the following positions will be available from 1 January 2015 or as soon as possible, subject to final approval by the funding organization

3 PhD students (E13 TV-L, 75%, temporary)

Job Description PhD student in geomorphology and soil science (Prof. Dr. Jörg Völkel)

The PhD student works at the Department of Geomorphology and Soil Science at TUM Weihenstephan (http://geomorphologie.wzw.tum.de/) in subproject 1 "Structure of the shallow subsurface and pedogenesis based on colluvial and alluvial processes" in close cooperation with the other project partners. The subproject requires interdisciplinary work in the fields of geomorphology and soil science. The field work will take place in Upper Bavaria and the Upper Palatinate. The sites are located in the TUM-Critical Zone Observatory (CZO-TUM, www.czo.wzw.tum.de), which is part of the International Critical Zone Environmental Network CZEN (www.czen.org) and closely connected to the TERENO network Helmholtz Association of German Research Centres (http://teodoor.icg.kfa-juelich.de/observ...APA_Observatory). Material translocation as a result of land use has a significant influence on soil development and C-content. The geomorphodynamics controlling erosion and deposition is among other factors largely controlled by relief and the shallow subsurface. To schematically describe the landscape in terms of these characteristics, sequences of soil profiles along geomorphic gradients in the form of catenas will be created. The classical orientation leads from the summit via the different slope sections (upper, middle, lower slope) to the alluvial plain. Via profile analysis (Pedon) catenas provide generalisable statements for a given type of landscape regarding soil genesis as well as material flows of all kinds. They are outstanding geoarchives for the reconstruction of system states and process changes in the course of changing parameters of the land use history. C-rich colluviums occur on a slope in the form of a cascade model as C-sinks and C-sources. Floodplain sediments show a multilayered structure. 14C-dating allows age determination and supports the accounting. For recent processes in the last decades Cs137 is used as a tracer. The shallow subsurface and its structure is prospected minimally invasive and illustrated using geophysical methods such as seismic refraction (SSR), electrical resistivity tomography (ERT) and ground penetrating radar (GPR). The location of catenas takes place in close collaboration with preset measuring locations of TP 3. Of particular importance for TP 2 is the change of lithology (carbonate-rich, well-buffered system in the Alpine foreland versus crystalline-siliceous, acid system in the Bavarian Forest).

Job Description PhD student in soil science with an emphasis on carbon (Prof. Dr. Ingrid Kögel-Knabner)

The PhD student works at the Department of Soil Science at TUM Weihenstephan (http://www.soil-science.com) in subproject 2 "Carbon and nitrogen conditions in soils formed in erosional-depositional environments" in close cooperation with the other project partners. The field work will take place in Upper Bavaria and the Upper Palatinate. The sites are located in the TUM-Critical Zone Observatory (CZO-TUM, www.czo.wzw.tum.de), which is part of the International Critical Zone Environmental Network CZEN (www.czen.org) and closely connected to the TERENO network Helmholtz Association of German Research Centres (http://teodoor.icg.kfa-juelich.de/
observatories/BAPA_Observatory). At selected profiles of the catenas, representing both alluvial and colluvial parts in the study area, the quantities and stocks of C (organic and inorganic) and N will be determined. By means of a combined physical fractionation according to particle size and density, the proportions of labile, intermediate and stable C are detected quantitatively. For the long-term sequestration of C in soil organo-minerally bound C is of particular importance. Moreover, the stoichiometric ratios of elements C and N are determined in relation to the C-storage capacity. The N-storage dynamics in topsoil and subsoil is investigated analogously. Therefore it is necessary for these soils to investigate the following aspects: humus content and condition in the soils of the various erosional-depositional environments, humus distribution in the soil profile depending on the parent material (crystalline vs. carbonatic-dolomitic), humus distribution and condition depending on the location within the erosion-accumulation-system in the catena, estimation of C-saturation as function of the mineralogical conditions and organic matter surface saturation.

Job Description PhD student / in C & N fluxes (Prof. Dr. Hans Peter Schmid)

The PhD student works in subproject 3 "Soil-atmosphere exchange of C and N-containing trace gases" in close cooperation with the other project partners. The subproject requires interdisciplinary work in the fields of biogeochemistry and micro-meteorology. The field work will take place in Upper Bavaria and the Upper Palatinate. The sites are located in the TUM-Critical Zone Observatory (CZO-TUM, www.czo.wzw.tum.de), which is part of the International Critical Zone Environmental Network CZEN (www.czen.org) and closely connected to the TERENO network Helmholtz Association of German Research Centres (http://teodoor.icg.kfa-juelich.de/observatories/
BAPA_Observatory). The topic of this PhD project is the investigation of C and N budgets in response to gradients of pedogenesis and the C and N content along colluvially and alluvially influenced catenas. The set-up and characterization of catenas is done by the partners in sub-projects 1 and 2. The exchange of the main C- and N-containing trace gases between the atmosphere and ecosystems (soils and vegetation) will be determined site-specific and quantitative using Eddy-Covariance- and cover technology. This work is done in close cooperation with the trace gas measurement program in the TERENO prealpine Observatory. These measurement results are accompanied and complemented by numerical modelling of the biological, biochemical and physical processes responsible for the exchange. Among other things, the effects of daily and seasonal cycles, weather, phenology, nutrient availability, as well as longer-term climatic trends on the carbon and nitrogen budgets of these ecosystems will become apparent. Apart from field work the work place for this PhD is on KIT-campus Alpine (Atmospheric Environmental Research) in Garmisch-Partenkirchen.
