carbonate saturation state
Carbonate saturation state refers to the balance of carbonate ions (CO3^2-) in water, particularly in oceans. It indicates how much carbonate is available for marine organisms, like corals and shellfish, to build their shells and skeletons. A saturation state above 1 means there's enough carbonate for these organisms to thrive, while a state below 1 means they may struggle. Factors like ocean acidification, caused by increased carbon dioxide in the atmosphere, can lower this saturation, threatening marine ecosystems and biodiversity. Understanding this helps us gauge ocean health and its impact on marine life.

Carbonate saturation state refers to the concentration of carbonate ions in water compared to the levels needed for carbonate minerals, like calcium carbonate, to form or dissolve. It's essential for marine life, particularly organisms like corals and shellfish that rely on these minerals to build their shells and skeletons. When the saturation state is high, conditions favor mineral formation; when it's low, minerals may dissolve, which can harm marine ecosystems. Changes in ocean chemistry, often caused by factors like climate change and ocean acidification, can impact the carbonate saturation state and, consequently, marine life.
