  •  Hmmm, interesting.... (1+ / 0-)

    Well, I guess I'm confused then; wouldn't we rather have carbon bound up in the form of calcium carbonate shells than in the atmosphere as carbon dioxide or dissolved into seawater and forming carbolic acid (and dissolving calcium carbonate shells)?

    •  I mean shells mostly w/ living shellfish in them, (0+ / 0-)

      not some ocean-wide CaCO3-fixing chemical experiment.

      My concern is that oceanic acidification will liberate new (i.e., currently sequestered) carbon from shells and coral reefs and thereby exacerbate (add feedback to) our current carbon overload.  

      I want to leave the shells/reefs intact by lowering acidification by reducing carbolic acid formation by reducing CO2 emissions by reducing the use of fossil (carbon) fuels by increasing building/process/vehicle efficiencies.

        with you ending sentiment bartco.  One thing we do know is that as atmospheric CO2 rises the problem of acidification becomes worse. It would be wise of us to reduce emissions.  Again, the dissolution of calclium carbonate shells or reefs actually buffers or helps to mitigate atmospheric CO2 increases and ocean acidification, not acerbate the problem.  CaCO3(s) dissolution contributes alkalinity to seawater which counteracts pH is counter intuitive but that is the way the chemistry works.
