Microscopy and DNA‐based characterization of sinking particles at the Bermuda Atlantic Time‐series Study station point to zooplankton mediation of particle flux

Limnology and Oceanography, 2021
Plankton‐derived, microscopic, and macroscopic sinking aggregates constitute most of the particulate organic carbon (POC) flux in the oceans. While the flux of particulate organic matter and associated elements has been quantified at the Bermuda Atlantic

Flux boundary conditions in particle simulations

Physical Review E, 2005
Flux boundary conditions are interesting in a number of contexts ranging from multiscale simulations to simulations of molecular hydrodynamics in nanoscale systems. Here we introduce, analyze, and test a general scheme to impose boundary conditions that simultaneously control the momentum and energy flux into open particle systems The scheme is shown ...

Flux-matching theory of particle charging

Physical Review E, 2004
A new flux-matching theory is formulated and applied to the study of particle charging by ions. Assuming that the ion-particle interaction includes the Coulomb + polarization forces the collisionless kinetic equation is solved and the ion concentration profile in the free-molecule zone (at the distances less than the ion mean free path) is found.

Microcantilever charged-particle flux detector

Review of Scientific Instruments, 2002
A micromechanical sensor for charged-particle flux detection utilizing the extreme force sensitivity of microcantilevers is demonstrated with alpha particles. The latter create a charge buildup on an electrically isolated collection plate, a metallic sphere. The cantilever detector measures the electric field emanating from the charge collection sphere

Observations of radially elongated particle flux induced by streamer in a linear magnetized plasma

Physics of Plasmas, 2019
The streamer-driven particle flux is evaluated experimentally in a linear cylindrical plasma. The streamers, a radially elongated and azimuthally localized structure created in turbulent plasma, really induce ballistic transport, and directly connect the

Modelling Particle Fluxes

1993
Marine particles play an important rôle in the chemistry of the oceans, not only because they provide sources of, and sinks for, solutes, but also, and especially, because they move relative to water. Examples of the resulting fluxes can be seen in the vertical transport of organic carbon and nitrogen, calcium carbonate, or trace metals. The components
