The Sensitivity of the Marine Carbonate System to Regional Ocean Alkalinity Enhancement [PDF]
Frontiers in Climate, 2021 Ocean Alkalinity Enhancement (OAE) simultaneously mitigates atmospheric concentrations of CO2 and ocean acidification; however, no previous studies have investigated the response of the non-linear marine carbonate system sensitivity to alkalinity ...
