In this paper, we introduce the largest and most comprehensive database for riverine particulate organic carbon carried by suspended particulate matter in Earth's fluvial systems: 3546 data entries for suspended particulate matter with detailed geochemical parameters are included, and special attention goes to the elemental and isotopic carbon compositions to better understand riverine particulate organic carbon and its role in the carbon cycle from regional to global scales.

Silicon (Si) is essential for ecosystem health and Earth's climate, yet human activities such as agriculture have significantly disrupted its natural cycle. In a French agricultural catchment, we found that crop harvesting removes most of the Si released from rocks—1 to 4 times more than the dissolved Si transport downstream by rivers. Using geochemical tools, including Si isotopes and germanium-silicon ratio, we traced Si cycling and highlighted the impact of agriculture on Si exports.

This study describes a unique large-scale isotope dataset to study water dynamics in European forests. Researchers collected data from 40 beech and spruce forest sites in spring and summer 2023, using a standardized method to ensure consistency. The results show that water sources for trees change between seasons and vary by tree species. This large dataset offers valuable information for understanding plant water use, improving ecohydrological models, and mapping water cycles across Europe.

Short summary
The proposed methodology consists of simultaneously analysing the concentration variation of solute pairs during a storm event by plotting the concentration variation of one solute against the variation of another solute. This can reveal whether two or more end-members contribute to streamflow during a storm event. Furthermore, the variation of the solute ratios during the events can indicate which catchment processes are dominant and which are negligible.

X-ray absorption spectroscopy (XAS) was successfully used to investigate the atomic-scale environment of niobium (Nb) in ore minerals and Nb-doped compounds of technological importance. The demonstrated sensitivity of this technique to Nb minerals could help decipher Nb speciation in mining contexts such as hydrothermal and lateritic deposits and rationalize the origin of the enhanced physico-chemical properties of Nb-doped materials.

As a result of the collision between the European and Apulian plates, the Alps have experienced several evolutionary stages. The Penninic frontal thrust (PFT) (major thrust) was associated with compression, and now seismic studies show ongoing extensional activity. Calcite mineralization associated with shortening and extensional structures was sampled. The last deformation stages are dated by U–Pb on calcite at ~ 3.5 and ~ 2.5 Ma. Isotope analysis evidences deep crustal fluid mobilization.

The abundance and isotope composition of the trace metal barium (Ba) allows us to track and quantify nutrient cycling throughout the Amazon Basin. In particular, we show that the Ba biological fingerprint evolves from that of a strong net nutrient uptake in the mountainous area of the Andes towards efficient nutrient recycling on the plains of the Lower Amazon. Our study highlights the fact that the geochemical signature of rock-derived nutrients transported by the Amazon is scarred by life.

Short summary
Through a river cross-section, we show that fluvial organic carbon in the lower Huanghe has clear vertical and lateral heterogeneity in elemental and isotopic signals. Bank erosion supplies terrestrial organic carbon to the fluvial transport. Physical erosion of aged and refractory organic carbon, including radiocarbon-dead organic carbon source from the biosphere, from relatively deep soil horizons of the Chinese Loess Plateau contributes to fluvial particulate organic carbon in the Huanghe.
Through a river cross-section, we show that fluvial organic carbon in the lower Huanghe has...
