CO2SYS is a family of software programs that calculate chemical equilibria for aquatic inorganic carbon species and parameters. Their core function is to use any two of the four central inorganic carbon system parameters (pH, alkalinity, dissolved inorganic carbon, and partial pressure of carbon dioxide) to calculate various chemical properties of the system. These programs are widely used by oceanographers and limnologists to understand and predict chemical equilibria in natural waters.[1]
