Harmful Algal Blooms(HAB)
What are Harmful Algal Blooms?
A proliferation of unicellular phytoplankton which can cause massive fish or shellfish kills. HAB contaminates seafood with toxins and alters aquatic ecosystems in ways that humans perceive as being harmful. There are two phenomena, so-called Red Tide and Toxin-Producing plankton.
WG3 is the main body of the activities on coastal environmental assessment, which is a high priority issue of CEARAC. WG3 especially focuses on Red Tides and Harmful Algal Blooms (HABs).
1.Achievements in the past (-2007)
WG3 summarized the information on HAB occurrence in the member states and published the National Report and the Integrated Report on HABs to understand current situations. In the Integrated report, various kinds of HAB-related information in each member state were summarized and necessary future activities in this region were clarified.
WG3 established two websites to distribute useful information on HABs in the NOWPAP Region.
WG3 collected countermeasures against HABs, which have been implemented and/or under study in each member state to promote mitigation of HABs in member states, and published "Booklet of Countermeasures against HABs in the NOWPAP Region".
IV. Public awareness materials (2007)
WG3 made Cochlodinium pamphlet in the NOWPAP members’ languages and English to disseminate information widely.
2. Activities in 2008-2009
I. Implementation of HAB Case Studies
WG3 implements HAB Case Studies in the NOWPAP Region to establish the most effective and laborsaving methods to share HAB related information (HAB occurrences, oceanic and meteorologic conditions) and make reports. These case studies will be implemented in 1 or 2 selected sea area(s) in each member state where HABs occur frequently or occurrence is concerned in the near future.
II. Development of HAB Integrated Website
WG3 develops HAB Integrated Website to share the past achievements and data collected by HAB Case Studies among not only NOWPAP member states but also other international organizations. Through this website, CEARAC promotes cooperation with other Regional Seas Programmes and international projects.
As a joint activity of WG3 and WG4, "Procedures for assessment of eutrophication status including evaluation of land based sources of nutrients for the NOWPAP region (Common Procedures)" were be developed by utilizing RS techniques.
