Abstract

The occurrence in May/June 1988 of a large and unexpected bloom of Chrysochromulina polylepis along the coasts of Denmark, Sweden and Norway, and the catastrophic consequences this had on fisheries and marine cultures, have drawn attention to the potential danger of North Sea eutrophication and to the unpreparedness of the European countries to take measures to avoid any recurrence of such accidents. In October 1989 the CEC organised a workshop on "exceptional" algal blooms in North Sea coastal areas. The proceedings of this workshop deal with ecological processes, processes determining nutrient inputs, the assessment of impacts of algal blooms and the economic assessment and optimisation of actions. Environmental factors controlling the development of algal blooms in different areas of the North Sea are reviewed. Existing models for the simulation of algal bloom dynamics are discussed and evaluated. Riverine nutrient inputs originate from domestic and industrial discharges as well as from agricultural soil runoff. Processes occurring in river systems and estuaries which have a considerable effect on the total nutrient load ultimately discharged into the sea are assessed. The harmful effects of excessive algal blooms on populations of fish, shellfish or benthic organisms are evaluated. Finally, eutrophication symptoms of northern European seas and actions to alleviate them are discussed and assessed.
