To test the effect of electrochemically induced alkalinity enhancement (eAE) on coral propagation, we used pH microsensors and incubations to measure eAE-altered carbonate chemistry. We then conducted two coral growth experiments, one with Acropora cervicornis and one with two heights of Pseudodiploria clivosa.This dataset is included in the OA-ICC data compilation maintained in the framework of the IAEA Ocean Acidification International Coordination Centre (see https://oa-icc.ipsl.fr). Original data were downloaded from github (see Source) by the OA-ICC data curator. In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2024) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation by seacarb is 2026-04-08.
