GEOMAR Helmholtz Centre for Ocean Research Kiel is a foundation of public law jointly financed by the Federal Republic of Germany (90 %) and the state of Schleswig-Holstein (10 %) and is one of the internationally leading institutions in the field of marine sciences. Currently GEOMAR disposes over an annual budget of approx. 80 million Euro and has approx. 1000 employees.
The research unit Biogeochemical Modeling of the research division 2: Marine Biogeochemistry is offering a Postdoc in biogeochemical ocean modelling: integration of new biogeochemical process parameterisations into ocean models, starting on April 1st, 2023 or later.
Project Description
The EU Project OceanICU addresses the role of the Biological Carbon Pump (BCP) for carbon storage in the ocean under a changing climate. Recent work suggests a much higher level of complexity in BCP functioning than previously thought, among them the effects of higher trophic levels, temperature, pH and size structure. To investigate this further, parameterisations of the different biogeochemical and biological processes developed from already existing and new observations will be incorporated into biogeochemical models and evaluated for their effect on the BCP and its potential future change. Selected parameterisations will be implemented into Earth system models, and the results will feed into tools that can predict the state of the C cycle under combined climate and human impact scenarios.
Job Description
The scientist is expected to use, improve and analyse global biogeochemical ocean models, as part of an interdisciplinary team. Initial work will involve the integration of new biogeochemical and biological process parameterisations into state-of-the art global biogeochemistry-circulation models (TMM, UVic ESCM) in close collaboration with other modelers and observing scientists. Focus should be on appropriate process parameterisations (via assessment of model results against observations), as well as on numerical efficiency for later implementation in large-scale Earth system models (for example, FOCI). A further aspect of the work includes the assessment of the processes’ impact on the BCP. This involves definition and setup of assessment metrics in collaboration with other project partners. The candidate is further expected to support the transfer model results to other project partners.
Qualification
We are looking for a creative and committed scientist with a PhD in a natural sciences subject and extensive knowledge of global or regional ocean biogeochemical models.
Required:
- A PhD in natural sciences
- Experience with modifying, running and analysing global or regional biogeochemical ocean models
- Knowledge of ocean biogeochemical cycles and their role in the Earth system
- Willingness to work with international partners and in an interdisciplinary team
- Good English language skills (oral and written)
Desired:
- Experience with at least one of the global biogeochemical ocean models TMM, FOCI (or NEMO), UVic ESCM
- Experience in biogeochemical model assessment against observations
- Experience with metric development
- Good programming skills (Fortran, MPI)
The position is available for a funding period of four years. The salary depends on qualification and could be up to the class 13 TVöD-Bund of the German tariff for public employees. This is a full-time position. The position can be split.
