Working Group 22: Iron supply and its impact on biogeochemistry and ecosystems in the North Pacific Ocean
  • Acronym: WG 22
  • Parent Committee: BIO
  • Term: Oct. 2007 - Oct. 2010
  • Co-Chairs:
    Shigenobu Takeda (Japan)
    Fei Chai (USA)
Terms of Reference
  1. Compile and synthesize available iron biogeochemistry data in the North Pacific;
  2. Review the past and ongoing laboratory, field and modeling studies on iron biogeochemistry and its impact on biological productivity and marine ecosystems in the North Pacific Ocean;
  3. Determine the natural supplies of iron to the North Pacific, which includes atmospheric dust transport and movement of iron-enriched waters, and examine linkages between iron supply and ecosystem responses;
  4. Identify gaps and issues related to experimental and modeling activities, encourage and plan national and international scientific programs on iron biogeochemistry and its impact on marine ecosystems in the North Pacific;
  5. Elucidate the role of iron as a potential regulator of harmful algal bloom (HAB) in coastal ecosystems of the North Pacific.
