Carbon Dioxide un ultrapotassic silicate melts: Experimental insights on solubility and decompression induced vesicle nucleation
(2021-10-01)Until today, the explosivity of volcanic eruptions cannot be forecasted by even the most modern monitoring techniques. The processes causing these events, endangering the lives of millions of people, happen deep inside the ... -
Geoecological analysis of forest distribution and post-disturbance tree regrowth in the forest-steppe of central Mongolia
(2021-09-09)The Mongolian forest-steppe is an ecotone at the transition between the Siberian Taiga in the north and the Gobi Desert in the south. The highly continental, semiarid climate magnifies the importance of water availability ... -
Microbial alteration of geochemical proxies in finegrained carbonate sediments during early diagenesis
(2021-07-27)Fine-grained carbonate sediments play a crucial role in the global carbon cycle and are an exceptional record of past environmental conditions. Major paleoenvironmental constraints, derived from stable isotope and trace ... -
Forest Landscape Restoration and Ecosystem Services in A Luoi District, Thua Thien Hue Province, Vietnam
(2021-07-23)Abstract The Government of Vietnam has invested efforts to increase the forest cover, and to conserve biodiversity through different forest development projects and programs. Losing natural forests and landscapes in the ... -
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 ... -
Derivation of forest inventory parameters from high-resolution satellite imagery for the Thunkel area, Northern Mongolia. A comparative study on various satellite sensors and data analysis techniques.
(2021-06-03)With the demise of the Soviet Union and the transition to a market economy starting in the 1990s, Mongolia has been experiencing dramatic changes resulting in social and economic disparities and an increasing strain on its ... -
Hydrochemical and environmental isotope study of the geothermal water in Mae Chan (North) and Ranong (South) geothermal areas in Thailand
(2021-05-28)The exploration and development of geothermal resources in Thailand have been investigated for electricity generation since 1946. In total, 112 hot springs are manifested which mostly scattered at the granite body from the ... -
Ultrasonic tomography for the characterization of the weathering state of marble
(2021-05-25)The present thesis investigated the application of ultrasonic tomography to evaluate the weathering condition of different marble varieties. Ultrasound analysis is a non-destructive examination method which is often used ... -
Late Paleogene - Early Neogene Abandoned Rift along the River Nile, Egypt
(2021-04-30)The River Nile is one of the major fluvial systems in the world. The Egyptian Nile has been the most studied part of the river. However, the origin, tectonic style and geodynamic evolution of the Nile are still widely ... -
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 ... -
Agrarian change and hydro-social transformations. The socio-natural production of water, risk and inequality in Jambi province, Indonesia
(2021-02-23)The production of palm oil, pulpwood and rubber has caused a large-scale expansion of agro-industrial plantation systems in Southeast Asia in recent years. This development is highly contested and has sparked conflict over ... -
Cretaceous to Cenozoic thermo-tectonic evolution and provenance analysis of the basement and some sedimentary successions northeast of the Songliao Basin, NE China
(2021-02-23)The major aim of this PhD thesis is to explore the post-Early Mesozoic thermo-tectonic evolution and provenance analysis of the area of satellite basins to the east of the Songliao basin in NE China, covering a huge area, ... -
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 ... -
