HAEDAT Harmful Algae Event Data-Base

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.
  htm1)
• 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

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.

• 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

24

• 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.

29
 In WGHABD report 1992 and in HAEDAT 1991.

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.

36
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 ....
