Mit einem Multi-Modell-Ensemble wurde analysiert, wie sich der Klimawandel auf den Grundwasserhaushalt in Nordrhein-Westfalen (NRW) auswirkt. Hierzu wurden Projektionen der zukünftigen Grundwasserneubildung für insgesamt ... -
Modeling of methane migration from gas wellbores into shallow groundwater at basin scale
; ; (Environmental Earth Sciences, 2020-09-18)
Methane contamination of drinking water resources is one of the major concerns associated with unconventional gas development. This study assesses the potential contamination of shallow groundwater via methane migration ... -
Modeling Subsurface Hydrogen Storage With Transport Properties From Entropy Scaling Using the PC‐SAFT Equation of State
; ; ; ; ; (Water Resources Research, 2022-04-13)
Hydrogen is a promising alternative to carbon based energy carriers and may be stored in large quantities in subsurface storage deposits. This work assesses the impact of static (density and phase equilibria) and dynamic ... -
Modeling, simulation, and optimization of geothermal energy production from hot sedimentary aquifers
; ;; (Computational Geosciences, 2020-09-02)
Geothermal district heating development has been gaining momentum in Europe with numerous deep geothermal installations and projects currently under development. With the increasing density of geothermal wells, questions ... -
Monte Carlo Simulations as a Decision Support to Interpret δ15N Values of Nitrate in Groundwater
; ; (Groundwater, 2019)
Intense farming is often associated with the excessive use of manure or fertilizers and the subsequent deterioration of the groundwater quality in many aquifers worldwide. Stable isotopes of dissolved nitrate (δ15N and ... -
Moving Toward Standardized Toxicity Testing Procedures with Particulates by Dietary Exposure of Gammarids
Götz, Astrid; Imhof, Hannes K.;; Beggel, Sebastian (Environmental Toxicology and Chemistry, 2021-03-31)
Ecotoxicological effect assessment of particulate materials and sparingly soluble substances is an emerging field. Current standard toxicity tests of aquatic organisms are based on soluble substances which are added to the ... -
Multimodel Analysis of Future Land Use and Climate Change Impacts on Ecosystem Functioning
; ; ; ; ; ; (Earth's Future, 2019)
Land use and climate changes both affect terrestrial ecosystems. Here, we used three combinations of Shared Socioeconomic Pathways and Representative Concentration Pathways (SSP1xRCP26, SSP3xRCP60, and SSP5xRCP85) as input ... -
Multiproxy-Untersuchungen zur Paläoökologie und -hydrologie eines spätglazial- bis frühholozänen Flachsees im nordostdeutschen Küstengebiet (Glowe-Paläosee/Insel Rügen)
Lampe, Reinhard; Janke, Wolfgang; Schult, Manuela;; Lampe, Matthias (E&G – Quaternary Science Journal; Vol.65)
The paper presents results of multiproxy-investigations of a 3 m long sediment section from the Glowe Palaeolake, covering the period Pre-Bølling to the middle of the Preboreal. The Lateglacial and early Holocene landscape ... -
Natural and anthropogenic compaction in North Germany (Schleswig-Holstein): Verification of harmful subsoil compactions
; ; ; ; (Soil Use and Management, 2020)
Many soil types in the federal state of Schleswig-Holstein (North Germany) are naturally compacted in the subsoil due to pedo- or geogenic processes (42% of the area) but, due to anthropogenic impacts, the percentage of ... -
Natural hazards and climate change are not drivers of disasters
(Natural Hazards, 2021-11-10)
Many nations face challenges in assessing, understanding, and responding to the time-dependent nature of disaster risk. Changes in the intensity of occurrences of extreme events coupled with changes in vulnerability and ... -

Navigating through the jungle of information. Informational self-efficacy predicts climate change-related media exposure, knowledge, and behaviour
; ; (Climatic Change, 2020-11-25)
Climate change is a complex issue and understanding it is not an easy endeavour. An abundance of information is available through media and a lot of research has dealt with the question of how to best communicate this issue ... -
Non‐ and sub‐state climate action after Paris: From a facilitative regime to a contested governance landscape
; ; (Wiley Interdisciplinary Reviews: Climate Change, 2022-06-15)
The Paris Agreement marks a significant milestone in international climate politics. With its adoption, Parties call for non‐ and sub‐state actors to contribute to the global climate agenda and close the emissions gap left ... -
Number of Chamber Measurement Locations for Accurate Quantification of Landscape‐Scale Greenhouse Gas Fluxes: Importance of Land Use, Seasonality, and Greenhouse Gas Type
; ; ; ; ; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2022-09-23)
Accurate quantification of landscape soil greenhouse gas (GHG) exchange from chamber measurements is challenging due to the high spatial‐temporal variability of fluxes, which results in large uncertainties in upscaled ... -
Numerical analysis of the interaction between rockbolts and rock mass for coal mine drifts in Vietnam
(Univ. Freiberg (Sachsen), 2008)Since decades rockbolts are widely used as a support measure in mining and civil engineering. The presented literature review under special consideration of the situation in underground Vietnamese coal mines has revealed ... -
