The Helmholtz Centre Potsdam – GFZ German Research Centre for Geosciences is the national research centre for Earth sciences in Germany. With approx. 1260 employees, the GFZ is conducting interdisciplinary research on the “System Earth” and the influence of humans on the planet. As a member of the Helmholtz Association, it is part of Germany’s largest science organization. For Section 3.3 “Earth Surface Geochemistry” and in collaboration with Section 5.1 “Geomorphology" we invite applications for a
Job Vacancy No. 1603Research takes place within the DFG priority project "Earthshape – Earth surface shaping by biota" (Earthshape.net) in which the interaction between biological, geochemical, and geomorphological processes in landscape evolution is explored along a climate gradient in Central Chile. Within this framework, two doctoral projects will use modern river sediment and marine paleo-sediment cores to investigate how Holocene hydrological changes influenced vegetation, weathering, erosion, and sediment transport (EarthShape Project 5 SECCO - “The coupled vegetation, weathering, erosion, and sediment-export response to climate change unraveled from novel proxies in Chilean marine sediment“).Within SECCO this doctoral project (mSECCO) will focus on identifying modern processes by geochemically characterizing soils and modern river sediments and will be led by Dr. Hella Wittmann-Oelze (Section 3.3) and Dr. Dirk Sachse (Section 5.1). The project will be based in GFZ´s section 3.3, whereas the second project focusing on changes over Holocene timescales (pSECCO) will be led by Prof. Anne Bernhardt at the Freie Universität Berlin and will be advertised separately. Both doctoral students will be working closely together.
- field work in the Chilean Coastal and Andean mountains for sampling river sediment and river water,
- close collaboration within an interdisciplinary German-Chilean network of both leading scientists and other doctoral students in Geosciences, Ecology, Soil Sciences,
- dynamic and interdisciplinary supervisor team (2 female and 2 male scientists) with backgrounds in inorganic and organic geochemistry, sedimentology and paleoclimatology,
- reconstruction of changes in paleohydrology, vegetation and earth surface processes through a diverse geochemical characterization of samples: Biomarker isotopes (δD & δ13C), Lithium stable isotopes, and cosmogenic nuclides (meteoric 10Be/9Be ratios)
The unique combination of these proxies allows the measurement of erosion- and weathering rates as well as the quantification of vegetation and hydrological changes along the Chilean climate gradient and is aimed at addressing the question: Is vegetation change the main driver of landscape change in Chile since the last deglacial climate change?
- university degree (master / diploma) in Geosciences
- good (English) communication skills; willingness for interdisciplinary exchange with colleagues in the priority program
- experience in geological field work; knowledge of Spanish is of advantage
- MSc thesis including either geochemical, sedimentological, and if possible also isotope work
- ability to work independently in geochemical laboratories with acid digestions and or/ organic solvents
