Posted on Thursday, November 2, 2023

GEOMAR Helmholtz Centre for Ocean Research Kiel is a foundation under public law jointly financed by the Federal Republic of Germany (90%) and the State of Schleswig-Holstein (10%). It is one of the internationally leading institutions in the field of marine research.

Through our research and our commitment to the transfer of knowledge and technology, we contribute significantly to the preservation of the function and protection of the ocean for future generations.

The Horizon Europe project OceanICU aims at improving our understanding of the ocean carbon cycle and reducing the uncertainties of how anthropogenic activities, such as deep-sea mining, affect its functioning. Scientific results will contribute to international regulations for seabed mineral exploitation. Within this project the research unit Marine Geosystems of the research division Marine Biogeochemistry is offering a

Researcher position(m/f/d) in numerical modelling of biogeochemical impacts of deep-sea mining

starting as soon as possible.

Job Description

You will perform numerical simulations on the dispersal and redeposition of suspended sediment plumes generated in the course of mining of polymetallic nodules. Model scenarios of industrial-scale operations will be guided by multi-disciplinary data from a mining trial executed in a relevant deep-sea environment. You will work with and modify numerical codes for modelling of ocean hydrodynamics and biogeochemical processes. You will analyse the model results and assess the impacts of future deep-sea mining activities on the carbon cycle. You will publish your results in the international peer-reviewed literature and present them at international conferences and workshops.



  • Diploma / Master in the field of natural sciences (geosciences, oceanography, marine sciences or similar)
  • Proven programming skills (e.g., Matlab, C/C++)
  • Experience in working with numerical modelling code (e.g., oceanographic and/or biogeochemical models)
  • High level of proficiency in English


  • Experience in interpreting and working with oceanographic and/or biogeochemical data
  • Knowledge in hydrodynamics or fluid dynamics
  • Knowledge in numerical mathematics
  • Ability and willingness to closely collaborate in an interdisciplinary team
  • Good communication skills
  • Ability to work target-oriented


At a workplace, directly on the Kiel Fjord with many leisure and recreational opportunities, we offer you:

  • Good conditions for work-life balance: We offer, among other things, the possibility of mobile working and individual working time arrangements, vacation courses for the children of our employees, and good support in finding a place in a daycare center at the Kiel site
  • Support services for professional and personal life situations
  • An exciting work environment with the opportunity to provide important impetus for the development of sustainable solutions
  • Exciting topics in an international environment
  • Work in the field of marine and climate research, a forward-looking area with social significance
  • 30 vacation days + additional time off at Christmas Eve and New Year's Eve
  • Company pension plan and capital-forming benefits

The position offers the possibility to attain a doctoral degree in natural sciences. The position is available for a period of 36 months. The salary is up to the class E13 TVöD-Bund of the German tariff for public employees. This is a full-time position. The position can be split. The fixed-term contract shall comply with Section 2 Paragraph 1 of The Act of Academic Fixed-Term Contract (German WissZeitVG).
