Job description:

PhD Position “DynaDeep – Biogeochemical processes in the Dynamic Deep subsurface of High-Energy Beaches” (m/f/d)

Background
The DFG-research unit DynaDeep aims for a deeper understanding of the physical and biogeochemical processes in the subsurface of high-energy beaches, the so-called subterranean estuary.
The specific goal of the PhD project is to understand how oxic and anoxic microbial processes in the porous sand body of a beach are controlled by the fluctuating matter inflow caused by waves, tides, and fresh groundwater discharge and how this shapes the overall carbon and nutrient cycling in the subterranean estuary.

In detail, we seek to combine in-situ measurements and laboratory experiments in order to quantify the flux of oxygen and other electron acceptors and the spatial heterogeneity of their consumption in beach sediments as a function of the overlying hydro- and morphodynamics. The work involves close cooperation with another 7 PhD projects. For further information please visit uol.de/icbm/verbundprojekte/dynadeep

Tasks
You will be responsible for the

• •  conduct of field measurements and setup incubation experiments using flow through reactors
  •  performance of laboratory‐scale analysis of flow dispersion and heterogeneous reaction rates
  •  measurement of reaction rates in sediments under transient conditions
  •  application and development of empirical transport-reaction models
  •  presentation of results in scientific journals and to non-experts in comprehensible form

Requirements

• • A qualifying academic university degree (M.Sc. or diploma) in environmental sciences, marine biogeochemistry or comparable disciplines.
  •  a background in the measurement and analysis of biogeochemical transport and reaction rates, preferably with knowledge of diffusion/flow dispersion and oxygen dynamics.
  • very good English language skills (written and spoken).
  • the willingness to carry out field work, also under harsh conditions, and
  • a strong interest in collaborative research.
