This dataset contains C. wuellerstorfi stable carbon isotope values binned by marine isotope stage from ODP Site 162-807 and ODP Site 162-982 that span the last 4.5 million years (Feng et al. 2022; Venz et al. 1999, 2002; Hodell & Venz-Curtis 2006). This isotope gradient reflects the accumulation of respired and disequilibrium carbon in the deep Pacific ocean relative to the North Atlantic. Also included are binned probstack δ18O (Ahn et al., 2017) and ΔGMST (Clark et al., 2024) values for comparison to the binned stable carbon isotope values.
This study reports a precisely dated pollen record with a 20-year resolution from the varved sediments of Lake Mondsee in the north-eastern European Alps (47°49′N, 13°24′E, 481 m above sea level). The analysed part of core spans the interval between 1500 BCE and 500 CE and allows changes in vegetation composition in relation to climatic changes and human activities in the catchment to be inferred. Intervals of distinct but modest human impact are identified at ca. 1450-1220, 740-490 and 340-190 BCE and from 80 BCE to 180 CE. While the first two intervals are synchronous with prominent salt mining phases during the Bronze Age and Early Iron Age at the nearby UNESCO World Heritage Site of Hallstatt, the last two intervals fall within the Late Iron Age and Roman Imperial Era, respectively. Comparison with published records of extreme runoff events obtained from the same sediment core shows that human activities (including agriculture and logging) around Lake Mondsee were low during intervals of high flood frequency as indicated by a higher number of intercalated detrital event layers, but intensified during hydrologically stable intervals. Comparison of the pollen percentages of arboreal taxa with the stable oxygen isotope and potassium ion records of the NGRIP and GISP2 ice cores from Greenland reveals significant positive correlations for Fagus and negative correlations for Betula and Alnus. This underlines the sensitivity of vegetation around Lake Mondsee to temperature fluctuations in the North Atlantic as well as to moisture fluctuations controlled by changes in the intensity of the Siberian High and the North Atlantic Oscillation (NAO) regime.
In the Earth, the dynamo action is strongly linked to core freezing. There is a solid inner core, the growth of which provides a buoyancy flux that drives the dynamo. The buoyancy in this case derives from a difference in composition between the solid inner core and the fluid outer core. In planetary bodies smaller than the Earth, however, this core differentiation process may differ - Fe may precipitate at the core-mantle boundary (CMB) rather than in the center and may fall as iron snow and initially remelt with greater depth. A chemical stable sedimentation zone develops that comprises with time the entire core - at that time a solid inner core starts to grow. The dynamics of this system is not well understood and also whether it can generate a magnetic field or not. The Jovian moon Ganymede, which shows a present-day magnetic dipole field, is a candidate for which such a scenario has been suggested. We plan to study this Fe-snow regime with both a numerical and experimental approach. In the numerical study, we use a 2D/3D thermo-chemical convection model that considers crystallization and sinking of iron crystals together with the dynamics of the liquid core phase (for the 3D case the influence of the rotation of the Fe snow process is further studied).The numerical calculations will be complemented by two series of experiments: (1) investigations in metal alloys by means of X-ray radioscopy, and (2) measurements in transparent analogues by optical techniques. The experiments will examine typical features of the iron snow regime. On the one hand they will serve as a tool to validate the numerical approach and on the other hand they will yield important insight into sub-processes of the iron snow regime, which cannot be accessed within the numerical approach due to their complexity.
