  1. HAEDATHarmful Algae Event Data-Base IOC-IEO Science and Communication Centre on Harmful Algae Instituto Español de Oceanografía, Vigo, Spain.

  2. The ICES-IOC Working Group on Harmful Algal Bloom Dynamics has recorded harmful microalgae related events since 1987. • Increasing interest in data analysis led to a proposal in 1997 to create a computer data base of these events: the Harmful Algae Event Data Base (HAEDAT). • The main purpose of creating HAEDAT is to develop a structure for data storage that allows easy integration of data, efficient search tools, and the possibility of conducting powerful data analysis.

  3. HAEDAT has been available since October 1999 at the IOC web site (http://ioc.unesco.org/hab/data3.htm#1) • National reports from 1987 to 2003 have been entered. • 1109 reports are available on-line (1621 updated). • HAEDAT does not have share primary data. • HAEDAT shares: • Summary of data (species, where, when, conc., effects, etc). • Information on which data exist and where.

  4. Until now, HAEDAT must be downloaded from the Internet and runned under the Access  97 program. (~15.000 KB). • We are working now in a new format (MySQL/PHP on a Linux server) that will allow the on-line searchs.

  5. It is the ambition that HAEDAT will become the global database on harmful algal events. • There are some agreements with countries outside ICES: PICES, IOC-ANCA, IOC-FANSA IOC- HANA Mediterranean (Italy, Greece). • Missing: Rest of Mediterranean countries, AU, NZ, SE Asia, Central and Southern Africa.

  6. Inside the database you will find six different forms in which information has been structured:  ·         GENERAL INFORMATION ·         LOCATION AND DATE ·         MICROALGAE ·         ENVIRONMENT ·         HARMFUL EFFECTS ·         COMPLEMENTARY INFORMATION

  7. Old form • COUNTRY: 1.       Location: 2.       Date of Occurrence: 3.       Effects: 4.       Management decision: 5.       Causative Species: 6.       Environment: 7.       Advected population or in situ growth: 8.       Previous occurrences: 9.       Additional Comments: 10.    Individual to contact:

  8. Modified form for National HAB report • Available at the IOC Web site. • Locked form in Microsoft Word  (2pp). • National focal points will submit the national report to the IOC-IEO Science & Communication Centre on HA, in Vigo preferably by e-mail.

  9. ‘On line’ form • Available at the IOC Web site. • Any National focal points and National Monitoring Centres will have a password to fill in and edit their Reports ‘on line’.

  10. HAEDAT - MAPs

  11. Information plotted on maps • presence of toxins • or observations of mortalities • For each country: • the coast is divided into areas (~ 100 – 200 km) • For each area, dots of four different types: •  sampled, but no toxins detected •  one time (one year) • 2 – 5 times 6 – 10 times

  12. Maps are updated annually for the preceeding ten years by the IFREMER. • Modifications are provided by each country. • only pictures on maps • no data files

  13. IOC-ICES WGHABD 2002/2003: • Evaluate the usefulness and feasibility of creating HAE maps automatically from HAEDAT database. • HAEDAT will provide the detailed information behind the decadal maps.

  14. In WGHABD report 1992 and in HAEDAT 1991.

  15. Example of decadal map : ASP 1994 – 2003

  16. Example of annual map : 2003

  17. Later… with an improved link between HAEDAT & maps US-03-024. July-August 2003. max PSP : 365 µg STXeq / 100 g in blue mussels Alexandrium catenella.

  18. Distribution of G.catenatum in ES & PT (1987-2003)

  19. HAEDAT maps • The link between HAEDAT and Ifremer Map Product, is in process for ICES countries. • It can be extended to countries outside ICES and toother types of maps(annual maps, decadal maps, distribution of species). • It will allow in the next weeks / months to build maps almost automatically.

  20. HAEDAT next steps • Continued extension to information system, integrating further data related to the events described such as relevant taxonomies (IOC Ref. List), Monitoring Programmes (MON-DAT), etc ....
