Pore water and groundwater from the containment providing rock zone (CRZ) and surrounding aquifers provide the initial chemical conditions and boundaries for reactive transport simulations of radionuclide migration in the context of the disposal of highly radioactive waste. Hydrochemical differences between these units cause gradients in the pore water profile across the CRZ, which affect...
Since 2000, the Groß Schönebeck site has served as a multidisciplinary research platform, investigating the extraction of geothermal energy via a ~4.4 km doublet well system. As part of the TRANSGEO project, a study was conducted to explore alternative geothermal development options at the site. The study considered the potential of utilising the existing infrastructure for electricity...
Previous hydrological research has focused on the physical basis of flood events. Thereby hydrodynamic models are established often ignoring societal and economic factors. This omission can lead to mischaracterization of flood events. Recently, the pathways between flooding and economic damage have therefore been integrated into the models. However, impacts on physical and mental health are...
Population growth, climate change, and a lack of infrastructure have contributed to an increase in water demand and groundwater exploitation in urban and rural Afghanistan, resulting in significant ground subsidence. Based on a 7-year-long Sentinel-1 radar-interferometric time-series (2015–2022), we assess country-wide subsidence rates. Of particular focus are urban Kabul and the growing...
Global Navigation Satellite Systems (GNSS) are one of the most important techniques for positioning, navigation and the realization of the International Terrestrial Reference Frame (ITRF), which forms the basis for many coordinate-related applications in the geosciences. The basic principle of GNSS is to measure the time difference between the transmission of a microwave signal at the...
The growing volume and frequency of streaming remote sensing data present challenges for real-time modeling and forecasting. Traditional batch learning is unsuitable for such dynamic environments, while standard online learning frameworks, though more adaptive, face key limitations. These include one-step-ahead forecasting, prediction latency due to retraining dependencies, and vulnerability...
The solar wind, a stream of charged particles originating from the Sun, poses significant risks to technology and astronauts. It is driven by large structures on the solar surface like coronal holes and active regions, which can be identified in extreme ultra-violet (EUV) solar images several days before they become geoeffective. In this work, we propose to use a distributional regression...
Since the last eruption of the Laacher See volcano (LSV) in the East Eifel volcanic field (EEVF) around 12.9 kyr ago, the volcanic activity beneath the LSV can still be traced by several gas emissions in the lake and its surroundings. This continuous gas flux is related to CO2 originating from the magmatic system in the upper mantle to the shallow crust at about 10 - 30 km depth, from where...
The collision between the Indian and Eurasian Plates induces simultaneous widespread crustal shortening and extension in the Tibetan Plateau. Collision-induced crustal deformation at regional, orogenic scale is compartmentalized into networks of active faults of locally diverse tectonic regimes. Yet, the correlation between triaxial strain and deformation patterns requires better...
Marine carbon dioxide removal (mCDR) poses profound governance challenges at the ocean–climate nexus. While often framed through technical and legal lenses, mCDR governance risks reproducing historical inequities by sidelining Global South actors, privileging dominant epistemologies, and neglecting justice concerns. This transdisciplinary PhD project examines how equity is defined,...
