Fachbereich Geowissenschaften - Institut für Geologische Wissenschaften Tektonik und Sedimentäre SystemeDoctoral student in marine sedimentology and paleo-weathering history (m/f/d) with 75%-part-time-job limited to 3 years Entgeltgruppe 13 TV-L FU reference code: PALAVAS 2023_engl Bewerbungsende: 15.06.2023

We invite applications for a Doctoral Candidate in the research group "Sedimentary Systems" of the Institute of Geological Sciences at the FU Berlin.
The research project within the German-French bilateral project "PALAVAS – Present and Past Weathering Fluxes from Tropical Volcanic Islands" in which the interaction between weathering and erosion in tropical volcanic islands will be evaluated. Within this framework, two doctoral projects on the German side (at GFZ Potsdam and FU Berlin, respectively) and two positions on the French side (IPGP Paris and EDYTEM Chambéry, respectively) will collectively test the hypothesis that the degree and rates of weathering and erosion depend on age of the underlying bedrock. Back through time, however, centennial to millennial-scale variations in climate may modify weathering and erosion rates, and these trends may be preserved in offshore sediment archives. We will use classical elemental geochemistry and state-of-the-art novel Beryllium and Lithium isotopes as tracers of modern and past weathering and erosion rates, in conjunction with biomarker analysis and numerical modelling.

Within PALAVAS the here advertised doctoral project will focus on quantifying changes in weathering and erosion of volcanic islands from marine sediment core and geophysical data over Quaternary timescales. The project will be led by Prof. Anne Bernhardt at the Freie Universität Berlin in cooperation with the Ifremer in Brest (France). The second German project focuses on identifying modern weathering and erosion processes by geochemically characterizing soils and modern river sediments and will be led by Dr. Hella Wittmann-Oelze at GFZ Potsdam and will be advertised separately. The French projects will be led by Dr. Julien Bouchez (IPGP Paris) and Dr. Fabien Arnaud (EDYTEM Chambéry) and will be advertised separately. All successful applicants will be working closely together and will carry out research visits among the different research facilities.

What we offer:
•           Ambitious and varied tasks in a dynamic and international research environment
•           Public service benefits
•           Extensive training opportunities
•           Flexible working hours and conditions
•           Working in the vibrant city of Berlin
•           A family-friendly work environment
•           Training opportunities and career development at Dahlem Research School

We are looking forward to your application!

Equal opportunity is an inherent part of our personnel policy. Therefore, we are particularly welcoming applications from qualified women. Severely disabled persons will be given preferential treatment in the case of equal qualification.
