Energy Flux and Particle Flux in Steady-state Solutions of Nuclear Star Clusters

open access: yesThe Astrophysical Journal, 2023
We examine the effects of two-body interactions in a nuclear star cluster surrounding a supermassive black hole. We evaluate the energy flux, analogously to the particle flux calculation of Bahcall and Wolf.

Biological–physical oceanographic coupling influencing particulate organic matter in the South Yellow Sea

open access: yesFrontiers in Marine Science, 2022
Using total suspended matter (TSM), particulate organic carbon (POC), and particulate nitrogen data, this study investigated the potential vertical POC flux and transport in the South Yellow Sea (SYS). The biogenic production and resuspension fraction (i.

Seasonal Variability in Near-bed Environmental Conditions in the Vazella pourtalesii Glass Sponge Grounds of the Scotian Shelf

open access: yesFrontiers in Marine Science, 2021
The Scotian Shelf harbors unique aggregations of the glass sponge Vazella pourtalesii that provides an important habitat for benthic and pelagic fauna. Recent studies have shown that these sponge grounds have persisted in the face of strong inter-annual ...

Autonomous, high-resolution observations of particle flux in the oligotrophic ocean [PDF]

open access: yesBiogeosciences, 2013
Observational gaps limit our understanding of particle flux attenuation through the upper mesopelagic because available measurements (sediment traps and radiochemical tracers) have limited temporal resolution, are labor-intensive, and require ship ...

Modeling on Effect of Particle Sediment on Fluid Flow and Heat Transfer of Solid–Fluid Suspension

open access: yesEnergies, 2021
A two-way coupling particle flux model is proposed for studying the multi-component solid–fluid suspension. The suspension mixture is treated as a non-linear single-phase fluid and the migration of the solid particles is modeled by a particle flux ...

Measurements and modeling of type-I and type-II ELMs heat flux to the DIII-D divertor

open access: yesNuclear Fusion, 2023
Type-I and type-II edge-localized-modes (ELMs) heat flux profiles measured at the DIII-D divertor feature a peak in the vicinity of the strike-point and a plateau in the scrape-off-layer (SOL), which extends to the first wall.

Influence of atmospheric dust deposition on sinking particle flux in the northwest Pacific

open access: yesFrontiers in Marine Science, 2023
We examined the flux and composition of sinking particles collected at a water depth of 800 m in the northwest Pacific from November 2017 to August 2018 to assess the impact of dust deposition on organic carbon export.

Removing Orbital Variations From Low Altitude Particle Data: Method and Application

open access: yesSpace Weather, 2021
Particle flux measurements from polar orbiting low altitude satellites provide a view of the near Earth radiation environment that is extremely valuable for science as well as space weather monitoring. Unlike, geosynchronous satellites that sample only a

Temporal variability of particle flux and its components in the Gotland Basin, eastern Baltic Sea

open access: yesFrontiers in Earth Science, 2023
Sinking particles were studied by analyzing samples collected in a sediment trap at 180 m depth in the Gotland Basin, eastern Baltic Sea between 1999 and 2020.

Particle Fluxes at the Australian Southern Ocean Time Series (SOTS) Achieve Organic Carbon Sequestration at Rates Close to the Global Median, Are Dominated by Biogenic Carbonates, and Show No Temporal Trends Over 20-Years

open access: yesFrontiers in Earth Science, 2020
Particle fluxes at the Southern Ocean time series (SOTS) site in the Subantarctic Zone (SAZ) south of Australia (∼47°S, ∼142°E, 4600 m water depth) were collected from 1997 – 2017 using moored sediment traps at nominal depths of 1000, 2000, and 3800 m ...
