 Project objective

Earth’s geochemical evolution was shaped by an enormous microbial metabolic diversity. One of the urgent scientific grand challenges is to decipher the key geochemical pathways involved in those 4 Gy of evolution, with the ultimate aim to obtain a truly predictive understanding of the response of the Earth System to global change. Rapid advances in geochemistry and microbiology have revealed the unique and critical role of sharp redox transitions in marine environments as prime sites for the removal of toxic ammonium and the greenhouse gas methane. Yet, the redox reactions, microbial players, and key controls remain largely unexplored. Our ERC synergy project MARIX will unite the complementary expertise required to gain a fundamental and mechanistic understanding of the geochemistry of these redox zones and the complex in-situ microbial interactions that together strongly impact our environment. By combining highly innovative fieldwork, cutting-edge laboratory experiments and state-of-the-art modeling for a range of carefully selected and representative coastal ecosystems we will: 1. Unravel the geochemistry and novel microbial pathways that remove methane and ammonium through oxidation with metal-oxides. 2. Determine the impact of the novel microbial pathways of methane and ammonium oxidation on the dynamics of nutrients, oxygen and other key elements. 3. Develop innovative gene-centric biogeochemical models for coastal sediments and overlying waters, to improve projections of the impacts of eutrophication and climate change. MARIX will bring together two outstanding and complementary groups located within easy travel distance, allowing excellent synergistic coupling of infrastructure, personnel and resources on a daily basis. Our project will lead to major breakthroughs in the understanding of the key role that microorganisms play in modulating Earth’s biogeochemistry with far-reaching implications for a wide range of research fields.
