12th International Conference on Harmful Algae

INTERNATIONAL SOCIETY FOR THE STUDY OF HARMFUL ALGAE12 th <strong>International</strong> <strong>Conference</strong> on Harmful Algae, Copenhagen, Denmark, 4-8 September 2006the PSP- producing speciesGymnodinium catenatum andAlexandrium tamarense and severalenvironmental factors in the period1991-2004. The study zoneincluded three Uruguayan coastallocations along a 140-km stretch:Piriápolis, Punta del Este andArachania. The relation betweenweekly abundance of the twospecies, water temperature, salinity,temperature anomalies, seawatertemperature (SST 3.4 Index) fromNOAA, and Río de la Plata wasanalyzed.The A. tamarense blooms higherthan 10,000 cells/l occurredbetween 11 and 14 ºC, 17.3 and32.2 psu, without strong incidenceof temperature anomalies, and aRio de la Plata flow between 17,000and 23,000 m 3 /s. Gymnodiniumcatenatum blooms occurredbetween 21.8 and 24 ºC, generallyunder positive anomalies of seasurface temperature, with salinitiesfrom 18.4 to 32 psu, under higherRio de la Plata flow dischargebetween 18,000 and 34,000 m3/s.PO.15-23California Program for RegionalEnhanced Monitoring ofPhycoToxins (Cal-PReEMPT)Session: PO.15 - MonitoringP E Miller 1 , GW Langlois 2 , RM Kudela 1 ,MW Silver 11 University of California, Santa Cruz,SANTA CRUZ, United States of America2 California Department of Health Services,RICHMOND, United States of AmericaCalifornia’s expansive coastline isthreatened by blooms of a variety ofharmful algal genera, includingPseudo-nitzschia and Alexandrium.Efficient and cost-effective newmethods for species and toxindetection have been developed, ashave remote sensing capabilities forbloom tracking. Although thesetechnologies are available, aconstraint to adoption of them bythe California Department of HealthService (CDHS) is the lack of fundsfor ground-truthing them, anecessary step before full adoptionand incorporation into the state’smonitoring effort. To bridge the gulfbetween availability of new toolsand integration of those intomonitoring efforts, NOAA, throughits Monitoring and Event ResponseProgram for Harmful Algal Blooms(MERHAB), is providing funding toperform necessary validation of newtools for incorporation of them intothe CDHS monitoring program. Wehave established pilot project siteswhere new technologies areincorporated into an intensivemonitoring program. Our approachis to shift much of the monitoringeffort to the field, where fieldtechnicians pre-screen samples fortoxins and toxin-producing species,thus ensuring early warning ofimpending blooms while avoidingun-necessary and expensive labbasedsample testing. Thispresentation will provide anoverview of our MERHAB-fundedprogram, detailing our progress andaccomplishments to date.PO.12-09Molecular phylogeny andultrastructural studies of theperiflagellar area of some benthicspecies of Prorocentrum(Dinophyceae)Session: PO.12 - Taxonomy andPhylogenyNormawaty Mohd Noor, NielsDaugbjerg, Øjvind MoestrupBiological Institute, COPENHAGEN K,Denmark240
