BetaBetaDataset
To assess the chemistry of three karst sites in China.
The pH sonde was calibrated every month by trained operators following standard operating procedures. For nitrate-N sensor calibration, discrete stream water samples for validation were collected manually at weekly or biweekly intervals, with additional samples collected during precipitation event periods using autosamplers at sampling intervals of one to four hours.
Dataset entails temperature, specific conductivity, pH, dissolved oxygen and nitrate.
Nitrate-N sensor and laboratory analysis. Three karst springs were investigated. Data were obtained via sensor approach with a 15-minute time interval between May 2016 to October 2017.
