Is the PH of ocean water constant?



  1. 0 Votes

    According to a recent study, not only does the pH of sea water fluctuate significantly, but the overall pH has been dropping as CO2 levels in the atmosphere have risen. The study also found that a region’s pH can change .24 units in any 24-hour period, and 1.5 units over the course of a year. Factors affecting the pH of ocean water are available sunlight, water temperature, and amount of phytoplankton, in addition to atmospheric CO2 levels.
