In terrestrial and aquatic environments, the individual and coupled reactions of iron (Fe), sulfur (S) and carbon (C) are controlled by a complex interplay between hydrological, geochemical, and microbial processes. Due to their reactivity, Fe, S, and C species play a key role in maintaining important ecosystem services, such as the removal of environmental pollutants, and the supply of carbon, nitrogen as well as other essential nutrients. This session welcomes contributions from laboratory experiments, field studies, and theoretical approaches that improve our understanding of the biogeochemical cycling of Fe, S and C, including their impact on nutrient and contaminant dynamics. We especially encourage contributions that use multidisciplinary approaches and novel analytical methods to explore biogeochemical processes across multiple spatial and temporal scales.
