In the framework of the European H2020 Marie Skłodowska-Curie Action Innovative Training Network P-TRAP (Preventing Phosphorus Input to Surface Waters – New Concepts in Trapping, Recycling and Management) the Department of Earth Sciences at Utrecht University is looking the for a highly motivated candidate to fill a PhD position to study the
Effects of Fe supplementation on the ecology and P dynamics in eutrophic lakes
P-TRAP tackles two urgent interlinked global problems: Potential shortages of phosphate (P) for producing agricultural fertilizers and the decline of surface water quality upon excess phosphate input. P-TRAP targets the P flux from artificially drained agricultural areas and the internal P load of lakes. By this, P-TRAP aims at intercepting the undesired flux of phosphate from agricultural systems into surface waters and developing a phosphate recycling strategy.
The project of the PhD student (ESR 11) is dedicated to the effects of iron supplementation on the ecology and phosphate dynamics in eutrophic lakes. Eutrophication is still the main cause for many European lakes to have an ecological status of less than ‘good’. The ESR will evaluate iron addition to lakes as a mitigation technique to improve their ecological status. The research will include field sampling campaigns, field and laboratory experiments, biogeochemical analyses, as well as modelling of element cycles in lakes. The project will be performed in close collaboration with Dutch and international partners and involves secondments at academic partners in the consortium but also at companies which are partner organisations in the P-TRAP project.
The main project leader and daily supervisor will be dr. Thilo Behrends at Utrecht University. Dr. Stefan Pfeiffer at University of Bayreuth, Germany, will be co-supervisor.
We seek an enthusiastic PhD student holding an MSc degree (at the start of the contract) that ensures appropriate background knowledge in environmental sciences, earth sciences and/or (environmental) chemistry, and with a strong passion for biogeochemistry. You have a solid knowledge on biogeochemical processes in aquatic and terrestrial environments. Experience in the collection of samples from surface waters and aquatic sediments and their analysis is helpful but not required.
You approach scientific problems with determination and eager to develop multidisciplinary skills. You must be willing to travel abroad for secondments and measurement campaigns, and to present your research to an international research community. As this project requires close collaboration within the consortium, candidates are expected to be excellent team players. You also have excellent written and spoken English skills.
According to EU eligibility criteria, researchers may be of any nationality, BUT must be at their early carrier stage and may not have resided or carried out their main activity (work, studies, etc.) in The Netherlands for more than 12 months in the 3 years immediately prior to the starting date of the fellowship.
