Ocean Alkalinity Enhancement is a promising negative emissions technology with high CO2 capture potential, put forward to meet the 2015 Paris Agreement targets. However, most current knowledge relies on numerical models. This dataset present the first laboratory experiments focusing on quick and hydrated lime dissolution in natural seawater, for Ocean Alkalinity Enhancement purposes. The total alkalinity and dissolved inorganic carbon concentration were collected after various alkalinity increases, using different alkaline minerals. The total alkalinity was obtained by potentiometric titration, and the dissolved inorganic carbon concentration was measured with an automated infra-red inorganic carbon analyser, coupled to a LICOR infra-red detector.
