Particle Flux in the Deep Sargasso Sea:The 35-Year Oceanic Flux Program Time Series
Particle Flux Deep Sargasso Sea 35-Year Oceanic Flux Program Time Series
2015/7/17
The Oceanic Flux Program (OFP) sediment trap time series, the longest running time series of its kind, has continuously measured particle fluxes in the deep Sargasso Sea since 1978. OFP results provid...
Midwater zooplankton and suspended particle dynamics in the North Pacific Subtropical Gyre: A stable isotope perspective
North Pacific Subtropical Gyre Midwater zooplankton
2014/4/2
We used amino acid (AA) compound-specific isotope analysis (d15NAA and d13
CAA values) of midwater
zooplankton and suspended particles to examine their dynamics in the mesopelagic zone. Suspended pa...
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
2014/4/2
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...
Variability in optical particle backscattering in contrasting bio-optical oceanic regimes
Variability contrasting bio-optical oceanic
2014/4/8
Variability in the optical particle backscattering coefficient (bbp) is investigated in oceanic waters from two
sites, namely the BOUe′e pour l’acquiSition d’une Se′rie Optique a` Long termE site in ...
Variations in the optical properties of a particle suspension associated with viral infection of marine bacteria
Variations particle suspension associated marine bacteria
2014/4/17
A laboratory experiment was conducted to examine the temporal dynamics of the particle size distribution
(PSD) and associated optical variability caused by viral infection of marine heterotrophic bac...
Particle dispersal due to interplay of motions in the surface layer of a small reservoir
surface layer reservoir Particle dispersal
2014/4/16
Horizontal dispersion mechanisms must be well defined in order to determine the origin and fate of
heterogeneous distributions of biogeochemical material. Here data from an intensive field campaign i...
Sedimentation of acantharian cysts in the Iceland Basin: Strontium as a ballast for deep ocean particle flux, and implications for acantharian reproductive strategies
acantharian cysts a ballast for deep ocean particl
2014/4/16
Acantharian cysts were discovered in sediment trap samples from spring 2007 at 2000 m in the Iceland Basin.
Although these single-celled organisms contribute to particulate organic matter flux in the...
Numerical Simulation of Dam Breaking Using Smoothed Particle Hydrodynamics and Viscosity Behavior
meshless method smoothed particle hydrodynamics (SPH) dam breaking free surface flow
2011/9/9
Smoothed particle hydrodynamics (SPH) is a Lagrangian meshless particle method. It is one of the best method for simulating violent free surface flows in fluids and solving large fluid deformations. D...

through the ocean’s ‘‘biological pump.’’ Much of this particle flux is remineralized in...
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 ...
Potential Vorticity Balances and Horizontal Divergence along Particle Trajectories in Gulf Stream Meanders East of Cape Hatteras
Potential Vorticity Balances Horizontal Divergence Particle Trajectories Gulf Stream
2009/1/5
Trajectories of 37 isopycnal RAFOS floats launched in the Gulf Stream off Cape Hatteras have been analyzed to examine the dynamics of meanders from a Lagrangian viewpoint. Using the float data in conj...
A one-dimensional model of baroclinic instability is used to reconcile two differing interpretations on why neutrally buoyant floats cross the Gulf Stream more readily at subthermocline depths. The st...
A Closer Look at Particle Exchange in the Gulf Stream
Particle Exchange Gulf Stream eddy-resolving GCM
2008/12/16
The trajectories of 95 isopycnal floats deployed in the Gulf Stream in the last decade have shown that a substantial amount of particle exchange takes place between the Gulf Stream and the surrounding...
