CO2SYS/Evidence
Method evidence record

CO2SYS

CO2SYS is a widely-used software package for calculating the speciation and equilibrium state of the marine carbonate system from measurements of two carbonate parameters. Developed by Ernie Lewis and Doug Wallace in 1998, CO2SYS enables oceanographers to compute all carbonate species (dissolved CO2, bicarbonate, carbonate), saturation states, and pH from pairs of measured parameters. The tool is essential for ocean acidification monitoring and research.
