This dataset is a supplementary dataset to the manuscript: “Uhlig, D., Schuessler, J. A., Bouchez, J. L., Dixon, J., and von Blanckenburg, F.: Quantifying nutrient uptake as driver of rock weathering in forest ecosystems by magnesium stable isotopes, Biogeosciences, 2017“. The dataset contains physicochemical parameters of stream water (pH, temperature, conductivity discharge, alkalinity) , and chemical and Mg isotope analyses of stream water, vegetation, soil, saprolite, weathered bedrock and unweathered bedrock of three headwater catchments at Providence Creek in the Southern Sierra Nevada, California, USA. Further, the dataset contains soil and saprolite weathering indicators such as the chemical depletion fraction (CDF) and mass transfer coefficients, as well as elemental regolith production fluxes, elemental net solubilisation fluxes, elemental dissolved river fluxes, elemental litterfall fluxes, nutrient recycling fluxes and elemental dissolved export efficiencies that rely on measured data reported in the above study and data from literature. These data and metrics were used to track the pathway of Mg and other nutrients through the headwater catchments at the Critical Zone Observatory of the Southern Sierra Nevada....
