FEATURED TOPIC

What is Ocean Acidification?

Absorption of carbon dioxide by the ocean is altering ocean chemistry. Carbon dioxide is an acid gas-- when it dissolves in water it forms carbonic acid, which effectively makes the water more acidic. Although ocean water is naturally basic (pH > 7) the process of absorbing carbon dioxide decreases the pH, which means it is becoming more acidic.
