ICES-IOC Working Group on Harmful Algal Bloom Dynamics (WGHABD)

The ICES-IOC Working Group on Harmful Algal Bloom Dynamics (WGHABD) was established in 1994 on the basis of a Study Group on the Dynamics of Algal Blooms created two years earlier. The aim of the working group is to outline the various physical, chemical and biological interactions associated to the harmful algal blooms (HAB) and to define the main gaps in research. The following list of topics, extracted from the working group reports, gives an impression of questions discussed in the WG:

 
  • algal population dynamics in relation to hydrodynamics processes
  • utility of mesocosm experiments for understanding algal population dynamics
  • cyst phase in the life histories of relevant, potentially harmful species
  • time and space scales of physical and biological processes relevant to studies on physical-biological interactions in HAB dynamics
  • ability of certain harmful algal species to adapt to and modify the microscale physical environment
  • efficacy of monitoring programmes in relation
  • impact of grazers on HABs and impact of HABs on recruitment of grazer populations
  • role of micro-organic nutrient dynamics and heterotrophic interactions in the initiation and maintenance of HABs
  • role of harmful benthic microalgae in benthinc and pelagic food web
  • role of ‘founding’ populations for HAB development

An important task of WGHABD is to collect information about harmful algal events in the ICES area. This information is stored in a joint IOC-ICES-PICES database, HAEDAT, which is a part of the IOC International Ocean Data exchange (IODE), and summarized as decadal maps through the cooperation with IFREMERACCESS TO HAEDAT.

WGHABD is co-operating with SCOR-IOC GEOHAB, and other ICES working groups like Working Group of Shelf Sea Oceanography and Working Group on Phytoplankton Ecology.

THE WORKING GROUP IS OPEN TO SCIENTISTS FROM ALL IOC MEMBER STATES. PLEASE CONTACT THE CHAIR OF THE WG, DR. EILEEN BRESNAN AT This email address is being protected from spambots.

The IOC HAB Programme may be able to support the participation to this working group of scientists from non-ICES countries (ICES is North Atlantic). If you are a candidate for this, please submit your application to This email address is being protected from spambots.

The 2014 meeting is scheduled for Ijmuiden, the Netherlands, 29 April to 2 May 2014.
