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 ... -
Measuring and tracking suspended sediment on tidal flats and inundated marshland: Relevance for vertical accretion rates and coastal protection measures on the North Frisian Halligen
(2021-04-13)Inhabited coastal areas around the world have to deal with sea level rise (SLR) and its likely consequences such as increasing natural hazards like heavy storms, flooding events and coastal lowland loss by drowning over ... -
Investigating the dielectric profiling of ice cores
(2021-02-12)The polar regions are important components of the Earth's climate system, as these areas are the main sources of fresh water on Earth. Any conflicts in that system can affect people's lives in different ways. Numerous ... -
Monitoring forest fragmentation and carbon storage in the Cerrado Biome of Mato Grosso using optical and SAR satellite images
(2021-01-15)Several studies suggested that forest fragmentation, which is an effect of deforestation, and edge effect have an impact on the biomas and carbon stock in tropical forest. For Amazon and Atlantic Forest biomes, most studies ... -
Urbanisation, Land Use and Soil Resource: Spatio-Temporal Analyses of Trends and Environmental Effects in Two Metropolitan Regions of Ghana (West Africa)
(2020-12-23)With more than half of the world’s population already urbanised, global sustainability is partly hinged on how the urbanisation process is impacting the natural environment. Therefore, it is important to characterise, ... -
Space-time modelling of seasonal soil moisture for improved crop production – the case of the Guinea savannah region, Ghana
(2020-12-17)The upsurge in advocacy for food security in SSA implies the urgent need for improved sustainable adaptation measures that can boost food-crop production. This is of utmost concern, because, over the past decades, food ... -
Numerical modelling of single- and multi-phase flow and transport processes in porous media for assessing hydraulic fracturing impacts on groundwater resources
(2020-05-28)The environmental footprint of hydraulic fracturing has gained substantial attention in the water – energy nexus as the technology is relatively new and its long-term impacts are not thoroughly understood. Of primary ... -
Pigments, Colours and Patterns - The contribution of eumelanin and pheomelanin to molluscan shell ornamentation with a special focus on the terrestrial snail Cepaea nemoralis
(2020-02-25)In recent years interest into molluscan pigments increased. But a lot of techniques have to be adapted to be usable with often difficult molluscan tissues and shell material. A comprehensive approach needs to encompass ... -
Late Palaeozoic to Early Mesozoic evolution of the Palaeotethys in Turkey: Insights from the Karaburun Peninsula and the Konya Complex
(2019-11-08)The greater aim of this PhD thesis is to test the current palaeotectonic models for the Late Palaeozoic to Early Mesozoic evolution of the Palaeotethys in the Eastern Mediterranean. Therefore, siliciclastic rocks from two ... -
Air Surface Temperature Estimation Using MODIS Land Surface Temperature Data in Northwest Vietnam
(2019-07-26)There is increasing demand for air surface temperature (Ta) data that can capture information for a large area or for a region, since this kind of data is an important parameter for a wide range of applications. However, ... -
Soil Properties Mapping and Land Evaluation for Potential Agricultural Land Use Types in A Luoi district, Thua Thien Hue province, Central Vietnam
(2019-07-03)Agriculture plays an essential role in Vietnam, especially central Vietnam, which is the least developed economically and socially compared to the other regions. Many administrative levels in Vietnam have implemented ... -
The development of the Dangerous Grounds and Palawan Island in the southeastern part of the South China Sea, deduced from carbonate formations
(2019-03-15)The South China Sea is a quite narrow Cenozoic ocean basin. It is located between China in the north, Vietnam in the west, Malaysia and Brunei in the southeast and the Philippines in the north and northeast. Rifting in the ... -
Analyses of hydrological and hydrochemical fluxes in selected catchments of the Cerrado and Amazon biomes
(2019-03-12)On many levels, there is a lack of understanding regarding the impacts of deforestation on water resources and soil properties in the Amazon-Cerrado ecotone, where the Amazonian agricultural frontier is mostly present. ... -
Chemical water quality in Selenge River Basin in Mongolia: spatial-temporal patterns and land use influence
(2018-10-18)Water is essential for life and for all human activities but also for preserving the environment and its resources. Rapidly growing population, intensification of agriculture, industrialization, urbanization, development ... -
Fast X-ray diffraction crystal size distribution analysis
(2018-09-11)Fast X-ray Diffraction Crystal Size Distribution analysis (FXD-CSD) constitutes a novel method to determine volume-based crystal size distributions (CSD) of crystalline powders or polycrystalline materials in the lower µm ... -
Formation and preservation of abiotic organic signatures vs. lipid biomarkers—experimental studies in preparation for the ExoMars 2020 mission
(2018-06-22)Molecular organic biomarkers have widely been used to track life through Earth’s history, and they became increasingly important in the search of potential (remnants of) life on Mars. The Mars Organic Molecule Analyzer ... -
On the significance and predictability of geological parameters in the exploration for geothermal energy
(2018-05-02)Sufficient reservoir permeability is essential to exploit heat resources for geothermal energy. Reliable prediction of permeability and in consequence flow rate in a deep geothermal reservoir is difficult to predict because ... -
Tracer compounds in geothermal reservoirs: Improving the outcome quality of a tracer test
(2018-04-20)In a tracer test, applied tracers are introduced and transported with a working fluid so that the tracer response signals can be used to determine the target parameters of the aquatic system, such as temperatures, flow ... -
Diversity patterns of herbaceous angiosperms along gradients of elevation and forest use intensity in Central Veracruz, Mexico
(2017-12-20)Terrestrial herbs are an important element in tropical forests; however, there is a lack of research on their diversity patterns and how they respond to different forest use intensities. Studying the richness and distributional ... -
