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
