Abstract

This resource provides accompanying discharge and hydrologic data (silicon, sodium, calcium, magnesium, aluminum, germanium, discharge and irrigation fluxes) presented in 'Maturation of Silicate Weathering Pathways Revealed by Germanium-Silicon Ratios', Geophysical Research Letters, DOI: https://doi.org/10.1029/2025GL118410
This dataset combines measurements from two experiments conducted at the Landscape Evolution Observatory (LEO) in Tucson, Arizona from 2018-2019 and 2022-2023. Discharge chemistry and flux are reported for each of the three LEO hillslopes.

Files are provided in ".csv" format.
