Research Interests

In many regions, especially in northern latitudes, an increasing level of dissolved organic carbon (DOC) has been observed in terrestrial aquatic ecosystems for several decades. The so-called Browning process has impact on many different areas, i.e. on the water treatment for drinking water production, the fish communities and the penetration depth of light in water bodies.

During my master thesis, I investigated the importance of redox processes during the carbon mobilization. Various studies have found that a large amount of this additional DOC is mobilized in wetlands and the riparian zones. Since the terrestrial and marine systems are connected via streams, which serve as assembly lines for the DOC, the browning will also affect coastal marine ecosystems. The effect of enhanced quantity and changed quality of DOC on coastal ecosystems for instance regarding methanogenesis, microbial communities and primary production is not yet fully understood.

Contributing to this topic, my PhD project will focus on shelf ecosystems and sandy sediments. In my project, I will use an integrated approach combining the eddy covariance technique with biogeochemical assays to link net ecosystem fluxes to the underlying microscale metabolic processes.