Sanukitoids, also referred to as high-Mg diorites, are a distinctive type of igneous rock from the late Archean-early Proterozoic, and are characterised by enrichment in both compatible elements (e.g. Mg, Ni, Cr) and incompatible elements (e.g. Ba, Sr, light rare earth elements). Their geochemistry is typically interpreted as recording petrogenesis of their parental magmas via interaction between mantle peridotite and recycled crust-derived component (e.g. metabasite melts, sediment melts, aqueous fluids), and is often considered to be "transitional" between that of Archean sodic tonalite-trondhjemite-granodiorite (TTG) suites and post-Archean potassic granites. This dataset presents a global compilation of all Archean-Paleoproterozoic rocks that have been described as "sanukitoid" in published literature, and consists of over 3600 individual samples. Whole rock major and trace element concentrations, radiogenic isotope compositions and stable isotope compositions are compiled in the dataset alongside reported magmatic ages of the samples. The dataset is provided both as an Excel workbook divided by craton (file: 2025-003_Spencer-et-al_Sanukitoid-Compilation.xlsx) and as a single CSV file (file: 2025-003_Spencer-et-al_Sanukitoid-Compilation.csv). Sanukitoid magmatism has been described on almost every Archean craton globally. Most reported sanukitoid magmatism occurred during the late Mesoarchean-Neoarchean (2.95 - 2.5 Ga), with another peak in sanukitoid magmatism in the mid-Paleoproterozoic (2.2 - 2.0 Ga). Older sanukitoid occurrences dating back to the Paleoarchean (>3.2 Ga) are also described in the literature.
This dataset contains dissolved inorganic/organic carbon (DIC/DOC) concentrations, its stable isotope ratios (δ13CDIC/DOC), partial pressure of carbon dioxide in the water column pCO₂(aq) (pCO2(aq)) and area-integrated CO₂ emission rates derived from flux calculations (FCO2; g C d⁻¹), along with corresponding parameters (temperature, pH, calcium, bicarbonate) collected from the Danube River and its key tributaries during five seasonal sampling campaigns in 2023 and 2024. Water samples were collected using a weighted 2 L sampling bottle submerged 1–2 meters below the surface, with sampling conducted from the river center via bridges or passenger boats, and occasionally from the riverbank. In situ temperature measurements were taken with a multiparameter instrument (HQ40d, HACH™, Loveland, CO, USA). δ13ODIC/DOC was analyzed using a OI Analytical Aurora 1030W-IRMS. This dataset is providing valuable insights into carbon dynamics in a large river system and support investigations of biogeochemical cycling. It further can inform ecosystem management and conservation strategies under changing environmental conditions.
This project is aimed at the characterization of the systemic reprogramming in barley, which modulates the compatible interaction with the biotrophic leaf pathogen Blumeria graminis f.sp. hordei upon root infestation with the mutualistic endophyte Piriformospora indica. We have recently shown that the basidiomycete P. indica - upon successful establishment in the roots - reprograms barley to salt stress tolerance, resistance to root diseases and higher yield (Waller et al., 2005). Successful powdery mildew infections in barley leaves are also disturbed by the mutualistic fungus. These processes are associated with a strong change in plant metabolism, especially with a drastic alteration of leaf and root antioxidants. On the basis of these findings we will perform an in-depth analysis of the barley metabolome (B6) and transcriptome (B7) with two specific foci: First, to elucidate the process of establishment of the mutualistic fungus within the barley roots; second, to characterize elements of the systemic response in leaves leading to an interruption or failure of compatibility processes required for successful establishment of biotrophic leaf pathogens like Blumeria. New gene candidates will be pre-selected systematically for their regulatory role in compatibility by means of transiently transformed barley leaves upon Blumeria inoculation. Stable transgenic barley and maize lines (B3) generated with verified gene candidates and genes identified by other projects (A1, A2, B5, B6) will be tested with Blumeria and P. indica. By comparing candidate genes in the different plant - microbe systems, we will identify common regulatory processes, metabolites and metabolic networks implicated in compatibility including those required for successful interactions with mutualistic fungi.
