Particle fluxes in the ocean

Sinking flux of particulate organic matter in the oceans - Nature

We formulate a mechanistic model for the depth-dependent, sinking, particulate mass flux constituted by a range of sinking, remineralizing particles.

Particle fluxes - AWI

The steady rain of settling particles throughout the ocean is the most efficient transport mechanism of many elements from the surface to the deep ocean and the ...

Particle fluxes to the interior of the Southern Ocean in the Western ...

A total of 174 sequential samples were recovered and analyzed to estimate fluxes of total mass (TMF), organic carbon, carbonate, biogenic silica, and lithogenic ...

Editorial: The oceanic particle flux and its cycling within the deep ...

This article is part of the Research Topic The Oceanic Particle Flux and its Cycling Within the Deep Water Column

9 Particle Fluxes in the Ocean and Implications for Sources and ...

CONCLUSIONS. Biological debris dominates the settling particle flux in most open ocean sites. This flux of material is not only an important mechanism for ...

A better insight into parameters that control particle flux in the ocean

For example, in the high-latitude Arctic Ocean, marine particles have high concentrations of ballasting minerals; this alone, however, cannot ...

The Flux of Particles to the Deep Sea: Methods, Measurements and ...

Before sediment traps were widely used, the determination of particle fluxes in the ocean centered on measuring the size and abundance of particles, estimat-.

Vertical flux of particles in the ocean - ScienceDirect.com

Most of the particle flux, the product of settling velocity and mass, is in the coarser size classes. Assumption of steady state requires aggregation of small ...

Deep ocean particle flux in the Northeast Atlantic over the past 30 ...

The time series of downward particle flux at 3000 m at the Porcupine Abyssal Plain Sustained Observatory (PAP-SO) in the Northeast Atlantic is ...

Particle flux in the oceans: Challenging the steady state assumption

We conclude that the steady state assumption leads to misinterpretation of particle flux profiles when input fluxes from the upper ocean vary on the order of ...

Particle fluxes by subtropical pelagic communities under ocean ...

Our findings suggest that carbon export by oligotrophic plankton communities is insensitive to OAE perturbations using a CO 2 pre-equilibrated approach.

Sinking flux of particulate organic matter in the oceans - PubMed

The sinking of organic particles produced in the upper sunlit layers of the ocean forms an important limb of the oceanic biological pump, ...

Particle Flux in the Deep Sargasso Sea - The Oceanography Society

Article Abstract. The Oceanic Flux Program (OFP) sediment trap time series, the longest running time series of its kind, has continuously ...

Biogenic sinking particle fluxes and sediment trap collection ...

Sinking particle sizes generally decreased between 100 and 335 m. Measured 234Th fluxes were smaller than water column 234Th fluxes by a factor ...

Particle Fluxes – GEOTRACES

In the ocean, the residence time of mercury (Hg), is largely driven by two removal mechanisms: evasion to the atmosphere and downward export flux with settling ...

(PDF) Particle flux in the oceans: Challenging the steady state ...

We conclude that the steady state assumption leads to misinterpretation of particle flux profiles when input fluxes from the upper ocean vary on the order of ...

Rapid coupling of sinking particle fluxes between surface and deep ...

SETTLING particles are thought to be responsible for much of the transport of mass and energy from the upper ocean to the sea floor.

Particle fluxes in the ocean: Comparison of sediment trap data with ...

The model is fitted to the propertyconcentrations by systematically varying circulation, air-sea fluxes,export production and remineralization rates of ...

Downward particle flux and carbon export in the Beaufort Sea, Arctic ...

Besides analyses of C and N, the collected material was investigated for pigments, phyto- and microzooplankton, faecal pellets and swimmers. The measured fluxes ...

Particulate fluxes of carbonate and organic carbon in the ocean. Is ...

The particulate fluxes of carbonate carbon and organic carbon observed in various oceans have been summarized in this paper and discussed with special ...
