Dr. Tim Sweere is a Lecturer at the Department of Earth and Planetary Sciences at ETH Zurich, specializing in geochemical and isotopic processes in marine environments. His research focuses on understanding trace metal cycling, particularly nickel and its isotopes, in modern and ancient oceans. He investigates the interplay between biogeochemical cycles, redox conditions, and their implications for climate and paleoenvironments.
His work spans Cretaceous ocean anoxic events, modern anoxic fjords, and upwelling margins, employing sediment core analyses and isotopic proxies. Key research areas include micronutrient availability (nickel, zinc, molybdenum), redox dynamics, and their role in regulating marine productivity and carbon sequestration. Sweere’s contributions advance methodologies for interpreting geochemical records and linking them to broader environmental changes.
Labs and affiliations include the Institute of Geochemistry and Petrology (ETH Zurich), where he collaborates on projects involving novel X-ray fluorescence core scanning techniques and interdisciplinary paleoenvironmental reconstructions. His research bridges geochemistry, sedimentology, and paleoceanography, addressing critical questions in Earth system evolution.
