• 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.

Page 3: HAEDAT Harmful Algae Event  Data-Base

• 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.

Page 4: HAEDAT Harmful Algae Event  Data-Base

• 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.

Page 5: HAEDAT Harmful Algae Event  Data-Base

• 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-FANSAIOC- HANA Mediterranean (Italy, Greece).

• Missing: Rest of Mediterranean countries, AU, NZ, SE Asia, Central and Southern Africa.

Page 6: HAEDAT Harmful Algae Event  Data-Base

• 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

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.

‘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’.

HAEDAT - MAPs

Page 21: HAEDAT Harmful Algae Event  Data-Base
Page 22: HAEDAT Harmful Algae Event  Data-Base
Page 23: HAEDAT Harmful Algae Event  Data-Base

•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

Page 24: HAEDAT Harmful Algae Event  Data-Base

•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

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.

Page 29: HAEDAT Harmful Algae Event  Data-Base

 In WGHABD report 1992 and in HAEDAT 1991.

Example of annual map :

Later… with an improved link between HAEDAT & maps

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 to other types of maps (annual maps, decadal maps, distribution of species).

• It will allow in the next weeks / months to build maps almost automatically.

Page 36: HAEDAT Harmful Algae Event  Data-Base

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 ....
