Data to investigate measurement of nutrients in saline and hypersaline waters by discrete analyzer colorimetry without matrix matched calibration standards

The dataset consists of two spreadsheets of data for water samples of varying salinity. One spreadsheet contains measured concentrations of nutrients in filtered water samples that were corrected for salinity effects when necessary, and measured concentrations of nutrients spiked into environmental samples or blank water that were corrected for salinity effects when necessary. The second spreadsheet contains measured concentrations of ammonia and silica in filtered water samples without the salinity correction applied, and measured concentrations of ammonia and silica spiked into environmental samples or blank water without the salinity correction applied.
