PhD Position (m/f/d) Modeling particulate organic matter dynamics in the North Sea
The Institute of Coastal Systems – Analysis and Modeling hosts a number of highly motivated and experienced researchers in the broad field of coastal research. Our research focus lies on numerical modeling of coastal processes with specific expertise in modeling of atmospheric and marine biogeochemistry and interactions between different environmental compartments on regional and coastal scales. We develop numerical models with the aim to determine the past and current state of the environment and to identify the major drivers for future changes in the system.
The working group for Sediment Transport and Morphodynamics invites applications for a PhD position in the frame of the project APOC focussing on the organic carbon cycle in the North Sea Ecosystem. APOC is a collaborative project with an interdisciplinary team of researchers from several German Marine Research Institutes, which combines Observations and Modelling activities to understand changes in the marine carbon cycle under increasing anthropogenic pressures.
The aim of the PhD project is to apply a coupled hydrodynamics-morphodynamics-biogeochemistry model to investigate the path of particulate organic carbon (POC) from source to sink including flocculation and deflocculation between biogenic and lithogenic particles, deposition and resuspension, and POC degradation during transport and sedimentation. In particular, anthropogenic impacts such as resuspension by bottom trawling, altered fluvial POC inputs by damming, channel dredging, sand mining and dumping need be addressed by numerical modeling. The position is limited to 36 months.

- model application to investigate seasonal and annual variability of POC cycling and sequestration in the North Sea sediments
- conducting sensitivity experiments and hindcast simulations to quantify the effectiveness of individual management measures
- analysis and assessment of model results with respect to POC fluxes between the sediment-water interface and carbon sequestration
- implementation and analysis of relevant climate projection scenarios
- working as an integrative part of a motivated multidisciplinary team within the institute and external academic partners
- writing scientific publications in peer reviewed journals
- presentation of results at meetings and international conferences
- Master in physical oceanography, geosciences, environmental sciences or related disciplines
- knowledge on sediment dynamics and marine ecosystem
- interest in coastal shelf modeling
- experience in scientific programming with FORTRAN and related analysing programming languages (e.g. MATLAB, R, Python) would be an advantage
