Transport and reduction of nitrate in clayey till underneath forest and arable land. [PDF]

, 2004
Transport and reduction of nitrate in a typically macroporous clayey till were examined at variable flow rate and nitrate flux. The experiments were carried out using saturated, large diameter (0.5 m), undisturbed soil columns (LUC), from a forest and ...

The Importance of Mesozooplankton Diel Vertical Migration for Sustaining a Mesopelagic Food Web

Frontiers in Marine Science, 2019
We used extensive ecological and biogeochemical measurements obtained from quasi-Lagrangian experiments during two California Current Ecosystem Long-Term Ecosystem Research cruises to analyze carbon fluxes between the epipelagic and mesopelagic zones ...

Influence of hydrodynamic processes on the fate of sedimentary organic matter on continental margins [PDF]

, 2018
Understanding the effects of hydrodynamic forcing on organic matter (OM) composition is important for assessment of organic carbon (OC) burial in marginal seas on regional and global scales.

Preservation of organic carbon during active fluvial transport and particle abrasion [PDF]

Geology, 2019
Abstract Oxidation of particulate organic carbon (POC) during fluvial transit releases CO2 to the atmosphere and can influence global climate. Field data show large POC oxidation fluxes in lowland rivers; however, it is unclear if POC losses occur predominantly during in-river transport, where POC is in continual motion within an aerated

Modeling the contribution of micronekton diel vertical migrations to carbon export in the mesopelagic zone [PDF]

Biogeosciences
Micronekton plays a significant but often overlooked role in carbon transport within the ocean. Using a one-dimensional trait-based model, we simulated the diel vertical migrations (DVMs) of micronekton and their carbon production through respiration ...

Charge dependence of neoclassical and turbulent transport of light impurities on MAST [PDF]

, 2015
Carbon and nitrogen impurity transport coefficients are determined from gas puff experiments carried out during repeat L-mode discharges on the Mega-Amp Spherical Tokamak (MAST) and compared against a previous analysis of helium impurity transport on ...

Supercapacitor Performance of Nickel-Cobalt Sulfide Nanotubes Decorated Using Ni Co-Layered Double Hydroxide Nanosheets Grown in Situ on Ni Foam [PDF]

, 2020
In this study, to fabricate a non-binder electrode, we grew nickel-cobalt sulfide (NCS) nanotubes (NTs) on a Ni foam substrate using a hydrothermal method through a two-step approach, namely in situ growth and an anion-exchange reaction.
