Seawater carbonate chemistry and coral reef community metabolism

Using fumes (5.0×0.3×0.3 m) located outdoors in Moorea, French Polynesia, we assembled local back reef communities with ~25% coral cover, and tested their response to pCO2 levels of 344, 633, 870 and 1146 μatm. Incubations began in late Austral spring (November 2015), and net community calcifcation (Gnet) and net community primary production (Pnet) were measured prior to treatments, 24 h after treatment began, and biweekly or monthly thereafter until early Austral autumn (March 2016). 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 BCO-DMO (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 2024-11-12.
