Ocean acidification: the process, the future, and the past Ocean acidification: the process, the future, and the past Presentation Transcript

  • Ocean Acidification: the Process, the Future, and the Past Mieke Vrijmoet Communicating Science to the Public Nov 5 2013
  • The Mechanism Image courtesy NOAA, Monteray Bay National Marine Sanctuary
  • - Why does a change in CO3 matter? Image courtesy US EPA
  • Coral Reefs and Ocean Acidification Image courtesy Wikimedia Commons
  • Will this happen everywhere? Image courtesy Wikimedia commons with data via GODAP and Global Oceans Atlas
  • Paired with global warming…. ● Changes to range, community composition, and increased stress ● Possibility of coral bleaching
  • So what does it mean for the future?
  • Wait… this has happened before? Sharp decrease in calcium carbonate shows major decrease in calcifying organisms Source: Zachos, Science, 2005
  • how do we know that?
  • Can we stop it?
  • Our future remains to be seen!
