  • Solubility and kinetic data for Fe(II)-silicate precipitation over a range of temperatures, as well as metal drawdown and metal release during diagenesis. Characterisation data for solid precipitates using FTIR and XRD. The XRDML data should be opened on Panalytical highscore, and the XLS file should be opened with Excel, Numbers or OpenOffice.

  • This dataset contains RGB photographs acquired from drone surveys. There are 741 harvest plots from 38 surveys at 36 sites around the world. Each site was approximately 1 ha in area. Included with the photographic images are the coordinates of ground control markers, biomass, taxonomic and location data for harvest plots and ancillary metadata. The observations can be used to obtain allometric size-biomass models. This work was supported by the Natural Environment Research Council award number NE/R00062X/1 as part of the project 'Do dryland ecosystems control variability and recent trends in the land CO2 sink?'
