BOOK REVIEW——Estuaries: Dynamics, Mixing, Sedimentation and Morphology
Physical oceanography dynamics mixing sedimentation
2015/7/6
For instructors or students of physical oceanography at the graduate level, choosing a textbook is a pleasant exercise and often a matter of taste rather than necessity when it comes to open-ocean pro...
Eddy growth and mixing in mesoscale oceanographic flows
Eddy growth and mixing mesoscale oceanographic flows
2009/11/13
We study the relation between changes in the Eulerian topology of a two dimensional flow and the mixing of fluid particles between qualitatively different regions of the flow. In general time dependen...
Surface mixing and biological activity in the four Eastern Boundary Upwelling Systems
Surface mixing biological activity four Eastern Boundary Upwelling Systems
2009/10/30
Eastern Boundary Upwelling Systems (EBUS) are characterized by a high productivity of plankton associated with large commercial fisheries, thus playing key biological and socio-economical roles. Since...
Theoretical Aspects of Wind-Driven Currents in a Sea or Lake of Variable Depth with No Horizontal Mixing
Wind-Driven Currents Variable Depth with No Horizontal Mixing
2009/4/3
Steady-state wind-driven circulations in a basin of variable depth, with only vertical turbulent mixing, are considered. The geostrophic flow away from the coast is determined for an arbitrary bottom ...
Vertical mixing in the ocean affects the formation of water masses as well as the vertical distribution of nutrients and dissolved substances. This study is an investigation of the vertical mixing in ...
A Possible Mechanism for Boundary Layer Mixing and Layer Formation in a Stratified Fluid
Possible Mechanism Layer Formation Boundary Layer Mixing Stratified Fluid
2009/3/9
A plate tilted at 42° from the horizontal is oscillated along its length with frequency ω and amplitude a in a linearly stratified fluid (salt water) of kinematic viscosity ν. If the Reynolds number R...
The Role of Surface Mixing in the Seasonal Variation of the Ocean Thermal Structure
Surface Mixing Ocean Thermal Structure Seasonal Variation
2009/3/7
The role of surface-generated mixing in determining the seasonal variation of the ocean thermal structure is investigated using a one-dimensional numerical model. The model contains vertical eddy diff...
Variations in the Intensity of Small-Scale Mixing in the Main Thermocline
Small-Scale Mixing Main Thermocline
2009/3/7
Three cruises to the same site in the central North Pacific (28°N, 155°W) found naked differences in the levels of small-scale turbulent activity as indicated by spectra of temperature profiles. Consi...
Measurements made in Cambridge Bay, N.W.T., during the winter show that the breaking of internal waves on the shore influences downward salt transport from the homogeneous surface layer produced by sa...
The Langmuir Circulation Instability as a Mixing Mechanism in the Upper Ocean
Langmuir Circulation Instability Mixing Mechanism Upper Ocean
2009/2/16
A numerical study of the fully nonlinear instability of the ocean to Langmuir circulations is reported. The extended Craik-Leibovich theory is used to compute the development of a mixed layer in an oc...
Signatures of Mixing from the Bermuda Slope, the Sargasso Sea and the Gulf Stream
Mixing Sargasso Sea Bermuda Slope Gulf Stream
2009/2/16
Nearly simultaneous profiles of temperature microstructure and velocity shear were made adjacent to the island of Bermuda. Profiles with elevated microstructure levels were found in close association ...
Observations of turbulent energy dissipation rate in the deep surface mixed layer at a mid-Sargasso site are presented: two occupations of this site include a large range of local meteorological forc...
In this paper a mechanism is proposed which could be responsible for the formation of sharp horizontal density gradients such as those observed in shallow seas, from fluid which initially has weak hor...
The Role of Wind-Generated Mixing in Coastal Upwelling
Wind-Generated Mixing Coastal Upwelling
2009/2/10
A simple parameterization of mixing processes originally developed by Kraus and Turner (1967) is included in a two-dimensional, two-layer theory of wind-driven coastal upwelling. Mixed-layer deepening...
Wind Mixing and Restratification in a Lake near the Temperature of Maximum Density
Wind Mixing Temperature Maximum Density
2009/2/10
The cooling of a freshwater take provides an opportunity for studying wind mixing and restratification under the peculiar conditions associated with a density maximum. The concepts are explored using ...
