CRM-geothermal Database: Geoscientific and Geochemical Data on Geothermal Systems, with Emphasis on Fluids and Critical Raw Materials in Europe and Eastern Africa

The CRM-geothermal database was created within the Horizon Europe CRM-geothermal project (Grant Agreement No. 101058163) to support the assessment of geothermal systems as sources of both renewable energy and critical raw materials (CRMs). The primary purpose of data collection was to compile, harmonise, and make openly available geoscientific and geochemical data relevant to the occurrence, enrichment, and potential co-production of CRMs from geothermal environments in Europe and East Africa. The database integrates legacy data compiled from peer-reviewed literature, national geological and geothermal databases, and previous European research projects (notably REFLECT), together with new data generated by project partners through field sampling and laboratory analyses. Sampling campaigns targeted geothermal wells and surface manifestations in selected regions, including Türkiye, the East African Rift (Kenya, Tanzania, Malawi), Cornwall (UK), and Iceland. Laboratory analyses include major ion chemistry, trace and critical element concentrations, mineralogical composition, and gas data, determined using methods such as ICP-MS, XRF, and XRD. All records were harmonised using a unified metadata schema, standardised units, and consistent reporting formats. Quality control involved automated validation routines and manual expert review. Each record includes spatial coordinates, sampling context, analytical method, references, and a quality flag indicating data origin and traceability. The database is provided as a structured Excel file and contains interconnected datasets on geothermal wells, fluids, rocks, gases, and mineral precipitates. In total, the dataset comprises 9,773 records covering a wide range of geological settings, from volcanic and metamorphic systems to sedimentary basins. The CRM-geothermal database is FAIR-aligned, openly available, and intended for reuse in geothermal research, resource assessment, and studies on the sustainable co-production of geothermal energy and critical raw materials. Method: The CRM-geothermal database was compiled using a combined approach integrating literature-based data collection, database harmonisation, and new data generation through field sampling and laboratory analysis. Legacy data were collected from peer-reviewed scientific publications, national geological and geothermal databases, technical reports, and previous European research projects, with a particular emphasis on the REFLECT project. Relevant parameters were manually extracted, digitised where necessary, and cross-checked against original sources to ensure consistency and traceability. New data were generated within the CRM-geothermal project through targeted sampling campaigns at selected geothermal sites in Europe and Eastern Africa. Samples of geothermal fluids, rocks, gases, and mineral precipitates were collected from wells and surface manifestations following standard geochemical sampling protocols. Laboratory analyses were performed by project partner institutions using established analytical techniques, including inductively coupled plasma mass spectrometry (ICP-MS) for trace and critical elements, X-ray fluorescence (XRF) for bulk chemical composition, and X-ray diffraction (XRD) for mineralogical characterisation. Gas compositions were determined using gas chromatography and noble gas mass spectrometry where applicable. Detection limits and analytical uncertainties follow laboratory-specific standards and are documented where available. All data were harmonised using a unified metadata schema. Units, parameter names, and reporting formats were standardised, and spatial information was converted to WGS 84 decimal degrees. Quality control was applied through automated validation scripts checking metadata completeness, coordinate validity, and numerical plausibility, followed by manual expert review to ensure scientific coherence and correct sample attribution. The final dataset was organised into interconnected thematic tables (wells, fluids, rocks, gases, and scales) and exported as a structured Excel file for dissemination. Each record includes references, analytical method information, and a quality flag indicating data origin and traceability. Technical Info: The CRM-geothermal data publication is provided as a structured multi-sheet Excel (XLSX) file representing a curated snapshot of the CRM-geothermal database at the time of publication. The dataset was generated through controlled export workflows following data validation and harmonisation. The Excel file contains separate worksheets for thematic data tables (wells, fluids, rocks, gases, and mineral precipitates). Each worksheet preserves unique identifiers, standardised metadata fields, and cross-references between related records, allowing the dataset to be used independently of any external system or software platform.

