We evaluated the recovery capacity of a model calcifier, the Pacific oyster Crassostrea gigas. We exposed juveniles to 15 pH conditions between 6.4 and 7.8 for 14 days. Oyster growth was retarded below pH 7.1 while shells were corroded at pH 6.5. We then placed the oysters under ambient pH > 7.8 for 42 days. The oysters from each pH condition were briefly dried with absorbent paper and the total wet body weight was measured with a Mettler precision balance (Mettler-Toledo) during the exposure period on days 6, 10 and 14, and then during the ambient pH period on days 4, 7, 9, 11, 14, 18, 22, 28, 36 and 42. ... : In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2022) 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 2023-09-06. ...
