HAEDAT

Harmful Algae Event Data-Base

IOC-IEO Science and Communication Centre on Harmful Algae

Instituto Español de Oceanografía, Vigo, Spain.

• 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.

• 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.

• 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.

• 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.

• 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

•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

•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.

 In WGHABD report 1992 and in HAEDAT 1991.

Example of decadal map :

ASP1994 – 2003

Example of annual map :

2003

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.

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 ....
