Evaluating the potential of I-type cosmic spherules as a proxy for the Δ’17O of atmospheric O2 for reconstructing paleo-CO2 levels and GPP throughout the Phanerozoic
(2024-12-09)Entirely molten micrometeorites, termed I-type cosmic spherules, are micrometer to millimeter-sized remnants of extraterrestrial Fe, Ni-rich metal that can be recovered on Earth. I-type cosmic spherules acquire all oxygen ... -
Static and Dynamic Reservoir Characterization of the Heterogeneous Upper Jurassic Carbonate Reservoir Beneath the German Alpine Foreland Basin: A case study on a Premature Thermal Breakthrough Southeast of Munich
(2024-11-12)This study investigates the causes of an unexpected Premature Thermal Breakthrough (PTB) in a geothermal doublet located southeast of Munich. The PTB occurred after only three years of operation, which contradicts previous ... -
Laboratory studies of partially saturated infiltration dynamics in analog fractured porous rock systems - under consideration of fracture-matrix interaction and network geometry
(2024-08-09)Fractured porous rocks are abundant groundwater reservoir formations often covered by a thick, unsaturated zone. The interplay between fractures and rock matrix can significantly impede infiltration, particularly when the ... -
Temporal-Spatial Variabilities and Influencing Factors of Terrestrial Wet-Dry States and Vegetation Development: A Case Study in Northeast China
(2024-08-05)The number of hydroclimate disasters has increased dramatically since the late 20th century with profound changes in the environment. The Meteorological Drought Index facilitates long-term monitoring of wet-dry trends and ... -
High‐precision Strontium Isotope Measurements - From the Early Solar System to the Age of the Moon
(2024-07-12)Variations in the isotopic composition of extraterrestrial rocks provide crucial information about the nature and evolution of planetary building blocks, the Earth, and the Moon. In this thesis, strontium isotopic compositions ... -
Water level response to harmonic disturbances in confined aquifers: modeling, global sensitivity, and applications
(2024-06-13)In well-aquifer system, oscillatory water levels are often observed in monitoring wells when the aquifer is perturbed by harmonic disturbances, such as oscillatory pumping, ocean tide and seismic waves. In general, the ... -
Development of experimental and numerical models to predict the behavior of Kinetic Interface Sensitive (KIS) tracers for multiphase flow in porous media systems - A novel reactive tracer to measure fluid-fluid interfacial area in both static and dynamic conditions
(2024-04-12)An important aspect of understanding the behavior of a two-phase flow system is detecting and measuring the Fluid-Fluid Interfacial Area (FIFA). For example, in underground Gas/Oil/CO2 storage where two phases can co-exist, ... -
Fundamental data and conceptual framework for the exploration of geothermal resources in the Himalaya-Karakoram Orogenic belt, northern Pakistan
(2024-04-08)Northern Pakistan lies within the collision zone of the Indian and Asian plates comprising Himalaya, Kohistan, and Karakoram, with numerous hot springs associated with the Himalayan Geothermal Belt, extending 3000 km along ... -
Loess-palaeosol sections along the Rhône Rift Valley (SE France) as Late Quaternary palaeoenvironmental archives
(2024-03-05)Loess-palaeosol sections (LPSs) represent ideal archives for gaining knowledge of past climatic conditions and changes, as their intermediate loess deposits and buried palaeosols reflect climate conditions of their ... -
Effects of solid additives and inorganic ligands on the efficiency of metallic iron- based water treatment system
(2024-02-23)Metallic iron (Fe0) or zero-valent iron (ZVI) has been extensively used for water remediation during the past three decades. It has been proven to be effective in treating waters polluted with chlorinated aliphatics, dyes, ... -
Classification of main irrigated crop types towards sustainable development using Landsat and Sentinel data by GIS and remote sensing techniques in a semi-arid area in Tashkent Province, Uzbekistan
(2024-02-02)As the world population increases and cropland expansion occurs, there will be a high need in the food supply soon which will require higher agricultural yields. Crop yield estimation, management, and production assessments ... -
Understanding heat transport processes in shallow subground resulting from external and internal impacts
(2024-01-18)Heat conduction in the subsurface environment is the result of internal and external impacts and is governed by different forces in the short and long term. Externally, this phenomenon is related to daily temperature ... -
