PostDoc "APOC - Anthropogenic impacts on particulate organic carbon cycling in the North Sea"

Background
APOC is a collaborative project funded by the BMBF (German Federal Ministry of Education and Research). The overarching goal is to understand how the cycling of particulate organic carbon (POC) contributes to carbon sequestration in the North Sea and how this ecosystem service is compromised by global change and human pressures. In detail, we seek to combine hydroacoustic mapping, turbulence and resuspension measurements with biogeochemical analysis of POC remineralization in order to:



  • quantify the POC transport and transformation processes along lateral POC transport routes as a function of hydro- and morphodynamics,

  • assess the role of anthropogenic factors (bottom trawl) on POC mobilization and transport,

  • parameterize POC transport, remineralization and sedimentation processes, and extrapolate rates in the North Sea.





    • Tasks
    You will



  • plan and conduct ship-based measurements to determine POC distribution and degradation rates in relation to key environmental parameters hydrodynamics, sediment morphodynamics) and human pressure

  • design and conduct artificial large-scale resuspension experiments on the seafloor (bottom trawl)

  • analyze suspended particle and POC composition, including isotope measurements

  • apply and develop empirical transport-reaction models

  • present results in scientific journals and to non-experts in comprehensible form





    • Requirements



  • PhD in geoscience, bioscience or environmental sciences

  • Expertise in organic carbon mineralization processes

  • Expertise in sediment transport and depositional processes in coastal waters

  • Experience in carbon analytics and isotope geochemistry

  • Experience in data based inverse modeling

  • Willingness and capability to participate in seagoing expeditions
