Presentation Transcript

  1. Recent interests • Discovery of hydrothermal vent • The link between global warming & ocean: the Carbon story • Microbial loop • Industrialized mariculture: Peter Drucker

  2. The Carbon Story • Global warming: carbon dioxide • Ocean: an ideal carbon sink • Some oceans are iron limiting: Southern Ocean • Hypothesis: Fertilization with Fe increases carbon sink

  3. fertilizing the oceans with iron

  4. Sea change: a satellite image of a 200-km algal bloom (orange) caused by iron fertilization

  5. Southern Ocean Iron Fertilization Experiment (SOFeX) • Iron sulfate Solution on the sea surface • 200 km phytoplankton bloom • Carbon can be transported below 100 metres by iron fertilization • Fe : C = 1 : 1000 • Lab experiment predicted 1 : 100,000
