Coral Reefs and Ocean Acidification

Understanding Ocean AcidificatioN

Ocean acidification is caused by the chemical reaction of carbon dioxide with seawater, leading to an increase in hydrogen ions and a decrease in carbonate ions. This decrease in carbonate ions makes it more challenging for marine organisms, like corals, to build and maintain their calcium carbonate skeletons or structures.

Impact on Coral Reefs:

• Bleaching and Loss of Biodiversity

Coral bleaching occurs when coral expel the symbiotic algae living in their tissues due to stress. Ocean acidification exacerbates this stress, making coral reefs more susceptible to bleaching events, which can result in the loss of vibrant colors and the death of corals. This decline in coral health directly affects the biodiversity and productivity of the entire reef ecosystem.

• Weakened Reefs and Erosion

As the acidity of the ocean increases, corals find it challenging to build and repair their skeletal structures. This process weakens the reefs, making them more susceptible to erosion from wave action and storms. The loss of coral reefs not only reduces vital habitat for fish and other marine species, but it also compromises the natural barriers that protect coastal communities from the impacts of severe weather events.

• Disrupted Food Chains:

Coral reefs support complex food webs, with coral acting as the foundation for diverse marine life. The decline of coral reefs due to ocean acidification disrupts these intricate ecosystems, leading to ripple effects throughout the food chain. As coral structures erode and corals struggle to regenerate, the entire community of organisms that depends on the reef for food and shelter faces a significant loss.

Mitigating Ocean Acidification and Preserving Coral Reefs

Reducing Carbon Emissions

Addressing the root cause of ocean acidification requires a concerted effort to reduce carbon emissions. Transitioning to cleaner and renewable sources of energy and promoting sustainable practices can significantly contribute to mitigating this threat.