Forschergruppe (FOR) 1320: Crop Sequence and Nutrient Acquisition from the Subsoil, Water as medium for nutrient distribution: Monitoring water distribution between subsoil and topsoil considering roles of biopores and plants, by MRT and pressure probes (WatMed)

Magnetic resonance tomography (MRT) on microcosm soil cores (200 mm Ø) used for CeMiX, comprising naturally stacked subsoil down to 700 mm plus topsoil from CeFiT, will be implemented at a laterally partially open Split 1.5 T magnet, with intended final in-plane spatial resolution of 200 Micro m. Three-dimensional biopore distributions and dynamics of their formation within the cores will be determined non-invasively and compared to complementing CT analyses of SP 2. One major aim is a non-invasive differentiation of the biopores into earthworm- and root system-originating ones and currently air-, water-, root- and earthwormfilled ones, based on NMR relaxation parameters. Attempts will additionally be made to classify different wall coatings of the biopores with regard to their water affinity. Dynamics of water distribution within the microcosm core and its biopore structures, starting from initial values taken from CeFiT (SP 3), will be documented with an in-plane resolution of 5 mm, in parallel to measurements of root growth dynamics for calculation of biomass and root surface area. Special emphasis will be put on the role of the plant root system for a re-distribution of water/D2O (and solutes) between different soil layers. Finally we will attempt MRT-controlled sample collection from the microcosm cores, to get - together with our research unit partners of SPs 4-8 - repeated access to minimally invasively acquired data on nutrient and microorganism distributions in concert with non-invasively collected water and root distribution data as a basis for dynamic modelling of water and solute circuits in SP 10. Beside the microcosm cores, flat rhizotrons as used in SP 3 will be employed to enable measurements of root and shoot hydrostatic pressure profiles with pressure probes, in addition to MRT measurements. In this way water distributions and corresponding driving forces and growth dynamics will be measured altogether in a minimally invasive manner.

Moosmonitoring 1995/96, Untersuchungen der Schwermetallgehalte in Moosen, Lithium in Moosen, Einzelelementkarten

In der Bundesrepublik Deutschland wurden von 1990 bis 2005 in fünfjährigem Abstand sowie in den Jahren 2015/16 und 2020/21 Untersuchungen zur Bestimmung der Inhaltsstoffe von Moosen durchgeführt. Schwerpunkt war die Analyse von Schwermetallen, ab 2005/06 auch von Sticksoff. Seit 2015/16 wurde das Stoffspektrum auf persistente organische Stoffe (POP) und Mikroplastik ausgeweitet. Dieses „Moosmonitoring“ ist der deutsche Beitrag zum europäischen Moosmonitoringprogramm, welches durch das „Internationale Kooperativprogramm zur Wirkung von Luftverunreinigungen auf die natürliche Vegetation und auf landwirtschaftliche Kulturpflanzen“ („International Cooperative Programme on Effects of Air Pollution on Natural Vegetation and Crops“, kurz: ICP Vegetation) der Genfer Luftreinhaltekonvention (Convention on Long-range Transboundary Air Pollution, CLRTAP) koordiniert wird. Mit der Durchführung der einzelnen Probenahmekampagnen sowie der Auswertung der Untersuchungsergebnisse wurden durch das Umweltbundesamt (UBA) wechselnde Institutionen beauftragt, so die Bundesanstalt für Geowissenschaften und Rohstoffe (BGR) mit dem Moosmonitoring 1995/96. Die Ergebnisse der nachfolgenden Monitoringjahre hat das Umweltbundesamt veröffentlicht. Sie sind abrufbar unter https://www.umweltbundesamt.de/daten/luft/bioindikation-von-luftverunreinigungen. Das Moos-Monitoring 1995/96 ist mit 1026 Standorten neben dem Moos-Monitoring 2000 das mit der größten Probenahmedichte und mit 40 analysierten Elementen das mit dem größten Untersuchungsspektrum. Obwohl die in den Jahren 1998 und 1999 fertiggestellten Forschungsberichte (Siewers & Herpin, 1998; Siewers, Herpin & Straßburg, 1999) eine Auswertung (Kurzbeschreibung, statistische Maßzahlen, Verteilungskarten) aller 40 analysierten Elemente enthalten, wurden bislang nur die Daten von 12 der analysierten Elemente veröffentlicht. Darüber hinaus wurden im Jahr 2007 die im Ergebnis der Analytik vorliegenden Rohdaten aus den Laboratorien einer Neubewertung unterzogen. Daraus resultiert eine Reihe von Fehlerkorrekturen, das auswertbare Elementspektrum konnte auf 42 Elemente erweitert werden. Auch die Ergebnisse dieser Neubewertung sind bislang unveröffentlicht. Die ergänzende Bearbeitung der Daten mit modernen Verfahren bringt eine zusätzliche Aufwertung dieser. Die Downloads zeigen die Verteilung der Lithiumgehalte in Moosen in vier verschiedenen farbigen Punkt- und Isoflächenkarten. Die Legenden der Karten sind wahlweise in der Maßeinheit µg/g oder in einer an den Gehaltsbereich des dargestellten Elements angepassten Maßeinheit abrufbar.

