbulence Energy Models to the Computation of Tidal Currents and Mixing Intensities in Shelf Edge Regions
Tidal Currents Shelf Edge Regions Mixing Intensities
2008/12/9
The major steps in the formulation of a three-dimensional shelf edge model using a sigma coordinate system in the vertical are briefly described. Vertical diffusion of momentum is parameterized using ...
Dynamics of Dense Water Cascades at the Shelf Edge
Dynamics Dense Water Cascades Shelf Edge
2008/12/3
Plumes of dense shelf water cascade down continental slopes in many parts of the world’s oceans and provide a mechanism for shelf–ocean exchange. In this paper a nonlinear process-orientated theory is...
