Ocean Acidification Basics (Lesson 1)

Ocean acidification begins with 

• pollution from ships

• carbon dioxide released from combustion

• dumping of waste from cities into the ocean

• toxic chemicals being released into the air

This image demonstrates that

• There is a direct correlation with the atmospheric CO₂ and the CO₂ in seawater

• That pH of the ocean increases as the atmospheric CO₂ increases

• That there is no correlation between pH of the ocean and atmospheric CO₂
