The Helmholtz Centre Potsdam - GFZ German Research Centre for Geosciences is the national centre for geosphere research. As a member of the Helmholtz Association of German Research Centres
we are part of the largest scientific organization in Germany. With approximately 1,300
employees our key mission is to secure a profound understanding of the systems and processes of solid Earth, to develop strategies and options for action in addressing global change and its impacts on a regional level, to understand natural hazards and to minimize associated risks, to ensure the sustainable provision of energy and raw materials for a high-tech society and to evaluate the influence of human activity on system Earth.
As a partner in Geo.X
, the GFZ has access to an excellent network of other geoscience institutions in Potsdam and Berlin. This largest regional concentration of geoscientific competence in Europe offers first-class cooperation and development opportunities.
For section 3.3 Earth Surface Geochemitry (department "Geochemistry"), we are looking for a:
The PhD position is part of a DFG-funded project (PI Dr. Michael Henehan) investigating whether the strength of the silicate weathering feedback – which moderates Earth’s climate and atmospheric CO2 on geological timescales – can vary, and whether temporary weakening of this feedback can cause transient global warming events. More specifically, it will focus on the climate and carbon cycle of the middle-late Eocene, around the enigmatic Middle Eocene Climatic Optimum (~40 Ma). The chosen PhD candidate will look at global silicate weathering fluxes at this time using a combination of Li and Si isotopes in marine microfossils (foraminifera and radiolarians) and global carbon cycle models. The successful applicant will work within a vibrant, diverse, international and multidisciplinary research group (Section 3.3, Earth Surface Geochemistry) at the GFZ. They will receive training in carbon-cycle modelling, microfossil taxonomy, and in the methods of silicon and lithium isotope analysis within the Helmholtz Laboratory for the Geochemistry of the Earth Surface, a world-class facility equipped with metal-free clean laboratories and multi-collector and single-collector ICPMS instruments. Funds are also set aside for attendance at the Urbino Summer School in Paleoclimatology in Italy.