This dataset contains geochemical variables measured in six depth profiles from ombrotrophic peatlands in North and Central Europe. Peat cores were taken during the spring and summer of 2022 from Amtsvenn (AV1), Germany; Drebbersches Moor (DM1), Germany; Fochteloër Veen (FV1), the Netherlands; Bagno Kusowo (KR1), Poland; Pichlmaier Moor (PI1), Austria and Pürgschachen Moor (PM1), Austria. The cores AV1, DM1 and KR1 were taken using a Wardenaar sampler (Royal Eijkelkamp, Giesbeek, the Netherlands) and had diameter of 10 cm. The cores FV1, PM1 and PI1 had an 8 cm diameter and were obtained using an Instorf sampler (Royal Eijkelkamp, Giesbeek, the Netherlands). The cores FV1, DM1 and KR1 were 100 cm, core AV1 was 95 cm, core PI1 was 85 cm and core PM1 was 200 cm. The cores were subsampeled in 1 cm (AV1, DM1, KR1, FV1) and 2 cm (PI1, PM1) sections. The subsamples were milled after freeze drying in a ballmill using tungen carbide accesoires. X-Ray Fluorescence (WD-XRF; ZSX Primus II, Rigaku, Tokyo, Japan) was used to determine Al (μg g-1), As (μg g-1), Ba (μg g-1), Br (μg g-1), Ca (g g-1), Cl (μg g-1), Cr (μg g-1), Cu (μg g-1), Fe (g g-1), K (g g-1), Mg (μg g-1), Mn (μg g-1), Na (μg g-1), P (μg g-1), Pb (μg g-1), Rb (μg g-1), S (μg g-1), Si (μg g-1), Sr (μg g-1), Ti (μg g-1) and Zn (μg g-1). These data were processed and calibrated using the iloekxrf package (Teickner & Knorr, 2024) in R. C, N and their stable isotopes were determined using an elemental analyser linked to an isotope ratio mass spectrometer (EA-3000, Eurovector, Pavia, Italy & Nu Horizon, Nu Instruments, Wrexham, UK). C and N were given in units g g-1 and stable isotopes were given as δ13C and δ15N for stable isotopes of C and N, respectively. Raw data C, N and stable isotope data were calibrated with certified standard and blank effects were corrected with the ilokeirms package (Teickner & Knorr, 2024). Using Fourier Transform Mid-Infrared Spectroscopy (FT-MIR) (Agilent Cary 670 FTIR spectromter, Agilent Technologies, Santa Clara, Ca, USA) humification indices (HI) were determined. Spectra were recorded from 600 cm-1 to 4000 cm-1 with a resolution of 2 cm-1 and baselines corrected with the ir package (Teickner, 2025) to estimate relative peack heights. The HI (no unit) for each sample was calculated by taking the ratio of intensities at 1630 cm-1 to the intensities at 1090 cm-1. Bulk densities (g cm-3) were estimated from FT-MIR data (Teickner et al., in preparation).

Von der so genannten Abwasserabgabe profitierte im Jahr 2025 und profitiert der Landkreis Stendal auch im Jahr 2026. Insgesamt flossen über 1 Mio. Euro der Abgabe in die Abwasserinfrastruktur des Kreises. Auch für das Jahr 2026 stehen Gelder in Höhe von rund 830.000 Euro für Abwassermaßnahmen in der Region bereit. Im Jahr 2025 verzeichnete das Landesverwaltungsamt Einnahmen aus der Abwasserabgabe in Höhe von 14 Mio. EUR (Stand 31.12.2025). Diese beruhen auf insgesamt ca. 1.800 Bewertungen von Abwassereinleitungen, in deren Ergebnis diese Umweltabgaben verhängt wurden. Im Jahr zuvor wurden 14,1 Mio. EUR eingefordert. Landesweit ist erfreulicherweise ein leichter Rückgang der Anzahl der Schmutzwassereinleitungen zu verzeichnen. „Wer Gewässer durch das Einleiten von Abwasser verschmutzt, muss dafür ein zweckgebundenes Ressourcennutzungsentgelt zahlen. Das ist die Wirkungsweise der so genannten Abwasserabgabe. Sie wurde im Jahre 1976 eingeführt, als erste Umweltabgabe überhaupt.