This dataset includes measured physicochemical variables in ten rivers of the glacial valleys of Parón, Huaytapallana and Llanganuco in the Cordillera Blanca, Ancash, Peru. The environmental variables measured in the rivers include pH, turbidity conductivity, total nitrogen, total phosphorus, dissolved organic carbon, dissolved inorganic carbon, metal ions and anions. Channel stability assessments using the Pfankuch index are also included.

This data was used to analyse the physicochemical changes under glacial retreat, studying rivers in a gradient of glacial coverage, and relate it to the biodiversity of macroinvertebrates.

The sampling work was carried out from October 14 to 30, 2019 and from October 7 to 16, 2020.

The study was funded by NERC, Newton‐Paulet Fund and Fondo Nacional de Desarrollo Científico, Tecnológico y de Innovación Tecnológica-Perú.

Provenance & quality

Field environmental parameters were measured with the previously calibrated Multi 3630 IDS multiparametric instrument. Water samples were collected for analysis of metal ions, anions and nutrients in the laboratory of the Faculty of Environment, University of Leeds, England. Calibration standards with known concentrations were used to ensure the accuracy and precision of the measurements. More detail is available in the supporting documentation accompanying the data.
