Comment:
Missing values correspond to concentrations below detection. DIC not measured for May 2012 samples, so charge imbalance error (CIB) not calculated. Salinity calculated from specific conductivity (SpC) using calculator at http://www.chemiasoft.com/chemd/salinity_calculator, after Standard Methods for the Examination of Water and Wastewater, 20th edition, 1999.
