Micro- to Fine-Scale Chemical Gradients and Layers in Stratified Coastal Waters
Stratified Coastal Waters Chemical Gradients and Layers
2015/8/6
Models of biogeochemical dynamics and chemical variability in coastal waters have traditionally relied on the assumption that small-scale mixing processes are sufficiently strong and isotropic to rapi...
A Model for the Reflectance of Thin Layers, Fronts, and Internal Waves and Its Inversion
Thin Layers Fronts Internal Waves
2015/8/6
The interplay of physical and biogeochemical processes in the ocean can result in well-defined vertical gradients and maxima in biological properties. When these gradients and maxima exist near the se...
We are all familiar with the irregular profiles from modern, high resolution conductivity-temperature-depth profilers (commonly called CTDs) freely falling vertical profilers, and towed thermistor cha...
Thin Layers: Observations of Small-Scale Patterns and Processes in the Upper Ocean
Small-Scale Patterns Processes
2015/8/6
Fore decades, marine scientists have been asking questions about the response of planktonic distributions and processes to physical forcing across a range of temporal and spatial scales. The mismatch ...
Diffusive boundary layers do not limit the photosynthesis of the aquatic macrophyte Vallisneria americanaat moderate flows and saturating light levels
Diffusive boundary layers do not limit the photosynthesis the aquatic macrophyte Vallisneria americana moderate flows saturating light levels
2014/4/17
Hydrodynamic models of mass transport assume that diffusive processes next to the surface limit transport and that there are no biological and chemical processes that control the supply and demand of ...
Statistical measures of distribution patterns of silicon and calcium in marine sedimentary layers
Statistical measures distribution patterns silicon calcium marine sedimentary layers
2009/11/3
We analyze electron microscope X-ray spectroscopy data of recent supratidal marine sediments. Statistical measures are used to characterize the distribution of silicon and calcium in different layers ...

A Note on the Variability of the Heights of Tidal Benthic Boundary Layers.
Edge gradients provide evidence of ecological interactions in planktonic thin layers
Edge gradients provide ecological interactions
2014/4/18
Physical, optical, and acoustical data from Monterey Bay, California, USA, describing the distributions of
phytoplankton, zooplankton, and small fish as well as gradients in the physical habitat were...
Upwelling Layers in a Steady, Wind-Driven Stratified Ocean
Upwelling Layers Wind-Driven Stratified Ocean
2009/4/2
A theoretical study is made of a region of steady upwelling adjacent to the eastern boundary of a stratified ocean. A multi-layered structure is required to satisfy all the boundary conditions. The ve...
A Numerical Study of Time-Dependent Turbulent Ekman Layers over Horizontal and Sloping Bottoms
Time-Dependent Turbulent Ekman Layers Sloping Bottoms Horizontal
2009/3/24
A numerical study is made of a time-dependent turbulent Ekman bottom boundary layer. Parameters for the model were chosen to simulate conditions near the bottom of the Florida Current in the Straits o...
A Simulation of the Effects of Air-Sea Transfer Variability on the Structure of Marine Upper Layers
Air-Sea Transfer Variability Marine Upper Layers
2009/2/19
A rather simple one-dimensional unsteady model similar to Mellor and Durbin (1975) is used to study the effects of the time variability of meteorological inputs on the evolution of the thermal stratif...
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...
Mixed Layers and Fronts in Simple Ocean Circulation Models
Mixed Layers Simple Ocean Circulation Models Fronts
2009/2/9
A three-dimensional regime with a differentially heated mixed layer on top of an ideal fluid interior is considered in a situation which corresponds to the interior of the well-known wind-driven model...
Water-Mass Distributions at Intermediate Layers off the Somali Coast during the Onset of the Southwest Monsoon, 1979
Water-Mass Distributions Intermediate Layers Somali Coast
2009/2/8
Hydrographic observations at intermediate depth in the Somali Basin have been made during and after the transition from the northeast monsoon to the southwest monsoon, 1979. The data are discussed in ...
Stability of Free Surface Ekman Layers
Free Surface Ekman Layers wavenumbers α independent parameters
2009/2/5
The stability of free surface, laminar Ekman layers is examined for both the homogeneous and the two-layer case. The eigenvalues of the homogeneous case depend upon the wavenumbers α and &ggr; and the...
