NERC EDS Environmental Information Data Centre 10.5285/20837a27-414c-4597-a6d2-3edc1d2e9a98 These data encompass land cover data and sediment geochemistry from the Rio Santa catchment of the Peruvian Andes. Sediment samples were collected within the SIGMA: Peru project between 2019-2020. Geochemistry data include major and minor elements in sediment samples determined by X-Ray Fluorescence (XRF), organic matter determined by loss-on-ignition (LOI), and particle size data, and are provided for both the wider Rio Santa catchment and the Ranrahirca sub-catchment. The research was supported by the Natural Environment Research Council and the Newton Fund (grant NE/S013245/1).

Sediment samples were collected in the field between 2019 and 2020 to characterise the range of sediment sources contributing to channel sediments in the Rio Santa catchment and Ranrahirca sub-catchment. Samples were oven dried, sieved to <63 μm, and prepared as required for further analyses. Data were produced on organic content (via loss-on-ignition), particle size (via laser diffraction) and major and minor elements (via Wavelength Dispersive X-Ray Fluorescence). All data were assessed for quality and erroneous values removed.
