4 TERMS OF REFERENCE IN DETAIL8

4.1 Term of reference a: collate and assess national reports and update the decadal mapping of

harmful algal events for the IOC-ICES harmful algal database, HAE-DAT, on a regional, temporal

and species basis8

4.2 Term of reference b: review plans for the proposed Workshop on New and Classic Techniques

for the Determination of Numerical Abundance and Biovolume of HAB-species8

5.2 Background10

5.3 Term of reference c: Review progress in computerized production of decadal maps from

country reports, including revision of reports already in the database covering the last 10 years12

5.8 Term of reference h: consider the environmental dynamics and impacts of individual

phycotoxins and their metabolites enabled by new analytical technologies.15

5.9 Term of reference i: report and discuss new findings.16

5.10 Term of reference j: start preparations to summarise the distribution and number of harmful

algal blooms in the North Sea for the period 2000–2004, and any trends over recent decades in the

occurrence of these blooms for input to the Regional Ecosystem Study Group for the North Sea in

200619
