ESR 9 – Project description
Studying the effect of Fe addition to sediments on the sedimentary biogeochemical processes
ESR 9: Karel As
Project description:The project of ESR 9 aims to determine the dynamics of major biogeochemical cycles (C,N,Fe,S) and solute fluxes studying pore-water composition, solid phase speciation and turnover rates (e. g. sulphate reduction rates) in P-rich aquatic systems. The effect of biogeochemical cycles on the mobilisation of P considering will be numerically simulated using an early diagenetic modelling approach emphasizing the role of iron hydroxides as a geochemical barrier.
