Scientist (m/f/d) in Paleo-Oceanography in the frame of the ERC Synergy-Grant "T-SECTOR"
GEOMAR
Posted on May 28, 2025
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 “Paleo-Oceanography“ of research division 1 “Ocean Circulation and Climate Dynamics” is offering the position of a
Scientist (m/f/d) in Paleo-Oceanography
in the frame of the ERC Synergy-Grant "T-SECTOR"
Available from October 1st 2025.
Project Description
For the understanding of the Earth system a quantification of climate-solid Earth feedbacks is required. The global glacial/interglacial climatic changes of the past 1,5 million years led to the periodic waxing and waning of continental ice sheets and caused a vast mass transfer between the continents (ice load) and the oceans resulting in sea level changes of up to 140 m. Mid ocean ridges where 80% of Earth’s volcanism occurs, are sensitive to such pressure changes, but their response to glacial cycles is largely unknown. Models of MOR response to sea level fluctuations predict changes in crustal thickness, chemistry of lavas and hydrothermal activity but comprehensive time series of these MOR parameters have so far not been accessible.
Recent studies have shown, however, that MOR eruptions deposit samples of lava as glass particles on nearby sediments. These carbonate-rich sediments provide an archive of ridge eruptions (glasses) and hydrothermal activity (trace metals) that can be sampled by gravity coring. Through closely spaced new cores, high-resolution time series of volcanism and hydrothermal activity can be achieved and directly linked to the climate record. We plan to obtain such records from slow, intermediate and fast spreading ridge segments over the past 1.5 Ma.
Job Description
The successful candidate will be part of the international team of researchers of the ERC Synergy Grant „T-SECTOR“. She:He will lead the recovery of sediment cores during planned seagoing expeditions and their correlation and chronostratigraphic evaluation. She:He will be responsible for the interpretation of data obtained from application of various core logging methods as well as the production of high-resolution oxygen isotope stratigraphies of selected reference cores. In addition, she:he will play a key role in the planning of and preparations for the expeditions. Further tasks include the scientific interpretation of the data, their presentation at national and international conferences as well as their publication in peer-reviewed scientific journals together with other members of the T-SECTOR team. The successful candidate will regularly communicate with the other team members and will contribute to the management of the project.
Qualification
required:
- a PhD in geology or closely related field
- an internationally competitive research profile in paleo-oceanography based on expertise in one or more specific subject areas proven through publications in peer reviewed scientific journals
- experience in the determination of oxygen and carbon isotope compositions of biogenic carbonates using IRMS and their stratigraphic application
- experience in marine sediment stratigraphy and the establishment of age models
- willingness and ability to participate in sea-going expeditions
- excellent English language skills
desirable:
- practical experience in using geological devices for sediment coring and sea floor sampling
- International academic networking
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 (temporarily possible in consultation with the supervisor) 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 is available for a funding period until June 30th 2029.
The salary depends on qualification and can be up to the class 13 TVöD-Bund of the German tariff for public employees. This is a full-time position. The position cannot be split. Flexible work time models are possible.
