Abstract: A comprehensive hydrogeological understanding of the deep Upper Jurassic carbonate aquifer, which represents an important geothermal reservoir in the South German Molasse Basin (SGMB), is crucial for improved and sustainable groundwater resource management. Water chemical data and environmental isotope analyses of δD, δ18O and 87Sr/86Sr were obtained from groundwater of 24 deep Upper Jurassic geothermal wells and coupled with a few analyses of noble gases (3He/4He, 40Ar/36Ar) and noble gas infiltration temperatures. Hierarchical cluster analysis revealed three major water types and allowed a hydrochemical zoning of the SGMB, while exploratory factor analyses identified the hydrogeological processes affecting the water chemical composition of the thermal water. Water types 1 and 2 are of Na-[Ca]-HCO3-Cl type, lowly mineralised and have been recharged 87 86 under meteoric cold climate conditions. Both water types show Sr/ Sr signatures, stable water isotopes values and calculated apparent mean residence times, which suggest minor water-rock Citation: Heine, F.; Zosseder, K.; interaction within a hydraulically active flow system of the Northeastern and Southeastern Central Einsiedl, F.

  • Groundwater Storage Dynamics in the World's
    Interactive comment on “Groundwater storage dynamics in the world’s large aquifer systems from GRACE: uncertainty and role of extreme precipitation” by Mohammad Shamsudduha and Richard G. Taylor Marc Bierkens (Referee #1) [email protected] Received and published: 2 January 2020 Reviewer’s comments are italicised, and our responses (R) and revisions (REVISION) are provided in normal fonts. General comments The authors use the results of three different GRACE-based TWS methods and 4 Land surface models to generate an ensemble of groundwater storage anomalies. These are subsequently analyzed by a non-parametric statistical method to separate seasonal signals from non-linear trends and residuals. The main message of the paper is that trends in GWS anomalies (ΔGWS), if existing, are non-linear in the vast majority of main aquifer systems and that rainfall anomalies play an important role in explaining these non-linear trends. I enjoyed reading the paper. I find that it is a well-written with an important message that deserves publication. However, I have a few comments. Moderate comments: 1. I find the lack of reference to estimates based on global hydrological models (GHMS) remarkable. The first spatially distributed global assessment of depletion rates where based on such models and, albeit indirect, should be used in the discussion. They are the basis for the “narratives on global groundwater depletion” that are mentioned in the discussion and the abstract (See https://iopscience.iop.org/article/10.1088/1748- 9326/ab1a5f/meta for an overview of these studies). This is the more remarkable, given that the authors do use Land Surface Models (LSMs) to estimate ΔGWS from GRACE ΔTWS.

  • Walking on Water- Global Aquifers
    16 March 2011 Walking on Water Mendel Khoo Researcher FDI Global Food and Water Crises Research Programme Gary Kleyn Manager FDI Global Food and Water Crises Research Programme Summary Aquifers play a key role in the provision of water for farming and for consumption by animals and humans. Almost all parts of the global landmass hide a subterranean water body. Aquifers are underground beds or layers of permeable rock, sediment or soil where water is lodged and can be accessed to yield water. This paper explores some of the major aquifers around the world and determines how countries are coping with increased water usage. Analysis Studying aquifers presents a number of problems, in part because scientists are yet to develop a complete picture of the globe’s aquifer systems; the sub-surface geology still holds mysteries. Further discoveries of aquifers and information on their connectivity with surface water can be expected in the future. The process should be similar to the way in which new discoveries of energy sources beneath the earth’s surface are still being made. An additional impediment lies in the different terms used to describe aquifers, some of them arising simply because of language differences. Aquifers do not fit into one neat category, as there are many variations to their form. The terminology for aquifers can include: underground water basins; groundwater mounds; lakes and parts of rivers; as well as artesian basins, which are confined aquifers contained under positive pressure. Hence, aquifers are not only located underground but some, or all, parts may also be found on the surface.

  • Aquifer Heat Storage: Abundance and Diversity of the Microbial Community with Acetate at Increased Temperatures
    Originally published as: Westphal, A., Kleyböcker, A., Jesußek, A., Lienen, T., Köber, R., Würdemann, H.

DOI: http://doi.org/10.1007/s12665‐016‐6356‐0 Aquifer heat storage: abundance and diversity of the microbial community with acetate at increased temperatures Anke Westphal1, Anne Kleyböcker1, Anna Jesußek2, Tobias Lienen1, Ralf Köber2, Hilke Würdemann1,3 1 GFZ German Research Centre for Geosciences, Section 5.3 Geomicrobiology, 14473 Potsdam, Germany 2 Christian-Albrechts-Universität zu Kiel, Institute of Geosciences, 24118 Kiel, Germany 3 Environmental Technology, Water- and Recycling Technology, Department of Engineering and Natural Sciences, Merseburg University of Applied Sciences, 06217 Merseburg, Germany Abstract The temperature affects the availability of organic carbon and terminal electron acceptors (TEA) as well as the microbial community composition of the subsurface. To investigate the impact of thermal energy storage on the indigenous microbial communities and the fluid geochemistry, lignite aquifer sediments were flowed through with acetate-enriched water at temperatures of 10 °C, 25 °C, 40 °C, and 70 °C in sediment column experiments. Genetic fingerprinting revealed significant differences in the microbial community compositions with respect to the different temperatures. The highest bacterial diversity was found at 70 °C. Carbon and TEA mass balances showed that the aerobic degradation of organic matter (OM) and sulfate reduction were the primary processes that occurred in all the columns, whereas methanogenesis only played a major role at 25 °C. The methanogenic activity corresponded to the highest abundance of an acetoclastic Methanosaeta concilii-like archaeon and the most efficient degradation of acetate.
