Radiogenic isotope signatures of a sediment cores and suspended particulate matter of large scale river systems – provenance and paleoclimate studies.

One focus is on the impact of environmental changes on the Rio de la Plata and Amazon River dynamics and the sediment and elemental supply to the ocean over time. We perfom detailed multi-proxy isotope investigations of the Rio de la Plata and Amazon riverine discharge to gain insight into changing river dynamics and chemical weathering due to changes in climate, vegetation and land use, and to characterize the elemental influx and isotope composition to the ocean.
