Marine Isotope Geochemistry

The research of the research group for Marine Isotope Geochemistry  is focused on the understanding of past and present processes and changes in the ocean and the climate system. In particular, we are interested in trace elements and their isotopes in the ocean and their role as tracers of present and past element input and fluxes, geochemical processes, internal cycling, and as tracers of past ocean circulation changes. Our current projects include the use of rare earth element (REE) concentrations and isotope ratios of Nd, Sr, Pb, Si, and Fe in seawater, suspended particles, porewaters, and marine sediments, including biogenic archives of past ocean conditions and lithogenic material deposited on the seafloor.
