Correlation of atmospheric CO2, ocean CO2, and change in seawater pH

Correlation of atmospheric CO2, ocean CO2, and change in seawater pH

Caption: This graph shows the correlation between rising levels of carbon dioxide (CO2) in the atmosphere at Mauna Loa with rising CO2 levels in the nearby ocean at Station Aloha. As more CO2 accumulates in the ocean, the pH of the ocean decreases. (Modified after R.A.
