Terms of Reference

  • Establish a Web site to facilitate coordination of ongoing research worldwide, to create cohesion of efforts.
  • Make an inventory of aspects that relate to cycling of biogeochemically relevant elements. These aspects are

    • Factors regulating bloom inception
    • The grazing issue: bottom-up or top-down control
    • Cellular response to environmental factors
    • Distribution patterns: molecular-biological approaches
    • Genetics: pathways of distribution and biodiversity in the cluster
    • Emission of climate-relevant biogenic gases, and relevance for climate regulation
    • Cloud inception and characterisation of condensation nuclei over blooms
    • Sensitivity of climate models for presence of plankton, in casu the Phaeocystis cluster
  • Meet once a year to discuss progress, and divide tasks to arrive at a series of chapters produced under the responsibility of members of the Working Group.
  • In the last year, write a series of reviews covering the subjects mentioned under Term of Reference #2, which will be the chapters of a book that will be produced as the product of the Working Group. At least two Working Group members will be responsible for each chapter.
