Coral reef metabolism and carbon chemistry dynamics of a coral reef flat

摘要: Global carbon emissions continue to acidify the oceans, motivating growing concern for ability of coral reefs maintain net positive calcification rates. Efforts develop robust relationships between reef and carbonate parameters such as aragonite saturation state (Ωarag) aim facilitate meaningful predictions how will change in face ocean acidification. Here we investigate natural trends chemistry a flat over diel cycles relate these benthic fluxes by quantifying community production. We find that, despite an apparent dependence on Ωarag seen simple pairwise relationship, if photosynthesis is accounted for, knowing does not add substantial explanatory value. This suggests short time scales, control weak relative factors governing photosynthesis.
