Exploring the Impact of Iron Fertilization on Ocean Carbon Storage and Global Warming

This exploration delves into the intriguing dynamics of oceanic carbon sequestration through iron fertilization. We investigate the relationship between global warming and oceanic processes, focusing on the microbial loop and hydrothermal vents. Highlighting experiments like SOFeX, we analyze how iron limits productivity in certain oceans, particularly the Southern Ocean, and the subsequent effects on carbon dioxide levels. Our findings reveal potential strategies for enhancing ocean's capacity as a carbon sink, aiming for better climate change mitigation.

  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
