During seven research cruises in 2001, pelagic organisms were collected at four locations in the German Bight and at four locations in a transect from an oil platform in the North Sea. The studied systems and organisms range from bacteria through zooplankton and fish larvae to juvenile and adult fish (saithe, mackerel and herring). Endpoints in the studies, performed by laboratories in 10 different European countries, include community studies as well as a suite of biomarker methods. The biomarkers include MT concentration, EROD activity, AChE activity, GST activity, histopathology, histochemistry, vtg and zrp concentration, CYP mRNA levels, DNA damage, PAH metabolites, antioxidant enzyme induction and cellular energy allocation. Selected tissues are extracted for bioassay studies. Chemical analyses are underway for the same organisms and tissues. The design of the sampling and preliminary results will be presented.
