PhD position in biogeochemistry/ isotope geochemistry including radiocarbon
The Institute of Geology and Mineralogy at the University of Cologne, Germany, invites applications for a 3-year PhD project in carbon dynamics in arctic permafrost. The position will be based in the Organic Geochemistry & Radiocarbon group, which is part of the interdisciplinary cosmogenic nuclide-dating center CologneAMS.
Global warming is most pronounced in the Arctic, which will have significant effects on the large carbon stocks stored in permafrost soils and sediments the circumpolar region. As a consequence of permafrost thaw, this large carbon pool is exposed to degradation processes resulting in the release of greenhouse gases to the atmosphere. Fluxes and sources of CO2 and CH4 from thawing permafrost depend strongly on the composition and degradability of the organic material as well as various environmental factors. The PhD project aims at determining sources of CO2 and CH4 released from thawing permafrost using carbon isotopic analyses both in the field as well as in laboratory experiments. The project involves technical developments/improvements of analytical devices to measure 14C contents of CO2 and CH4. In addition, organic geochemical methods will be used to determine organic sources and stage of degradation as well as microbial consortia.
The position is limited to 3 years and will start in April/May 2020. The salary will be according to German Public Service Sector salary group TV-L 13, 65%. For further information please contact Prof. Dr. Janet Rethemeyer. As Ph.D. student you will be member of the graduate school of geosciences or another graduate school. The University of Cologne is committed to equal opportunities and diversity.
Application: Please send your application as a single pdf document (including motivation, CV, certificates, names of 1-2 referees) by email to Prof. Dr. Janet Rethemeyer until 20. Feb. 2020.
