Its uptake increases seawater acidity and lowers the saturation state of waters with respect to calcite (ΩC) and aragonite (ΩA), the two most common CaCO3 polymorphs that constitute the shells and skeletons of many marine organisms. Ocean acidification can have deleterious effects on carbonate-secreting organisms (e.g. mollusks and crustaceans) and certain physiological processes in non-calcifying organisms.\n\nAs part of the *eDrivers* project, we used ΩA to characterize ocean acidification in the bottom waters of the St. Lawrence. The data come from the Department of Fisheries and Oceans’ (DFO) Atlantic Zone Monitoring Program surveys and DFO’s multispecies surveys collected in August-September of 2017. ΩA, pH, and dissolved oxygen (O2) were measured at 117 stations in the Estuary and Gulf of St. Lawrence in the summer of 2018. The majority of sampling stations were located in the Southern Gulf (n = 84), the Estuary and Northern Gulf (n = 33).\n\nIt is possible to consult the scientific report of the **eDrivers** project: [Characterizing Exposure to and Sharing Knowledge of Drivers of Environmental Change in the St. Lawrence System in Canada](https://www.frontiersin.org/articles/10.3389/fmars.2020.00383/full) and the [additional data](https://www.frontiersin.org/articles/10.3389/fmars.2020.00383/full#supplementary-material).

Son absorption augmente l'acidité de l'eau de mer et abaisse l'état de saturation des eaux par rapport à la calcite (ΩC) et à l'aragonite (ΩA), les deux polymorphes de CaCO3 les plus courants qui constituent les coquilles et les squelettes de nombreux organismes marins. L'acidification des océans peut avoir des effets délétères sur les organismes sécrétant des carbonates (par exemple les mollusques et les crustacés) et sur certains processus physiologiques chez les organismes non calcifiants.\n\nDans le cadre du projet ***eDrivers***, nous avons utilisé ΩA pour caractériser l'acidification des océans dans les eaux de fond du Saint-Laurent. Les données proviennent des relevés du programme de surveillance de la zone Atlantique du ministère des Pêches et des Océans du Canada (MPO) et des relevés multispécifiques du MPO collectés en août-septembre 2017. Le ΩA, le pH et l'oxygène dissous (O2) ont été mesurés dans 117 stations de l'estuaire et du golfe du Saint-Laurent au cours de l'été 2018.
