Oceans becoming more acidic

  1. Jul 29, 2006 #1
    Higher concentrations of CO2 in the atmosphere means higher concentrations in the oceans. This means the oceans become more acidic. It is predicted that the PH will change from 8.1 currently, to 7.7 in 100 years.

    This can have catastrophic effects on ocean flora and fauna. Whether or not one believes in AGW, the pollution and other side effects of burning fossil fuels should be reason enough to take action to curb the use of fossil fuels.

    Sounds bad, but I don't know anything about it. I have no idea what the scale is for the increase in CO2 ppm.

    What is unprecedented here is not the higher concentration of CO2 in the atmosphere. It is the rate of increase that is alarming. The oceans and the life in them do not have the generations normally associated with such changes to adapt and adjust.

    This document details the ocean acidification process in great detail.

    It is not necessarily just the pH, which varies in the oceans from 8.2 - 7.8 depending on regional and seasonal variations. There is also the concentrations of CO3. Explained more fully here.

    Increase in surface CO2 concentration is also consistent with the consequences of overfishing --- the microbiota is not compacted into fecal pellets that settle rapidly into deep water, and remains in a "short-circuited" surface carbon cycle. Normal ocean turnover over a century brings 300 m or so of deep, pH ~ 7.5, water to the surface.
