Postdoc position (f_m_x) in micrometeorology

Reference Number 10173

We are seeking a highly motivated Postdoctoral candidate for the newly established Collaborative Research Centre “WETSCAPES2.0” funded by the German Research Foundation (DFG). WETSCAPES2.0 combines the expertise from the University of Greifswald, the University of Rostock, the IGB Berlin, the GFZ Potsdam, the Ludwig-Maximilians-University München, the MPI for Biogeochemistry Jena and the Humboldt-University Berlin. WETSCAPES2.0 focuses on the functional understanding of rewetted fens, including coastal peatlands, in Mecklenburg-Vorpommern (northeastern Germany). The rewetting of previously drained and often agriculturally used fens is leading to the development of novel ecosystems that differ from natural peatlands and are largely unexplored. The monitoring, experimental and modelling research in our new Centre will focus on biogeochemical, hydrological and biological processes, with emphasize on water and matter fluxes within and beyond the peat body and their associated microbiological and biological drivers. In addition to site-level studies, the role of rewetted fens in the broader landscape will be investigated.
