Ocean liming (OL) is a potential CDR method that aims to increase the ocean’s capacity to absorb atmospheric CO₂ by adding hydrated lime to the surface ocean. Modeling studies indicate that OL may cause temporary pH spikes lasting several minutes, depending on the lime sparging rate. Little is known about the short-term effects of these spikes on marine organisms. Aim of the present study is to investigate these effects on the copepod Acartia tonsa.
