USING ISOLATION BY DISTANCE AND EFFECTIVE DENSITY TO ESTIMATE DISPERSAL SCALES IN ANEMONEFISH
Amphiprion clarkii continuous population
2015/12/11
Robust estimates of dispersal are critical for understanding population dynamics and local adaptation, as well as for successful
spatial management. Genetic isolation by distance patterns hold clues ...
Ocean warming contributes to global mean sea level rise by reducing the density of seawater, thus increasing its volume. Freshening of seawater also reduces its density, and this effect contributes to...
In situ variability of mass-specific beam attenuation and backscattering of marine particles with respect to particle size, density, and composition
In situ variability mass-specific beam attenuation backscattering marine particles respect to particle size density and composition
2012/4/2
This study analyzes relationships between concentration of suspended particles represented by dry mass,[SPM], or area, [AC], and optical properties including particulate beam attenuation (cp), side sc...
No empirical evidence for community-wide top-down control of prey fish density and size by fish predators in lakes
No empirical evidence community-wide top-down control prey fish density size by fish predators in lakes
2010/4/16
I tested relationships between fish predator and prey densities or size across 66 lakes of the European temperate zone, covering mean depths between 1 and 22 m and a phytoplankton biomass range betwee...
Reflection of Internal Gravity Waves by small Density Variations
Internal Gravity Waves small Density Variations
2009/4/3
The propagation of small-amplitude internal gravity waves through a finite layer of varying Brunt-Väisälä frequency is analyzed. A two-scale analysis is used and it is shown that the am...
Bispectra and Cross-Bispectra of Temperature, Salinity, Sound Velocity and Density Fluctuations with Depth off Northeastern Japan
Temperature Salinity Sound Velocity Density Fluctuations
2009/4/2
Off northeastern Japan, depth profiles of temperature, salinity, sound velocity and density show considerable structure between 30 and 240 m. The structure is asymmetric with respect to the mean and t...
On North Pacific Temperature, Salinity, Sound Velocity and Density Fronts and their Relation to the Wind and Energy Flux Fields
North Pacific Temperature Sound Velocity Salinity Density Fronts Energy Flux Fields
2009/3/24
The main oceanic fronts of the North Pacific are investigated and the principal frontogenetic processes described. Fronts are features of the upper ocean and occur near mass transport and energy flux ...
Internal Wave Reflection by a Velocity Shear and Density Anomaly
Internal Wave Velocity Shear Density Anomaly
2009/3/24
Numerical solutions are obtained for the reflection of upward propagating internal waves by simple pycnocline and current shear models. Results for a simple monotonic shear and a velocity jet, with an...
Deep density-depth curves often show faint curvature reversals, stability maxima etc. Relationships between these features and the field of motion are explored here, in reference to the South Pacific,...
The Circulation Dynamics and Thermodynamics of Upper Ocean Density Fronts
Circulation Dynamics Thermodynamics Upper Ocean Density Fronts
2009/2/19
This paper extends a previous hydrodynamic circulation model of established, persistent upper ocean density fronts by including a thermodynamic or buoyancy equation in the integral treatment. An analy...
On the Stability of a Fluid with Specialized Density Stratification. Part II：Mixed Baroclinic-Barotropic Instability with Application to the Northeast Pacific
Density Stratification Mixed Baroclinic-Barotropic Instability Northeast Pacific
2009/2/18
Low-frequency motions (0.25 cpd) have recently been observed in Juan de Fuca Strait. The three-layer model developed in Part I of this paper is used to show that some of this activity may be due to an...
On the Stability of a Fluid with Specialized Density Stratification. Part I：Baroclinic Instability and Constant Bottom Slope
Specialized Density Stratification Baroclinic Instability Constant Bottom Slope
2009/2/16
A three-layer model is used to study the stability of large-scale oceanic zonal flows over topography. The mean density profile employed has upper and lower layers of constant densities ρ1* and ρ3*, r...
Coupling of Internal Wave Motion with Entrainment at the Density Interface of a Two-Layer Lake
Internal Wave Motion Two-Layer Lake Density Interface
2009/2/16
A solution is presented to the problem of a two-layer rectangular basin subject to a suddenly applied, uniform wind stress; Coriolis effects are ignored. The solution is obtained for the case in which...
A Spin-Up Model as a Diagnostic Tool for Interpretation of Current and Density Measurements on the Continental Shelf of the Pacific Northwest
Spin-Up Model Pacific Northwest Continental Shelf Diagnostic Tool
2009/2/16
The primary goal of this paper is to prescribe the practical limitations of the two-dimensional, baroclinic, time-dependent model of Hamilton and Rattray (1978) for the Oregon-Washington continental s...
