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 research unit Marine Geosystems of the research division Marine Biogeochemistry is offering a Postdoc position in geochemical modeling (m/f/d) focusing on offshore freshened groundwater discharge starting not later than March 1, 2024.
Job Description
Research work will be performed in the DFG-funded project "Offshore freshened groundwater systems—Emergence and persistence analysis by geochemical modeling (OFFING)." Our current knowledge of the functioning of OFG systems is still very limited, which is due to a lack of available data that would allow for an unambiguous interpretation of OFG emplacement. In many cases it remains elusive whether OFG bodies are at present actively recharged/discharging or if the systems are rather equilibrating after a drastic change of hydrological conditions due to deglaciation and sea-level rise. To improve the current state-of-the-art, we intend to use the wealth of geochemical data from two well-studied working areas (New Jersey Shelf, USA and Canterbury Bight, NZ) with the main goal of constraining the timing and emplacement mechanisms of two OFG systems by carrying out thorough quantitative evaluations of high-resolution pore water geochemical data from IODP Legs 313 and 317 and by using 1D and 2D numerical transport-reaction models.
Tasks
- Evaluation and interpretation of geochemical, geological, and geophysical data from IODP Legs 313 and 317
- Application and adaptation of 1D and 2D numerical modeling schemes in well-defined case studies
- Publication of relevant results in scientific journals
Qualification
- Ph.D. (or equivalent) in Geosciences or related disciplines
- Fluency in spoken and written English
- Solid background in marine porewater geochemistry and/or hydrogeology
- Proficiency in the interpretation of complex data sets and publication of scientific data proven by appropriate publication record
Advantageous skills
- Specific knowledge of sediment/porewater interactions in coastal marine systems
- Experience in the application and development of numerical reactive-transport models
- Experience in object-oriented programming
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 and New Year's Eve
- Company pension plan and capital-forming benefits
The position is available for a funding period of 2 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 full-time position and can be split. Flexible working hours are possible. The fixed-term contract shall comply with Section 2 Paragraph 1 of The Act of Academic Fixed-Term Contract (German WissZeitVG).
Closing date: December 11, 2023
