Advances in Marine Ecosystem Dynamics from US GLOBEC: The Horizontal-Advection Bottom-up Forcing Paradigm
Global ocean ecosystem dynamics ecosystem climate Marine ecosystems
2015/7/16
A primary focus of the US Global Ocean Ecosystem Dynamics (GLOBEC) program was to identify the mechanisms of ecosystem response to large-scale climate forcing under the assumption that bottom-up forci...
Stratification and horizontal exchange in Lake Victoria, East Africa
Lake Victoria East Africa
2014/11/28
We characterize stratification patterns over diel, seasonal, and annual time scales in inshore and offshore
regions of Lake Victoria, East Africa; determine conditions leading to horizontal exchanges...
The asymmetry of the underwater horizontal light field and its implications for mirror-based camouflage in silvery pelagic fish
horizontal light field silvery pelagic fish
2014/11/28
Many pelagic species, particularly teleost fish, have silvered lateral surfaces that are thought to primarily serve
as a form of camouflage. The underlying argument is that the underwater light field...

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....

Numerical Modeling for the Effect of a 2-D Seafloor Trench on Sea-Bottom EM Measurements Using Horizontal Electric Dipole Sources.
Numerical Model of Convection Driven by a Surface Stress and Non-Uniform Horizontal Heating
Convection Driven Surface Stress Non-Uniform Horizontal Heating
2009/4/3
This paper examines the two-dimensional convective motion of a nonrotating incompressible Boussinesq fluid heated non-uniformly from below. The fluid container is rectangular; the side and top boundar...
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 ...
Horizontal Coherence of Temperature Microstructure
Horizontal Coherence Temperature Microstructure
2009/3/24
Temperature gradient records from vertical lowerings of an array of four thermometers are used to trace microstructure features horizontally over a distance of 46 cm. Identifiable features are found t...
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 Determination of Horizontal Divergence in the Gulf Stream off Cape Lookout
Horizontal Divergence Gulf Stream off Cape Lookout
2009/3/9
A horizontal divergence of 2×10−5 sec−1 was determined by tracking three shallow drogues in the speed axis of the Gulf Stream. Concurrent bathythermograph soundings along a drogue track su...

2009/3/7
A theoretical model of the spatial spectrum of horizontally distributed thermal microstructure is developed for anisotropic turbulence. A two-term power law representation is obtained for the horizont...
Horizontal Diffusion Characteristics in Lake Ontario
Horizontal Diffusion Characteristics Lake Ontario
2009/3/7
Experimental data on the diffusion of fluorescent dye patches were obtained in Lake Ontario, to study large-scale horizontal diffusion characteristics. In each experiment, a slug of water-soluble rhod...
Horizontal Divergence and Vorticity Estimates from Velocity and Temperature Measurements in the MODE Region
Horizontal Divergence MODE Region Vorticity Estimates
2009/3/7
Estimates of horizontal derivatives of velocity made by differencing velocity measurements are used to show that the observed velocity field due to low-frequency mesoscale motions during the prelimina...
