(2002-05-08)For the central Siberian study area a postprocessing of SAR (Synthetic Aperture Radar) remote sensing data from ERS (European Remote Sensing Satellite) and JERS (Japanese Earth Resources ... -
Application of Garnet in Sedimentary Provenance Analysis
(2015-11-13)This PhD thesis investigates the application of heavy minerals in sedimentary provenance analysis, with the main focus on garnet geochemistry. The work is mainly based on an intensive literature study, fieldwork, conventional ... -
Applying Organic Compounds as Indicators in Innovative Monitoring Strategies
(2019-08-07)Today, demands on water quality are diverse and strongly differ by water use related criteria. Additionally, the complex topic of water quality is of increasing importance for citizens and is therefore often emotionally ... -
Assessing the formation and preservation of organic signatures in extreme environments in the context of the ExoMars 2020 rover mission
(2019-09-20)The search for extraterrestrial life is one of the greatest scientific quests of our time. The ESA/Roscosmos ExoMars 2020 rover mission seeks to find evidence for past or modern life on Mars by investigating (sub-)surface ... -
Assessment of Drought in Grasslands: Spatio – Temporal Analyses of Soil Moisture and Extreme Climate Effects in Southwestern Mongolia
(2021-06-28)Soil moisture plays an essential key role in the assessment of hydrological and meteorological droughts that may affect a wide area of the natural grassland and the groundwater resource. The surface soil moisture distribution ... -
Assessments of phenotypic variations and variability as a tool for understanding evolutionary processes in echinoids
(2016-07-20)The following three chapters can be regarded as thematic complexes of studies on phenotypic variations and variability in order to elucidate their origins on a systematic hierarchy-level in echinoids. Chapter 2 seeks ... -
Auslaugung anorganischer Schadstoffe aus Abfall- und Altlastmaterialien
(2005-06-22)Ten waste and refuse materials were filled into small lysimeters in layers of 50 cm thickness. They were covered with three top-soils of varying pH (sandy forest soil, sandy arable soil and ... -

(2013-12-13)Lower Saxony (total land area about 46,500 km2) constitutes one of the most important agricultural areas in Germany and thus within Europe. However today, there exists no comprehensive account on the impacts of climate ... -
Auswirkungen von ENSO-Trockenperioden und Landnutzungspraktiken auf die Dynamik von C, N und P in einem tropischen Regenwald und in Agroforst-Systemen in Zentral-Sulawesi, Indonesien
(2010-02-03)This thesis aimed to characterize the response of nutrient (C, N, P) and cation (Ca2+, K+, Mg2+, Na+) soil pools and dynamics to experimental drought and land-use practices in Central ... -
Automated data processing and numerical methods for travel-time based hydraulic tomography
(2020-08-13)Travel time based hydraulic tomography is a useful and promising technique for reconstructing the spatial distribution of aquifer hydraulic properties (e.g., hydraulic diffusivity). Simultaneous Iterative Reconstruction ... -
Backtracking approaches for the delineation of contamination sources
(2013-12-13)Contaminated groundwater poses a serious threat to drinking water resources all over the world. Even though contaminated water might be detected in observation wells, a proper clean-up is often only successful if the source ... -