“, erklärt der Präsident des Landesverwaltungsamtes Thomas Pleye. Für das Einleiten von Abwasser in ein Gewässer ist vom Verursacher eine Abgabe zu entrichten. Deren Höhe richtet sich nach der Höhe und Schädlichkeit der eingeleiteten Abwasserfracht. Die Abwasserabgabe sorgt dafür, dass für die Nutzung der Gewässer für das Beseitigen von Abwasser eine finanzielle Kompensation gezahlt werden muss. Sie soll den Vorteil abschöpfen, den die Inanspruchnahme dieses öffentlichen Guts für den Einleiter hat. Für die Festsetzung und Erhebung der Abwasserabgabe ist in Sachsen-Anhalt zentral das Landesverwaltungsamt zuständig. Das Aufkommen der Abwasserabgabe ist im Wesentlichen für den Gewässerschutz zu verwenden und wird so in die heimische Umwelt reinvestiert. Mit diesen Mitteln wurden im Jahr 2025 landesweit 16 Maßnahmen fertiggestellt, für die Fördermittel von ca. 11 Mio. Euro bereitgestellt wurden. Im Jahr 2025 wurden darüber hinaus 10 Maßnahmen mit Zuwendungen von rund 4,7 Mio. EUR aus dem Aufkommen der Abwasserabgabe neu bewilligt, die sich nun in der Umsetzung befinden. Hintergrund Gewässer durch das Einleiten von Abwasser nutzen zu dürfen: Dies hat einen Preis, einerlei, ob das Einleiten vermeidbar wäre oder nicht. Werden Überwachungswerte überschritten, handelt es sich um eine übermäßige Nutzung - dann ist der Preis entsprechend höher. Das aber kann der Einleiter in aller Regel vermeiden, indem er entsprechende Vorsorge trifft, um seine Anlagen unter allen zu erwartenden Betriebszuständen ordnungsgemäß betreiben zu können. Die Abwasserabgabe flankiert gewissermaßen die Gebote und Verbote des Wasserrechts. Die jährlichen Einnahmen in diesem Bereich schwanken daher naturgemäß. Investiert der Einleiter in seine Anlagen, um die Reinigungsleistung zu verbessern und um zusätzliche Einwohner anzuschließen, kann er solche Aufwendungen unter bestimmten Voraussetzungen mit seiner Abwasserabgabe verrechnen. Seit einigen Jahren betrifft das ungefähr die Hälfte der landesweit festgesetzten Abwasserabgabe; zuvor war der Anteil noch deutlich höher. Investitionen in den Anlagenbestand werden also prämiert. Die Abwasserabgabe setzt auch insoweit wirtschaftliche Impulse. Das Aufkommen der Abwasserabgabe steht für Maßnahmen des Gewässerschutzes zur Verfügung. In Sachsen-Anhalt sind so seit 1995 rund 250 Mio. EUR in die Abwasserinfrastruktur der kommunalen Aufgabenträger geflossen. Davon haben vor allem die Verbraucher als Gebührenzahler profitiert. Aber ebenso sind Maßnahmen zur Gewässerrenaturierung oder zur Verbesserung der Gewässergüte zu finanzieren. Gewässerschutz braucht Kontrollen und Förderung Kontrollen sind essenziell für den Gewässerschutz – sie umfassen technische Überwachung, Probenahmen, Genehmigungen und die Kontrolle geförderter Bauprojekte. Ungefähr 750 industrielle und gewerbliche Anlagen unterliegen in Sachsen-Anhalt den speziellen Vorschriften der Industrieemissionsrichtline der Europäischen Union. Dazu gehören beispielsweise Chemieanlagen, Tierhaltungsanlagen und Abfallbehandlungsanlagen. Oft sind dabei auch wasserrechtliche Tatbestände betroffen und müssen regelmäßig u.a. durch die Wasserwirtschaftsingenieure des Landesverwaltungsamtes kontrolliert werden. Bei kommunalen Abwassermaßnahmen, die vom Landesverwaltungsamt bezuschusst werden, wird der Baufortschritt überwacht und Auszahlungsanträge freigegeben. Allein 2025 hat das LVwA aus Mitteln des Europäischen Fonds für Regionale Entwicklung (EFRE) 28,9 Mio. Euro für 25 wasserwirtschaftliche Maßnahmen zur Verbesserung der Energieeffizienz bewilligt. Hinzu kamen weitere 10 Bewilligungen aus nationalen Mitteln für weitere wasserwirtschaftliche Maßnahmen mit einem Umfang von ca. 4,7 Mio. Euro. Die Zuschüsse sollen dazu beitragen, dass die kommunalen Anlagen auf einem sehr hohen technischen Stand und die Gebühren und Beiträge der Einwohner in einem verträglichen Rahmen bleiben.
