Abstract

The phytoplankton synthesizes higher organic substances from anorganic matter and sunlight and normally drives the limnic and maritim ecosystems. The scientists use classical methodes (Draw Water, Cell-counting, Extraction of Chl a, ¹⁴C-Method, O₂ Productionrate) to monitor the concentration, the population and the primary production, and recently more physical methodes become usual.
