PhD fellow in Department of Geosciences and Natural Resource Management

The Department of Geosciences and Natural Resource Management, Faculty of Science at University of Copenhagen is offering a PhD scholarship on the investigation of the interlink between marine productivity and seawater redox, with implications for past fluctuations in Earth’s atmospheric oxygenation. We intend the use of suitable non-traditional and radiogenic isotope tracers to approach the topic.
We envisage a start of the project on April 1, 2019, or as soon as possible thereafter. The project will be based at Department of Geosciences and Natural Resource Management, Faculty of Science at University of Copenhagen, within the research group of Geochemical, Petrological and Mineralogical Earth Processes, and it will conducted in close collaboration with other universities outside of Denmark.  
Description of the scientific environment 
Department of Geosciences and Natural Resource Management (IGN) is a part of Faculty of Science at University of Copenhagen. The research areas in the Geology Section include Earths’ physical structure and history, volcanoes and earthquakes, movement and quality of groundwater, the different ice ages and how landscapes have been shaped through time.  
The research groups work within a wide range of the classical geological disciplines; from sedimentology, basin geology, petrology, mineralogy, and geochemistry to palaeontology, and thus cover topics ranging from the Earth’s ancient history to the present as well as the evolution of life. 
Research is also conducted in water resources, including the availability, movement and quality of groundwater, as well as geologically applied geophysics which is used in mapping and understanding of the subsurface. 
Within the research group “Geochemical, petrological and mineralogical Earth science”, research is focused on using the geochemistry, mineralogy and petrology of rocks to understand the origin and evolution of the Earth’s crust, mantle, atmosphere, biosphere and hydrosphere, how and why these reservoirs have changed, and which geological and tectonic processes have shaped our planet over geological time.] 
Project description 
Non-traditional stable isotopes (Fe, Cu, Zn, Cd, Mo, Cr, U, Fe etc.) have become one of the central new fields in geo(bio-)chemistry and can be used to further advance our understanding of metal cycling within complex low-temperature systems. These isotope systems can address critical questions regarding sources, mobility, and fixation of metals, and in the field of Earth system science these tracers currently experience an unprecedented explosion in their diversity of applications. The use of non-traditional isotope systems has become central in the reconstruction of past marine and continental evolution. This project attempts to further contribute, via development and application based approaches, to proclaim Cr, Cd and U stable isotopes as a powerful triple redox-sensitive element system which can tell us more about the interlink between marine bioproductivity levels and fluctuations in Earth’s atmospheric oxygenation, which we would eventually like to project to important periods in Earth’s history. 
The Ph.D.- project is two-folded: 1) a development part the student will expand into suitable ion chromatographic elution schemes designed to obtain pure separates of redox-sensitive elements from marine biotic and abiotic carbonates and black shales 2) an application part where the student will use non-traditional stable isotopes to investigate Late Neoproterozoic-Early Cambrian sample suites, amongst others, from China and Namibia. 
The PhD scholar will be part of an interdisciplinary and cross-disciplinary research team with a big international network. The project demands willingness and ability to work in geochemical laboratories and also an interest in fieldwork during which some of the sample suites are planned to be collected. In addition, it is expected that the candidate is flexible with respect to shorter visits in other universities during which analytical sessions will be conducted.
