[ACG50-05] Minerals in Coastal Ocean: Recovery of Biomass-stocking Coral Reefs
Keywords:Mineral, Coastal Ocean, Coral Reefs, Recovery Potential, Biomass
Atmospheric carbon dioxide-dissolving surface seawater dissolves minerals and biomass. Reversible chemical reaction mechanism of acid/base dissociation reaction is essential in growth of individual marine calcifying organisms and in development to their colony. Reversible calcification reaction, Ca2+ + HCO3- = CaCO3 + H+, was by accident discovered via acid/base titration measurements at 2007 year. In surface seawaters calcification/decalcification reaction corresponds to acid dissociation reaction as above mentioned but in fresh water it means precipitation/dissolution of physical reaction Ca2+ + CO32- = CaCO3.
The nature of surface seawater is controlled into weak bases as proton concentration homeostasis. Seawater acidification due to absorption of anthropogenic carbon dioxide from atmosphere leads to mineral dissolution. For a study on net calcification rate the pH-dependent evaluation of [Ca2+] is essential by the standpoint of soluble carbonate chemistry. The sources of calcium ion concentration are expected from the leaching of minerals and biomass into coastal ocean or surface seawater. Biodiversity maintenance may be critical for coral reefs.
