Kennziffer: A31/21
Bewerbungsfrist: 19.03.2021
Öffentliche Ausschreibung

The MARUM - Center for Marine Environmental Sciences at the University of Bremen is offering (under the condition of the grant by the funding party and of job release)

one PhD position (f/m/d) in paleoceanography for 3 years
German federal salary group 13 TV-L (66,66 %)

The earliest starting date is 1 July 2021.

The employment is fixed-term and governed by the Act of Academic Fixed-Term Contract, §2 (1) Wissenschaftszeitvertragsgesetz – WissZeitVG. Therefore, candidates may only be considered for appointment if they still have the respective qualification periods available in accordance with § 2 (1) WissZeitVG.



The Cluster of Excellence “The Ocean Floor – Earth’s Uncharted Interface” is part of the Research Faculty MARUM at the University of Bremen. Within the project Ocean Floor as RECORDER, we are searching for a PhD student (f/m/d) in the area of paleoceanography/climatology to conduct research related to the topic of “Pertubations in high CO2 worlds”.

The project aims to enhance our understanding of paleoclimatic and paleoceanographic conditions during high-CO2 worlds during selected time intervals in the Cenozoic. The research will contribute to the understanding of sensitivities and tipping points through studies of past perturbations and their effects. The project will investigate time and timescale-dependent forcings and feedbacks between, for example, temperatures and greenhouse gas concentrations, while the climate system undergoes pronounced carbon cycle feedbacks. Tasks will include sample processing and measurements for established or new proxies on sediment samples from the International Ocean Discovery Program (IODP) that aid our overall understanding of the response of the Earth System to perturbations and the interaction with relevant feedback processes, potentially collecting new material at sea.


  • Completed MSc or equivalent qualification in the fields of Geosciences
  • Experience in marine science and an interest in geochemical laboratory methods
  • Experience in the interpretation of stable isotope geochemistry and/or elemental geochemistry results
  • Experience in stratigraphic techniques and the construction of age-depth models
  • The applicant should be highly proficient in English, have excellent skills in scientific writing and joy in working in an international and interdisciplinary team
