Bottom Currents in Wilmington Submarine Canyon

Nature Physical Science, 1971
INTEREST has been increasing recently in submarine canyons because of the question of their origin and the part which they are thought to play in funnelling sediment from the continental shelf to the deep ocean1. Shepard and Dill2 have summarized the evidence concerning bottom currents observed in submarine canyons. Following the pioneer use of current

On Wind‐Driven Currents in an Ocean with Bottom Friction

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1976
AbstractThis paper presents an investigation of the long period response of an unbounded ß‐plane ocean with bottom friction to initial disturbances of wind stress applied at the surface. An analysis is carried out for determining the free and forced barotropic motions generated by stationary or traveling atmospheric winds.

Downward Migration of Dense Bottom Currents

Environmental Fluid Mechanics, 2001
The focus of this paper is on the dynamics of a dense current flowing along the continental slope, and the frictionally induced downward motion it experiences. In particular, the movement of the lateral boundaries where the isopycnals meet the bottom are considered.

A Bottom Current Along the Shelf Break

Journal of Physical Oceanography, 1975
Abstract The theory of Hill and Johnson for upwelling over the shelf break is modified to give agreement with the work of Killworth. It is shown that when upwelling occurs over a discontinuity in bottom slope, this upwelling does not penetrate into the surface Ekman layer.

Dense Bottom Currents

1986
A dense bottom current or a light roof current is the flow created by a source of mass, momentum, and buoyancy flowing into an ambient fluid in such a way that the flow is bounded by the fixed wall and the interface. The dense bottom currents and light roof currents are primarily driven by buoyancy forces.

Longshore Currents, Upwelling and Bottom Topography

Journal of Physical Oceanography, 1974
Abstract 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 role of the lower Ekman layer in the upwelling mass balance, and 2) introduces a barotropic boundary layer which can, depending on a balance of ...

Surface and Bottom Currents in the Strait of Georgia

Journal of the Fisheries Research Board of Canada, 1956
Measurements of the currents close to the bottom and at the surface have been made at six stations along a section across the Strait of Georgia from Point Roberts to Galiano Island, and at two stations in Trincomali Channel. After adjusting to the maximum tidal range the mean bottom currents were about 0.3 knot with a maximum of 1 knot. At the surface

The effect of bottom topography on the Agulhas Current

pure and applied geophysics, 1972
Methods used by Warren and later modified by Niiller and Robinson have been used to investigate the Agulhas Current and other currents associated with it. The results show that with the assistance of a small bottom current of 4 cm/s in the same direction as the main current, the Agulhas Current can proceed round the Cape of Good Hope during three out ...

Baroclinic Instability of Bottom-Dwelling Currents

2001
Density-driven benthic flows are important in the dynamics of marginal seas, river estuaries and other coastal regions (LeBlond et al., 1991; Price & O’Neil Baringer, 1994). They often occur along sloping continental shelves, flowing with shallower water on their right (in the northern hemisphere).

Dense Bottom Currents in Rotating Ocean

Journal of the Hydraulics Division, 1980
A dense bottom current is the flow created by a source of mass, momentum, and buoyancy flowing into an ambient fluid in such a way that the flow is bounded by the fixed wall and the interface. The dense bottom currents are primarily driven by buoyancy forces (reduced gravity).
