Biogeochemical processes

We investigate and quantify post-depositional biogeochemical processes in the seabed with particular emphasis on pathways that couple the cycles of carbon, sulfur, iron and manganese. Our major research objectives are 2) to better understand and comprehensively determine how changes in depositional, environmental and oceanographic conditions over time affect these biogeochemical processes, and 2) to investigate and quantify biogeochemical processes and thus diagenetic overprint in deeper subsurface sediments. The aim of these studies is to improve the quality and validity of paleoenvironmental reconstructions from sedimentary archives and to decipher and study novel biogeochemical processes and their role in the global carbon cycle.
