Abstract:

We describe year-long experiments in which back reef and fore reef (17-m depth) communities from Moorea, French Polynesia, were incubated outdoors under pCO2 regimes reflecting endpoints of representative concentration pathways (RCPs) expected by the end the century. Incubations were completed in 3–4 flumes (5.0 × 0.3 m, 500 L) in which seawater was refreshed and circulated at 0.1 m s-1, and the response of the communities was evaluated monthly by measurements of net community calcification (NCC) and net community photosynthesis (NCP).

Comment:

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 2024-03-04.
