Quantifying the biogeochemical processes controlling seasonal acidification in the North Yellow Sea

Why is it important?
The NYS cold water mass net calcification rate declines to nearly zero when Ωarag reaches a critical level of 1.5 − 1.6. Using a future scenario to predict the impacts of rising atmospheric CO2 levels on seasonal variations of Ωarag and pH values, we show that very low Ωarag values of < 1.5 may exist all year round in the NYS subsurface waters by the 2050 s, while aragonite undersaturated water (Ωarag <1) may appear in autumn months, causing great stress to its benthic faunal community.
Perspectives
The metabolism-enhanced seawater acidification capable of threatening the Yellow Sea ecosystems could develop within decades rather than centuries.
