Can seagrass help fight ocean acidification? — Ocean acidification

Of course, the only way to truly fight ocean acidification reducing emissions Seagrass meadows could play a limited, localized role in alleviating ocean acidification in coastal ecosystems, according to new work led by Carnegie’s David Koweek and including Carnegie’s Ken Caldeira and published in Ecological Applications.When coal, oil, or gas is burned, the resulting carbon […]

  1. When a solution is referenced to a neutral 7.0 pH – values above are alkaline and become more or less alkaline, values below are acidic and become more or less acidic.

    The ocean’s pH is about 8.1. That’s alkaline. Variations are more or less alkaline, not more or less acidic. The obvious reason for incorrectly using the term “ocean acidification” is a propaganda gambit to scare the gullible and uninformed who associate acid with bad, like alien blood and spit.

    Highly alkaline compounds such as caustic soda can be just as dangerous as acidic compounds, e.g. concentrated bleach, sodium hypochlorite, pH 9 to 13. On the other hand: rain has a pH of 4.5, lemon juice has a pH of 2.0, tomatoes a pH of 4.5, and vinegar a pH of 2.2. If they get on your hands the flesh doesn’t melt and they don’t burn a hole in the kitchen counter. (Might etch that granite, though.)

    A solution goes from pH 0.0, dangerous acidity, to pH 7.0, neutral/safe, to pH 14.0, dangerous alkalinity. pH is chemical shorthand for the negative logarithm of H+ ion concentration.

    pH = -log[H+] (1)

    A pH of 9 represents 10^-9 or 1 part per billion H+ ions. A change from pH 8.2 (6.31 ppb M/l) to pH 8.1 (7.49 ppb M/l) is a -26% change (-1.18 ppb M/l) in the direction of lower alkalinity, not more acidity. Every whole number change is power of 10, a factor of 10. In a change in pH from 9 to 8 the H+ concentration increases by a power/factor of 10 or 1,000%!!!!!!! Makes the 26% look pretty trivial – which anything in ppb is.

    Applying percentages to a logarithmic scale/function is very dicey, but that’s what you get when food and life style editors write science articles.

    So, pH 8.1 is moving a YUGE 1 ppb in the direction of slightly more neutrality from pH 8.2 which is not much to begin with.

    Improperly using the term ocean “acidification” to scare the public over bogus CAGW is a disgrace to science. Spit out the Kool-Aid and grow a backbone.
