[Job] Opportunity at the Institute for Chemistry and Biology of the Marine Environment (ICBM), University of Oldenburg
The Institute for Chemistry and Biology of the Marine Environment (ICBM) at the University of Oldenburg, Germany, invites applications for the position of a Doctoral Candidate (m/f/d).
Join a dynamic research environment at the Institute for Chemistry and Biology of the Marine Environment (ICBM). We invite applications for a Doctoral Candidate (m/f/d) position, focusing on stable silicon isotopes in diatoms for climate reconstruction. The project contributes to a broader investigation of climate variability in the Pacific Southern Ocean over the last 8 million years.
About ICBM: ICBM is renowned internationally for its collaborative approach, fostering cooperation among more than 20 research groups spanning chemistry, biology, physics, and mathematical modeling. The institute seeks to unravel the mysteries of marine environmental systems through a multidisciplinary lens.
Research Focus: Within the Marine Isotope Geochemistry working group, this doctoral position delves into the application of stable and radiogenic isotope systems (Si, Fe, Nd, Sr, Pb) and trace element concentrations. The project is part of a larger collaborative initiative investigating climate variability in the Pacific Southern Ocean over the last 8 million years, utilizing IODP Expedition 383 (DYNAPACC) sample material.
Project Overview: The successful candidate will play a pivotal role in exploring stable silicon (Si) isotopes in diatoms to reconstruct past changes in surface water nutrient supply and utilization. Specifically, the project spans the Pliocene-Pleistocene and Mid-Pleistocene Transitions, using marine sediment cores collected during IODP Expedition 383.
Your Role As the appointed doctoral candidate, you will be responsible for the processing and analysis of samples for stable Si isotopes. Your duties extend to documenting, interpreting, and publishing data and results, fostering collaboration with other project partners.
Qualifications: Candidates should possess a qualifying university degree (M.Sc. or diploma) in earth sciences, analytical chemistry, or a related field. A strong background in inorganic-geochemical sample processing and analysis, preferably in mass spectrometric analysis of trace elements and metal isotopes, is advantageous. A foundation in paleoclimate/paleoceanography and/or geochemistry is required, with a background in diatom taxonomy considered a plus. Excellent English language skills (written and spoken) are essential.
Salary: Competitive salary in accordance with TV-L E13 (75%) collective agreement.
Application Process: If you are ready to take on this exciting challenge, please submit your application, including a cover letter, curriculum vitae, certificates, and contact information for up to three references. Applications should be compiled into a single document and preferably sent by email to with the subject "IODP 383 Silicon Isotopes" by the deadline of February 29th, 2024.
Diversity and Inclusion: The University of Oldenburg is committed to increasing the representation of female employees in the scientific field. Female candidates are strongly encouraged to apply, and in accordance with § 21 Section 3 NHG, they will be preferentially considered if equally qualified. Additionally, applicants with disabilities will be given preference in cases of equal qualification. For further inquiries about this position, please contact Dr. Claudia Ehlert at
