Climate change and eutrophication:
Anthropogenic eutrophication is the discharge of elevated concentrations of nutrients and organic matter to the sea. It causes especially in inshore and near coastal waters significant problems, such as elevated phytoplankton production, reduction of the light climate with limitation of macrophytes, accumulation of organic matter in bottom waters, oxygen depletion in bottom waters causing fish kills and kills of benthic organisms.
Climate warming will increase eutrophication by elevated nutrient discharges, extension of stratification by sea surface warming, prolonging the enclosure and oxygen depletion of bottom waters. By oxygen depletion complete benthic and pelagic ecosystems will be destroyed. The climatic enforcing of eutrophication processes requires an acceleration of measures to reduce nutrient discharges.
