Seawater carbonation

Seawater carbonation is a natural or engineered process where carbon dioxide (CO₂) gas dissolves into seawater, reacting with minerals like calcium and magnesium to form stable compounds such as calcium carbonate. This process helps regulate atmospheric CO₂ levels and can contribute to reducing greenhouse gases. It occurs naturally when CO₂ from the atmosphere dissolves in ocean water or can be enhanced artificially to store carbon dioxide safely in the ocean, mitigating climate change. Seawater carbonation plays a role in both the Earth's carbon cycle and efforts to develop sustainable carbon management strategies.
