Adding carbon dioxide (CO2) to seawater raises ,the acidity, of seawater, which can adversely affect marine life and fisheries. Coastal waters receive both atmospheric CO2 and CO2 from water pollution, and their combination can disproportionately accelerate acidification. This interaction is highly dependent on salinity and temperature. We created a model that evaluates all of these
