Could artificial ocean alkalinization protect tropical coral ecosystems from ocean acidification?
Artificial ocean alkalinization (AOA) is investigated as a method to mitigate local ocean acidification and protect tropical coral ecosystems during a 21st century high CO _2 emission scenario. Employing an Earth system model of intermediate complexity, our implementation of AOA in the Great Barrier...

Artificial ocean alkalinization (AOA) is investigated as a method to mitigate local ocean acidification and protect tropical coral ecosystems during a 21st century high CO _2 emission scenario.

Beyond preventing local acidification, regional AOA, however, results in locally elevated aragonite oversaturation and pCO _2 decline. A notable consequence of stopping regional AOA is a rapid shift back to the acidified conditions of the target regions.
