Biological Responses in a Dynamic Buoyant River Plume
Biological Responses Dynamic Buoyant River Plume
2015/7/22
Buoyant river plumes are highly dynamic and often characterized by marked physical and chemical gradients that interact to drive biological responses. For example, interactions among factors resulting...
Turbulence Observations in a Buoyant Hydrothermal Plume on the East Pacific Rise
Turbulence Observations Buoyant Hydrothermal Plume East Pacific Rise
2015/7/14
Hot vent fluid enters the ocean at high-temperature hydrothermal vents, also known as black smokers. Because of the large temperature difference between the vent fluid and oceanic near-bottom waters, ...
Flow-induced reconfiguration of buoyant and flexible aquatic vegetation
Flow-induced reconfiguration flexible aquatic vegetation
2014/4/4
Plant posture can play a key role in the health of aquatic vegetation, by setting drag, controlling light
availability, and mediating the exchange of nutrients and oxygen. We study the flow-induced r...
Internal Wave Spectra at the Buoyant and Inertial Frequencies
Internal Wave Spectra Buoyant Inertial Frequencies
2009/2/19
Spectra of the vertical displacement (potential energy) have been observed to be only slightly enhanced at the buoyancy frequency ω = N, whereas spectra of horizontal velocity u, v (kinetic energy) ar...
Vertical Heat-Flux Measurements from a Neutrally Buoyant Float
Neutrally Buoyant Float net heat flux near-inertial critical layer
2008/12/10
A neutrally buoyant float instrumented to measure 1–5 m shear and stratification was deployed for ten days in a near-inertial critical layer at the base of a warm-core ring. Vertical velocity and temp...
A Simple Theory for the Fate of Buoyant Coastal Discharges
Buoyant Coastal Discharges buoyant fluid
2008/11/24
A simple theory that predicts the vertical structure and offshore spreading of a localized buoyant inflow onto a continental shelf is formulated. The theory is based on two competing mechanisms that m...
Numerical Simulations of Buoyant Ekman Layers in the Presence of Variable Stratification. Part I: Constant Interior Forcing
Numerical Simulations Buoyant Ekman Layers Variable Stratification Interior Forcing
2008/7/30
Two-dimensional numerical simulations of the turbulent buoyant Ekman layer in the presence of variable stratification help explain a transport mechanism for the detachment of the boundary layer flow a...
Penetration of Buoyant Coastal Discharge onto the Continental Shelf: A Numerical Model Experiment
Buoyant Coastal Continental Shelf A Numerical Model
2008/7/21
Plumes of buoyant water produced by inflow from rivers and estuaries are common on the continental shelf. Typically they turn anticyclonically to flow alongshelf as buoyancy-driven coastal currents. D...
Boundary Layer Control of Buoyant Coastal Currents and the Establishment of a Shelfbreak Front
Boundary Layer Control of Buoyant Coastal Currents and the Establishment of a Shelfbreak Front
2008/7/4
The bottom boundary layer exerts a powerful control over buoyant coastal currents that contact the bottom, providing a mechanism for trapping density fronts along isobaths. Recent observations suggest...
Scaling Analysis for the Interaction between a Buoyant Coastal Current and the Continental Shelf: Experiments and Observations
Buoyant Coastal Current Continental Shelf
2008/6/23
This paper addresses how the geometrical parameters (ambient ocean depth, H; bottom slope, α) of coastal bathymetry affect the evolution of buoyant coastal currents flowing over a sloping continental ...

Simple mixing criteria for the growth of negatively buoyant phytoplankton
mixing criteria negatively buoyant phytoplankton
2014/5/20
Phytoplankton population dynamics are controlled by the relative rather than absolute timescales of mixing, growth, and loss processes such as sedimentation, grazing, and so on. Here, the vertical dis...
Observations of a negatively buoyant river plume in a large lake
Observations of a negatively buoyant river plume large lake
2014/5/20
Although seldom studied, negatively buoyant river plumes may be common within large lakes, especially during spring when lake and river waters are near the temperature of maximum fresh water density (...
