This comprehensive report reflects the views of the US research and management community about the current state of HAB problems, needs and priorities, and approaches available to address these problems. The major research priorities and capacity needs identified by the report fall into four categories: bloom ecology and dynamics; toxins and their effects; food webs and fisheries; and public health and socioeconomic impacts.


The mission of the National HAB Committee (NHC) is to facilitate coordination and communication of activities for the U.S. HAB community at a national level.

The National Harmful Algal Bloom Committee (NHC) has been established for the purpose of providing a collective voice of the academic, management and stakeholder communities interested in national HAB issues.  The need for such a committee was identified in HARRNESS (Harmful Algal Research and Response: A National Environmental Science Strategy (2005)) - the new U.S. National Program for HABs.

The NHC will:

  • Facilitate implementation of HARRNESS (PDF) and garner support among all stakeholders
  • Interface with the Interagency Working Group on HABs, Hypoxia, Human Health
  • Foster communication between all components of the HAB community and communicate these activities through the National HAB Office, through oral reports at the biennial National HAB Conference, and through listserves and websites as appropriate
  • Establish and promote interactions with related national and international programs by interfacing  with related national and international initiatives, such as GEOHAB, IOOS, GOOS, CUAHSI, CLEANER, NEON, and ORION
  • Respond to requests from Congress or federal and state entities for information or guidance on HAB issues
  • Respond to other stakeholders as appropriate
  • Lead development of future National HAB Plans as needed
  • Form ad hoc technical advisory committees as needed to address issues or requests
  • Raise the visibility and understanding of HAB issues nationally
