Investigating the kinetics of marine and terrestrial organic carbon incorporation and degradation in coastal bulk sediment and water settings through isotopic lenses

Author(s): Mirzaei Y; Gélinas Y;

Coastal sediments are the main deposition center for allochthonous and autochthonous organic carbon (OC). The discharge of terrestrial biomass, anthropogenic activities, oceanic primary productivity, and natural events contribute to this carbon pool. The OC ...

Organic matter preservation through complexation with iron minerals in two basins of a dimictic boreal lake with contrasting deep water redox regimes

Author(s): Joshani A; Mirzaei Y; Barber A; Balind K; Gobeil C; Gélinas Y;

The biogeochemical cycles of iron and organic carbon (OC) are closely interconnected in terrestrial and aquatic systems. In ocean waters, the concentration of reactive Fe is tightly controlled by soluble organic ligands. In soils, Fe stabilizes OC by formin ...

Using 13C enriched acetate in isotope labelling incubation experiments: a note of caution

Author(s): Leone F; Imfeld A; Mirzaei Y; Gélinas Y;

Vapour-phase fumigation with HCl is routinely used to remove inorganic carbon in preparation for the measurement of the concentration and d13C value of organic carbon in a sample using elemental analysis coupled to an isotope ratio mass spectrometer. Acidif ...
