@agu.org New in #JGR a study on 🌊 Ocean Alkalinity Enhancement: higher alkalinity speeds up growth of key #coccolithophores, but at very high TA calcification falters & shells deform. Authors suggest TA <~3,000 μmol kg−1 as a safer ecosystem boundary. doi.org/10.1029/2025... #protistsonsky

The Physiological Response of Contrasting Coccolithophore Species to Ocean Alkalinity Enhancement
Increased alkalinity significantly boosts growth rates of coccolithophores Gephyrocapsa huxleyi and Coccolithus braarudii
Divergent responses between species arise as large C. braarudii rely on C...
