Post Doctoral Position in Isotope Geochemistry and Paleoclimatology
GEOMAR - Helmholtz Centre for Ocean Research
Kiel, Germany
Job Description
The ERC CoG HighBorG focuses on climate-carbon dynamic reconstructions of past warm periods in our Geologic record within the Paleogene and Neogene, in search of tipping elements and climate analogues among different climate states, and further exploration of Earth system response through Earth System modelling. As such, a strongly interdisciplinary and collaborative group will aim at millennial scale reconstructions of seawater pH and atmospheric CO2, seawater temperature and ice sheet dynamics, as well as aspects of the marine carbon cycle. To achieve this, both established methods and new analytical techniques will be developed. The successful candidate will be generating records of seawater pH/atmospheric CO2 with the boron isotope proxy on foraminifera and fossil corals, and will constrain seawater temperature, sea level and marine carbon cycle with a combination of stable isotopes and elemental ratios. The post doc will obtain training on Paleogene and Neogene foraminifera taxonomy, and will be given the opportunity to contribute to the development of new analytical methods for isotope geochemistry. Responsibilities also include clean lab analytical chemistry (inorganic), processing of sediment cores and foraminifera picking with the team’s student support. The post doc will be preparing and analyzing marine carbonates (corals and foraminifera) for isotopes and trace elements using the state of the art analytical laboratories at GEOMAR, organizing and data archiving work, statistical processing, interpreting and publishing in peer reviewed journals, and disseminating results in meetings and conferences. The post doc will have assistance by the team’s PI and technical support and will oversee the student helpers who assist in sediment core processing and foraminifera picking.
Qualification
Essential:
- PhD in Earth Sciences, Chemical/or paleo-oceanography, Geosciences, or similar
- Experience in a clean lab and inorganic chemistry, including work with mass spectrometers
- Knowledge of Paleogene/Neogene climate and key carbon cycle questions
- Expertise in data processing, evaluation of data quality and basic statistics
- Excellent writing and spoken English
- Publication and presentation record as per career level
Desirable:
- Previous experience in foraminifera geochemistry, boron isotopes and trace elements
- Detailed understanding of data reduction strategies in isotope and elemental geochemistry
- Ability to operate Thermo Neptune and Thermo Element largely independently
- Programming with Python, R, Matlab or similar
- Being able to demonstrate creative and critical thinking skills, decision making and problem solving skills, self motivation and curiosity
