Research
Understanding global change and its societal impacts also requires advancing and applying process oriented research in sedimentology in an interdisciplinary approach. For more than 20 years I study the hydrodynamic behavior of fine organo-mineral aggregates: mud. Mud is the dominant surface cover in the ocean and is very complex as a substance. It comprises many small inorganic particles that freely bind with organic matter. I use field studies to explore small-scale, basic processes of erosion, deposition and transport, use remote sensing to investigate larger scale patterns of sediment distribution, and models to predict the fate of mud in the ocean. I quantified organo-mineral aggregates at continental margins and investigated their transport behavior and scavenging rate [1, 2, 3], their capability to transfer organic carbon and pollutants into ecosystems [4, 6, 7]. I investigated their importance to prevent an efflux of dissolved substances [5]. I collaborated with modelers to improve particle transport models using real data from field studies [6, 8, 9] and joined an international team of experts to develop monitoring and a conservation strategy for policy makers [10]. I am convinced that novel monitoring technologies will drastically increase our understanding of particle transport processes in the Anthropocene [5, 7]. These studies can only be successfully accomplished with interdisciplinary research. Therefore I joined or coordinated research groups from different disciplines of ocean sciences.
