Ocean Acidification

Ocean Acidification

Ocean acidification is the change in pH of seawater due to the oceans absorbing carbon dioxide emissions to the atmosphere.


Why does ocean acidification happen?



  • Impacts on ocean life & ecosystems
    • Examples of impacted organisms
      • Invertebrates
        • Corals 
        • Pteropods
        • Oysters, Mussels, Clams
        • Urchins
      • Fish
      • Foraminifera
    • Examples of ecosystem scale responses
    • Interactions with other stressors (multistressor)
      • hypoxia
      • changes in salinity
