We examined the dispersal of larvae (glochidia) of a common unionid mussel species, Actinonaias ligamentina,
which need to attach to a host fish in order to develop into juveniles, in a lowland river...
Internal Wave Dispersion Calculated Using the Thomson-Haskell Method
Internal Wave Thomson-Haskell Method
2009/3/24
The dispersion and amplitude characteristics of internal wave motion are determined by a matrix method which lends itself readily to computer analysis. A layered density structure may be chosen to fit...
Shear dispersion results from vertical shear of horizontal velocity and vertical mixing, features which cannot be included explicitly in one-layer, vertically integrated models. The parametric descrip...
The Influence of the Directional Energy Distribution on the Nonlinear Dispersion Relation in a Random Gravity Wave Field
Directional Energy Distribution Nonlinear Dispersion Relation Random Gravity Wave Field
2009/3/7
The influence of the directional distribution of wave energy on the dispersion relation is calculated numerically using various directional wave spectrum models. The results indicate that the dispersi...
The seaward transport of salt by river discharge through an estuary is balanced under steady conditions by landward dispersion effected by various physical mixing processes. Observations of current an...
Shear-Flow Dispersion, Internal Waves and Horizontal Mixing in the Ocean
Shear-Flow Dispersion Horizontal Mixing Internal Waves
2009/2/7
wave are discussed. Our goal is to develop intuition about the role of such currents in horizontal ocean mixing through the mechanism of shear dispersion. The analysis suggests simple parameterization...
On the Influence of Stratification and Continental Shelf and Slope Topography on the Dispersion of Subinertial Coastally Trapped Waves
Continental Shelf Slope Topography Subinertial Coastally Trapped Waves
2009/2/6
The behavior of subinertial, coastally trapped free waves in a continuously stratified ocean is examined using a two-slope topography in which the continental shelf and slope are each represented by a...
Benthic Observations on the Madeira Abyssal Plain：Currents and Dispersion
Madeira Abyssal Plain Currents Dispersion
2009/2/6
An experiment to measure near-bottom currents on the Madeira Abyssal Plain is described. The moorings placed near 33°N, 22°W were separated by 5–40 km with instruments at 10, 100 and 600 m above the b...
A dye dispersion experiment was performed in September, 1979, in the open ocean approximately 180 km off the east coast of Florida. An initially vertical sheet of dye extending from about 60 to 100 me...
Dispersion of Marked Fluid Elements in a Turbulent Ekman Layer
stochastic model Fluid Elements Turbulent Ekman Layer
2009/1/13
A stochastic model is derived for studying shear-dispersion in a horizontally homogeneous, turbulent Ekman layer that is evolving in time. It is based on a one-dimensional model including an advanced ...
The Roles of Langmuir Circulations in the Dispersion of Surface Tracers
Langmuir Circulations Dispersion of Surface Tracers
2009/1/6
A hierarchy of theoretical and numerical models for the dispersion of discrete floating tracers on lakes and oceans is presented. Central to these models is the role of Langmuir circulations, which co...
Particle Dispersion and Mixing of Conservative Properties in an Eddy-Resolving Model
Particle Dispersion Eddy-Resolving Model Conservative Properties
2009/1/5
We examine the diffusive behavior of the flow field in an eddy-resolving, primitive equation circulation model. Analysis of fluid particle trajectories illustrates the transport mechanisms, which are ...

2008/12/17
The dispersion of heavy suspensions in a wave boundary layer over a nonerodible bed is examined theoretically. Focusing attention on the horizontal variation of the ambient wave pattern, an effective ...
The dispersion of a tracer by a two-dimensional gyre circulation is studied using simple numerical models. Two approaches are taken: a random walk model formulated in a streamline coordinate system an...
