Long periods of drought (2015 \, 2016 and 2018) are causing problems in the nutrient and oxygen balance due to extremely low discharges\, up to the formation of completely oxygen -free zones in the hyporheic interstitial. Conversely\, heavy precipitatio n leads to nutrients and soil particles entering soils in rives\, often wi th negative consequences for all those organisms that rely on an oxygenate d hyporheic interstitial. \;\nStreams are among the ecosystems particu larly affected by climate change. Long periods of drought (2015\, 2016 and 2018) are causing problems in the nutrient and oxygen balance due to extr emely low discharges\, up to the formation of completely oxygen-free zones in the hyporheic interstitial. Conversely\, heavy precipitation leads to nutrients and soil particles entering soils in rives\, often with negative consequences for all those organisms that rely on an oxygenated hyporheic interstitial.\nIn this project we aim at studying the temporal dynamics o f the hyporheic exchange and redox processes of the iron (and nitrogen) cy cle at the interface between groundwater and surface water at different hy drological conditions. The project is integrated into the Bavarian Researc h Network &ldquo\;aquaklif&rdquo\; studying the effect of climate stressor s on freshwater ecology.\nWe will work both at the field and laboratory sc ale and use a combination of state-of-the-art spectroscopic and microscopi c techniques in the lab and in-situ monitoring tools for field studies.\nM ultiple PhD projects are available to join our diverse\, interdisciplinary \, international and dynamic team of aquatic geochemists\, freshwater ecol ogists and hydrologists which will provide many opportunities for the cand idate to be creative and innovative\, and to work on a challenging and env ironmentally relevant topic combining various fields.Ideal candidates shou ld have a strong background in Bio- or Hydro-Geochemistry. Applicants must have the ability to work independently and in a team\, have excellent man agement and communication skills\, and be highly motivated to pursue inter disciplinary research. Good computer and language (English) skills are nec essary\, and field work experience highly beneficial.\nStart for successfu l applicants is at the earliest date possible or early 2019. The positions are open until filled. Employment (TVL E13\, 75%\, 3-4 years) will be arr anged by the University of Bayreuth. Disabled persons will be preferred in case of equal qualification.\nFor more information and to apply\, please send a CV\, motivation letter and overview of techniques and methods used in the past by email to: Prof. Dr. Stefan Peiffer (Stefan.Peiffer@uni-bayr euth.de) Department of Hydrology\, Bayreuth Center for Ecology and Environ mental Research\, University of Bayreuth\, Germany.\nMore information\, in cluding recent publications can be found on our website: www.hydro-uni-bay reuth.de\n \;\n \;\n \;\n \; DTSTART;TZID=Europe/Berlin:20181022T000000 DTEND;TZID=Europe/Berlin:20181201T235959 SUMMARY:Multiple PhD Projects - Biogeochemical Cycling TRANSP:TRANSPARENT END:VEVENT END:VCALENDAR
