Ziel der Reise / Objectives of Cruise:

NORCOHAB (North Sea Coast Harmful Algal Bloom Study) Objective: To study teh coastal oceanographic Processes and mechanisms underlying the dynamics of key toyic bloom species and the biogeographical distribution of their toxins in the water column of different North Sea coastal waters. For the first time, on board measurements of known phycotoxins collected directly from the plankton were subjected to analysis by high resolution tander mass spectrometrty coupled with liquid chromatography (LC-MS/MS). These measurements included domoic acid and a large variety of lipophilic toxins associated with marine plankton. We also perfomed grazing experiments with protists and copepods on selected key toxin algal species in on board incubations. The following main goals of the cruise programme were successfully addressed: 1) the phenotypic and genotypic characteristics of populations of selected HAB species were compared, including that of a new dinoflagellate identified as the proximal source of azaspiracid polsoning (AZP) In the North Sea 2) the toxin profile and content of HAB species and toxin transfer and metabolism to the next trophic level were assessed and compared; and 3) insights into the relative importance of grazing by both metazoa and protists as a potential "top down"
