Marine Geosystems

The seabed represents a dynamic boundary layer between the oceans and the deeper geological formations in the subsurface. Biogeochemical element cycles in the ocean, the composition of bottom water and the formation of resources in the seabed are significantly regulated by the exchange of substances across this boundary layer. The Marine Geosystems research unit investigates this exchange of substances, which is controlled by microbiological, chemical and physical processes. To analyse and monitor these processes, we are developing sea-going sensor and sampling platforms on which we apply robotic and artificial intelligence methods. The samples collected worldwide are analysed in our laboratories for environmental analysis, (radio)isotope analysis and microbiology using state-of-the-art methods. The data sets obtained are coupled with machine learning methods and interpreted using numerical modelling.

We want to reconstruct the exchange processes on the sea floor on geological time scales, document their current state and make predictions for the future. This will provide a scientific basis for the sustainable use of seabed resources and an approach for minimising the impact on the oceans and ecosystems.
