P.2. Local Influences on Ocean Acidification

Acid Rain

Acid Rain

  • Effect: Acid rain, with a pH between 1 and 6, impacts the chemistry of surface ocean waters.
  • Extent: Major effects on ocean acidification are seen locally and regionally but have a relatively small global impact.

Eutrophication

  • Cause: Coastal waters are influenced by excess nutrients, mainly nitrogen, from sources like agriculture, fertilizers, and sewage.
  • Result: This leads to eutrophication, causing significant plankton blooms. When these blooms collapse and sink, bacteria decompose them, reducing seawater oxygen and increasing CO2 (lowering pH).

Reactions in Ocean Acidification

    1. Processes: The term ‘ocean acidification’ summarizes reactions between CO2 and seawater.
  • Key Reactions:
  • Formation of Carbonic Acid:
        1. Reaction: CO2 + H2O → H2CO3 → H+ + HCO3-
        2. Effect: This releases hydrogen ions, increasing acidity and lowering pH.
  • Interaction between Carbonate Ions, CO2, and Water:
    1. Reaction: CO3^2- + CO2 + H2O → 2HCO3-
    2. Combined Effect: Increases acidity and reduces the availability of carbonate ions.
