From: Ocean acidification modulates material flux linked with coral calcification and photosynthesis

Conceptual model of final proposed hypotheses for significantly increased oxygen (O2) efflux in light conditions, decreased proton efflux in dark conditions, no significant difference (n.s.) in the surface of the coral—change (Δ) pH total (pHT), and a significant (sig.) difference the surface Δ oxygen (O2) concentrations under ↑pCO2 = ocean acidification. Arrow thickness is represents the magnitude of flux.
