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.

For the implementation of the DFG-funded research project “The hydrogeological regime of the TAG sulfide mound on the Mid-Atlantic Ridge - Insights into metal fluxes from reaction-transport modelling” in the Priority Programme “Dynamics of Ore Metals Enrichment – DOME (SPP 2238)", the research group “seafloor modelling” is seeking a

Doctoral Researcher (m/f/d)
investigating metal transport in submarine hydrothermal systems using numerical methods

starting on October 1st 2023. The position offers the possibility to attain a doctoral degree in natural sciences.

The priority program “Dynamics of Ore Metals Enrichment (DOME)” aims to address fundamental questions regarding element transport and mineralization in complex chemical systems. It integrates empirical field studies, experimental work, and numerical process modeling to understand natural ore forming systems. The successful candidate will be part of a network of PhD students researching different aspect of ore forming systems. The offered position is in the field of submarine massive sulfide accumulations on slow-spreading mid-ocean ridges. The goal is to couple a numerical hydrothermal transport model, hydrothermalFoam, to GEMS, a Gibbs Energy Minimization Software for Geochemical Modeling, and to use the coupled model to constrain fluid rock interactions and associated feedbacks within submarine hydrothermal mounds.

Job Description

You will carry out numerical experiments to investigate feedbacks between hydrothermal flow and dissolution/precipitation reactions in submarine hydrothermal systems. Building on our existing tools, you will design and build a coupled reaction-transport model for submarine sulfide mounds. This work will include research stays at our partners at the New Mexico Bureau of Geology and Mineral Resources (USA) and will be done in close collaboration with our partners within the DOME SPP.


Prerequisites for a successful application are a scientific university education (diploma or master) in the field of natural sciences (geosciences, applied mathematics, physics or alike). Numerical modeling skills in relevant fields along with programming (mainly C++, Python) and English communication skills are required.

Also desirable are

  • background in hydrothermal systems
  • knowledge of openFoam
  • expertise in thermodynamics of fluid-rock interactions
  • experience in seagoing marine research
  • experience in marine geosciences


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

  • An inspiring work place at one of the leading marine institutes
  • Access to state-of-the art computing infrastructure
  • An Open Science and open-source culture
  • Good conditions for work-life balance including 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
  • 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 is available for a funding period of up to three years.

The salary depends on qualification and could be up to the class E13 TVöD-Bund of the German tariff for public employees. This is a part-time position according to 75 % of a full-time equivalent. The position cannot be split. The fixed-term contract shall comply with Section 2 Paragraph 1 of The Act of Academic Fixed-Term Contract (German WissZeitVG).
