This research aims to analyze the dynamics of dissolved organic matter (DOM) at the sediment-water interface and how it influences global carbon cycles.
Conducted quantitative and molecular analyses of porewater DOM in the German Bight, North Sea.
Utilized carbon isotope analysis (δ13C and F14C) to evaluate DOM composition and production.
Applied negative-pressure techniques for accurate diffusive DOC flux estimates.
Estimated diffusive DOC fluxes: 0.48 mol C m−2 yr−1 for shelf sediments and 0.12 mol C m−2 yr−1 for slope/deep-sea sediments.
Porewater DOM dynamics are influenced by sediment transport and diagenetic pathways, affecting global carbon cycling.
Younger, reactive compounds are exported, significantly impacting the marine DOM reservoir.
