  1. Human Impact on the Oceans Presented by: Courtney Martinez

  2. Topics Covered: • Acidification • Dead Zones • Over Fishing • The Garbage Patch

  3. Acidification “OA” for short, is the term given to the chemical changes in the ocean as a result of carbon dioxide emissions

  4. Acidification Hawaii Carbon Dioxide Time-Series Location of planned OA monitoring and research sites and affiliated NOAA labs

  5. Acidification How the oceans absorb carbon dioxide is critical for predicting climate change

  6. Acidification Figure showing the change in carbon chemistry relative to preindustrial carbon dioxide

  7. Acidification How the oceans store CO2 is critical for understanding the global carbon cycle

  8. Acidification CO2 uptake is not the same as carbon storage. Anthropogenic CO2 absorbed in one region may be moved by ocean circulation and ultimately stored in a different region. Map of the column inventory of anthropogenic CO2 in 1994 (Sabine et al., 2004)

  9. Acidification In 2008, Oyster harvest plummets 80% The Road to Remedy? The IOOS Buoy

  10. Topics Covered: • Acidification • Dead Zones • Over Fishing • The Garbage Patch

  11. Dead Zones What causes a dead zone? Where are they located?

  12. Topics Covered: • Acidification • Dead Zones • Over Fishing • The Garbage Patch

  13. Over Fishing Fleets = 2-3 Times bigger than necessary 52% of Fish stocks are “fully exploited”

  14. Topics Covered: • Acidification • Dead Zones • Over Fishing • The Garbage Patch

  15. The Garbage Patch What is it made of?

  16. The Garbage Patch How is it formed? What’s the problem?
