  • 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
