The PhD project is embedded in</div><div>the BGI soil modelling group at the Max Planck Institute for</div><div>Biogeochemistry and in the Collaborative Research Centre (CRC) 'AquaDiva</div><div>– Understanding the links between surface and subsurface biogeosphere'.</div><div><br></div><div>The PhD project will focus on the transport of soil organic matter (SOM)</div><div>across the soil depth profile. The main project aim is to quantitatively</div><div>describe the transport of SOM across the soil profile and its relations</div><div>to land use (forest vs. grassland), site scale heterogeneity of water</div><div>flow, and event flows. You will do model development, building on our</div><div>experiences with the SOMPROF model. You will calibrate the SOMPROF model</div><div>at forest and at a grassland study site. Further you will develop</div><div>explicit links to water flow patterns and develop model schemes of event</div><div>flows. To this end, you will closely collaborate with another PhD</div><div>student studying hotspots of soil water movement induced by vegetation</div><div>canopies. By using model data integration with the collected data of</div><div>water flow hotspots within the sites, you will strive to understand the</div><div>effects of within-plot heterogeneity on SOM transport. In addition, you</div><div>will study scaling in order to use the insights about within-plot</div><div>heterogeneity again at site scale modelling.</div><div><br></div><div>The embedding CRC AquaDiva will focus on the important roles of water</div><div>(Aqua) and biodiversity (Diva) for shaping the structure, properties and</div><div>functions of the subsurface, defined as the zone that begins below the</div><div>highest density of plant roots (ca. 0.3 meters) and extends down into</div><div>the first aquifers (ca. 100 meters). Answering our questions about how</div><div>the critical zone interacts with matter and energy fluxes requires an</div><div>interdisciplinary research team that combines expertise in ecology,</div><div>microbiology, hydrogeology, soil science, geomorphology, geochemistry,</div><div>geology, geophysics, chemistry and information science. We are looking</div><div>for a highly motivated, active member of our group;; a team player who</div><div>works efficient, and is highly interested in interdisciplinary work</div><div>combining biogeochemistry and hydrogeology. You will be part of a young,</div><div>dynamic and supportive group, which promotes mutual exchange also with</div><div>other institutions and early participation in international and national</div><div>conferences and workshops.</div><div><br></div><div><br></div><div><b>Requirements:</b></div><div><br></div><div>- highly motivated scientist who holds a M.Sc. in soil science,</div><div>geo-ecology, hydrology or a related field </div><div>- experience in programming (python, matlab, R or other script languages) </div><div>- motivation to learn about numerical programming and statistics using R, </div><div>- willingness to take part in field work </div><div>- experiences in dynamical modelling, excellent knowledge of soil organic matter </div><div>turnover, - dissolved organic matter and water movement in the unsaturated zone will be assets.</div><div><br></div><div><br></div><div>The place of work is Jena, Germany - a city of science with a high</div><div>quality of living.</div><div><br></div><div>Salary is based on the guidelines for public service in accordance with</div><div>pay scale 13 (65%) of the German collective agreement for public service</div><div>(TVöD).
