The Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) is a member of the Helmholtz Association (HGF) and funded by federal and state government. AWI focuses on polar and marine research in a variety of disciplines such as biology, oceanography, geology, geochemistry and geophysics, thus allowing multidisciplinary approaches to scientific goals.

PostDoc "Biogeochemical interactions and exchange processes between seafloor habitats and the water column in the Wadden Sea" (m/f/d)


Embedded within the framework of the Coastal Ecology section, we seek a communicative and ambitious postdoctoral researcher (f/m/d) with expertise in biogeochemistry of marine and tidal environments with a specific interest in bentho-pelagic coupling, carbon cycling and nutrient fluxes in the Wadden Sea under the influence of a changing environment.


  • The core task of the position is to investigate biogeochemical processes and interactions at the interface between seafloor sediments and the water column in inter- and subtidal habitats of the Sylt-Rømø Bight (e.g. microphytobenthic communities of sandy environments, biogenic reefs (bivalves), seagrass beds).
  • A special focus will be on the quantitative description of bentho-pelagic coupling by the implementation of in-situ measurements and/or experiments, such as sediment incubations, eddy correlation, surface properties, or lander deployments, to describe exchange processes and their relation to the ecology and habitat properties of the Wadden Sea.
  • This will involve the integration of field measurements with data from long-term observations and highly-resolved FERRYBOX data, to facilitate a spatio-temporal perspective on exchange processes along environmental gradients (e.g. bathymetry, habitat properties, hydrography, biological productivity).
  • The study of bentho-pelagic exchange processes will facilitate a more complete understanding of the Wadden Sea ecosystem and it is a strategic task to hone the collaborative potential with existing research foci of our section (e.g. benthic ecology, food webs, coastal geology).


  • PhD degree with focus on biogeochemistry, marine ecology or similar.
  • Additional experience with techniques assessing bentho-pelagic fluxes, both automated and hand measured nutrient techniques and HPLC systems for accompanying pigment analyses is of advantage.
  • Research independence and experience with interdisciplinary research will be highly ranked.

The Coastal Ecology section features a diversity of research disciplines (from molecular biology to coastal ecology) and you are expected to be open to collaborations within the expertise of our section.
