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 ...

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

Monitoring of the carbon footprint of road freight transport activities

Monitoring of the carbon footprint of road freight transport activities, 2023
The article analyzes the process of monitoring the carbon footprint of road freight transport. The significance of the influence of road transport on climate warming is revealed. In order to select the most appropriate method for calculating pollution with greenhouse gases, the methodology for calculating pollution is analyzed.

Transport Activity of the High-affinity Monocarboxylate Transporter MCT2 Is Enhanced by Extracellular Carbonic Anhydrase IV but Not by Intracellular Carbonic Anhydrase II [PDF]

Journal of Biological Chemistry, 2011
The ubiquitous enzyme carbonic anhydrase isoform II (CAII) has been shown to enhance transport activity of the proton-coupled monocarboxylate transporters MCT1 and MCT4 in a non-catalytic manner. In this study, we investigated the role of cytosolic CAII and of the extracellular, membrane-bound CA isoform IV (CAIV) on the lactate transport activity of ...
