Salt is power. The energy in places where salty ocean water and freshwater mingle could provide a massive source of renewable power. Stanford University researchers have developed an affordable, durab...
Over fifty years ago, Carl Eckart described the sequence of processes as a passive scalar is stirred and mixed in a turbulent flow (Eckart, 1948). At first, during the stirring phase, the variance of ...
Kelvin-Helmholtz (KH) instability, characterized by the distinctive
finite-amplitude billows it generates, is an important mechanism in the development
of turbulence in the stratified interior of ...
Frontogenesis and Frontal Progression of a Trapping-Generated Estuarine Convergence Front and Its Influence on Mixing and Stratification
Front Frontogenesis Trapping Convergence front Lateral circulation
<

Estuarine fronts are well known to influence transport of waterborne constituents such as phytoplankton and sediment, yet due to their ephemeral nature, capturing the physical driving mechanisms and t...
Wave-induced transport and vertical mixing of pelagic eggs and larvae
Wave-induced transport vertical mixing pelagic eggs and larvae
<
2014/7/10
The transport of pelagic plankton by wind-driven ocean currents and surface gravity waves is investigated for the example of Northeast Arctic cod eggs and larvae on the coast of northern Norway. Previ...
Oxygen in the deep Strait of Georgia, 1951–2009: The roles of mixing, deep-water renewal, and remineralization of organic carbon

since 1971 and now seasonally approaches thresholds of biological tolerance. The decline ha...
Shifts in limiting nutrients in an estuary caused by mixing and biological activity
limiting nutrients mixing biological activity
<
2014/4/8
Simple general equations are used to show that when riverine water mixes with seawater, the N : P ratio is a
nonlinear function of salinity. Thus, a shift in the limiting-nutrient status at a particu...
Mixing and stratification in lakes of varying horizontal length scales: Scaling arguments and energy partitioning
Mixing stratification varying horizontal length scales Scaling arguments energy partitioning
<
2014/4/17
This work analyzes the effects that changes in the surface area of stratified lakes have on the partitioning of energy among different pools, and, ultimately, on the strength of thermalstratification....
Turbulent mixing induced by nonlinear internal waves in Mono Lake, California

2014/4/17
Describing the spatial and temporal occurrence of turbulent mixing and the mechanisms of turbulence production are fundamental problems in physical limnology and oceanography. Here we present results ...
Mixing and its effects on biogeochemistry in the persistently stratified, deep, tropical Lake Matano, Indonesia
persistently stratified deep tropical Lake
<
2014/4/16
In the . 590-m deep, tropical Lake Matano (Indonesia), stratification is characterized by weak thermal
gradients (, 2uC per 500 m) and weak salinity gradients (, 0.14% per 500 m). These gradients per...
Effects of seasonal stratification on turbulent mixing in a hypereutrophic coastal lagoon
Effects of seasonal stratification turbulent mixing a hypereutrophic coastal lagoon
<
2014/4/16
Seasonal variations in vertical turbulent mixing rates, density structure, inorganic nutrient concentrations, and phytoplankton biomass were investigated in a shallow, tidally choked coastal lagoon. T...
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...

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...
