ongoing projects

  • Peatland Climate Protection on the Baltic Sea Coast – ANK-funded collaborative project with the IOW and the Baltic Sea Foundation (2024–2034). The project accompanies the rewetting of coastal peatlands in Mecklenburg‑Western Pomerania and investigates their climate impact and underlying biogeochemical interactions. Eddy covariance measurements are used to quantify greenhouse gas fluxes.

Previous Projects

  • Gas bubbles in freshwater ecosystems: origin, fate, and bubble-mediated transport – DFG-funded project in cooperation with Rheinland‑Palatinate Technical University Kaiserslautern‑Landau (2019–2024). The study investigated the formation, composition, and relevance of gas bubbles in aquatic environments, focusing on the biogeochemical and physical processes that control the release of greenhouse gas from freshwater systems.
