A diagram showing how increased CO2 leads to more acidic water resulting in a reduction in carbonate.Ocean acidification is a current and future problem for the ocean. The average coastal ocean pH is 8.2 in southern California, but it is changing because of the addition of carbon dioxide to the atmosphere and the subsequent absorption of that carbon dioxide into the ocean. Students in this lesson will learn how CO2 is being absorbed into water.
