North Sea Nutrients and Eutrophication

  • Chapter
Pollution of the North Sea

Abstract

The term “nutrient” refers to the biologically available inorganic forms of nitrogen, phosphorus, and silica. Unlike carbon, these elements, which are among the major constituents of living organisms, are often present in short supply with respect to the needs of petoplankton in marine ecosystems. Because of this, primary production and phytoplankton standing crop are highly dependent on nutrient concentrations and the processes regenerating nutrients from the organic compounds where they have been incorporated. Input of nutrients from external sources also considerably affects primary producers and the whole ecosystem, sometimes in an undesirable way causing “eutrophication” effects.
