Ocean Acidification

Definition

Ocean acidification occurs when carbon dioxide (CO2) from sources like burning fossil fuels dissolves into seawater and lowers its pH level. This decrease in pH makes seawater more acidic over time, harming marine life such as coral reefs and shellfish.

Coral Bleaching:

Coral bleaching happens when corals expel their symbiotic algae due to stressors like high water temperatures or increased acidity. This causes them to turn white and can lead to their death.

Carbonic Acid:

Carbonic acid forms when carbon dioxide dissolves in water. It contributes to ocean acidification by lowering the pH of seawater.

Shell Dissolution: Shell dissolution occurs when acidic water corrodes or dissolves the shells of marine organisms like mollusks and crustaceans, making it difficult for them to survive.
