Document Summary

Carbonated drinks: pressurized co2 is dissolved in water. When opened at normal pressure, it releases co2 bubbles. Higher atmospheric co2 means more co2 dissolves in seawater. When co2 is dissolved in water, some carbonic acid is formed (h2co3) And the ph of the ocean has been decreasing as co2 levels have risen. Observed drop in ph corresponds to 30% more hydrogen ions. Tums: has calcium carbonate (what marine organisms use to build sh. Creatures with shells also reach with acid (phytoplankton: responsible for. High latitudes will have surface water below the saturation threshold (<1 = Tropics will still be above, but nearing the threshold. Increasing the acidity of the ocean has a negative impact on many types of biolo. Larvae are particularly sensitive, and some organisms make calcium carbo. Ocean ph might make mussels less able to hold onto rocks. Puget sound waters are particularly acidic ph = 7. 8 compare to 8. 1 on a global average.
