Bottom Currents in the Hudson Canyon

Science, 1973
In-place measurements of the bottom currents in the Hudson Canyon reveal that the current regime is characterized by a pronounced reversal of flow up and down the canyon. Velocities are commonly of the order of 8 to 15 centimeters per second, reaching 27 centimeters per second on occasion in the upper and central portion of the canyon ...

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

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.

BOTTOM SEDIMENTS AND NEAR-BOTTOM CURRENTS IN THE SOUTHWESTERN ATLANTIC

Геология и геофизика, 2015
Abstract On the basis of the author’s data on the composition of sediments and seismic cross sections, together with literature data, the bottom topography was described and the main structural features of the top 10–100 m thick sedimentary sequence in the Southwestern Atlantic (Brazil Basin) were identified.

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).

Tracing nearshore bottom currents with sea-bed drifters

Marine Geology, 1977
Abstract The experience acquired during 36 Woodhead drifter releases performed along the Tuscan coast is briefly reported. Without a costly apparatus, residual current patterns may be easily obtained with this method. Care should be taken, however, when sediment dispersal patterns are required, since weak currents which drag drifters slowly, displace

Current practice in designing bottom‐entering fermentor drives

Biotechnology and Bioengineering, 1983
AbstractTop entering drives have become almost traditional for fermentor applications, however bottom entering drives have distinct features that merit consideration. The prinicipal advantages of bottom drives are delineated and design criteria discussed. Illustrations based on experience with several hundred fermentors ranging in power from fractional

Bottom current measurements in the labrador sea

Journal of Geophysical Research, 1974
Twenty-one spot current meter measurements document a high-velocity bottom flow in places greater than 20 cm/s around the periphery of the Labrador basin and Greenland continental margin. These data are consistent with previous hydrographic and current measurements in the area.

Lock-exchange gravity currents over rough bottoms

Environmental Fluid Mechanics, 2016
In nature, density driven currents often flow over or within a bottom roughness: a sea breeze encountering tall buildings, a shallow flow encountering aquatic vegetation, or a dense oceanic current flowing over a rough bottom. Laboratory experiments investigating the mechanisms by which bottom roughness enhances or inhibits entrainment and dilution in ...
