The Helmholtz Centre Potsdam - GFZ German Research Centre for Geosciences is the national centre for geosphere research. As a member of the Helmholtz Association
we are part of the largest German scientific organization. With around 1,300
employees we develop a sound understanding of the systems and processes of the solid Earth as well as strategies and options for action to face global change and its regional impacts, to understand natural hazards and reduce associated risks, and to assess the influence of humans on the Earth's system.
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.