Naturfasern

Faserpflanzen gehören zu den ältesten nachwachsenden Rohstoffen. Eine große Anzahl von Pflanzenarten enthalten vor allem aus Zellulose bestehende Fasern mit unterschiedlichen Eigenschaften. Die größte wirtschaftliche Bedeutung hat die Baumwolle erlangt, aber auch Jute, Sisal, Flachs, Hanf und Kokosfasern spielen eine wichtige Rolle. Im Freistaat Sachsen ist in den Regionen Erzgebirge, Oberlausitz und Vogtland der Flachs (Faserlein), außerhalb der höheren Mittelgebirgslagen auch der Hanf anbauwürdig. Flachs und Hanf sind botanisch und bezüglich ihrer Wuchsform sehr unterschiedliche Pflanzen. Verwendung finden Kurz- und Langfasern in Mischgarnen, Verbundwerkstoffen, Geotextilien, Dämmstoffen, Verpackungsmaterialien, technischen Textilien, Asbestersatz.

Trace element contents for the <2 μm, 2-20 μm and bulk fractions from LGM European loess sequences

Trace element contents in microg/g measured on the <2 microns, 2-20 microns size fractions and bulk samples from LGM European loess sequences. Samples were crushed in an agate mortar and trace element concentrations were measured following Chauvel et al. (2011). Reproducibility for trace element analyses is better than 5% based on repeat measurements, and the accuracy is also better than 5%, based on the analyses of international rock standards (JSD-1, JSD-3 and LKSD-1.

Adaptations and counter-adaptations in the coevolutionary arms race of a baculovirus and its insect host

Cydia pomonella granulovirus (CpGV, Baculoviridae) is one of the most important agents for the control of codling moth (CM, Cydia pomonella, L.) in both biological and integrated pest management. The rapid emergence of resistance against CpGV-M, which was observed in about 40 European CM field populations from 2003 on, could be traced back to a single, dominant, sex-linked gene. Since then, resistance management has been based on mixtures of new CpGV isolates (CpGV-I12, -S), which are able to overcome this resistance. Recently, resistance even to these novel isolates was observed in CM field populations. This resistance does not follow the described dominant, sex-linked inheritance trait. At the same time, another isolate CpGV-V15 was identified showing high virulence against these resistant populations. To elucidate this novel resistance mechanism and to identify the resistance gene(s) involved, we propose a comprehensive analysis of this resistance on the cellular and genomic level of codling moth. Because of the lack of previous knowledge of the molecular mechanisms of virus resistance in insects, several different and complementary approaches will be pursued. This study will not only give an in-depth insight into the genetic possibilities for development of baculovirus resistance in CM field populations and how the virus overcomes it, but can also serve as an important model for other baculovirus-host interaction systems.
