Co-chairs: Patricia Glibert (USA) and Lex Bouwman (Netherlands)

Other Full Members: Adnan Al-Azri (Oman), J. Icarus Allen (UK), Hans Dürr (The Netherlands), Paul Harrison (China-Beijing), Jorge A. Herrera-Silveira (Mexico), Sandor Mulsow (Chile), Sybil Seitzinger (USA), and Mingjiang Zhou (China-Beijing)

Associate Members: Arthur Beusen (Netherlands), Richard Gowen (UK), and Rencheng Yu (China-Beijing)

Terms of Reference

  • Integrate the existing IOC-HAB database and nutrient loading databases into a compatible GIS format.
  • Advance the development of a GIS coastal typology database.
  • Interrogate the above databases for relationships between HAB species, nutrient loading/forms/ratios, and coastal typology and develop broad relationships between nutrient loading and distributions of specific HABs. 
  • Explore possible changes in HAB occurrences in the future (year 2030), using the relationships developed above (3.) and global nutrient export patterns under the Millennium Assessment scenarios for 2030.
  • Publish the results of these analyses in peer-reviewed scientific journals. Papers will be developed on 1) the global perspective, including the next generation of global nutrient and HAB maps; 2) regional highlights; and 3) individual case studies.  We will also develop  articles for the GEOHAB newsletter and for the GEOHAB and Global News websites, and a graphic-rich report (under the GEOHAB umbrella) that will be targeted for management.
