Sites with dead zones (oxygen depletion on the sea bottom)

Year: 2008 Author: Hugo Ahlenius, UNEP/GRID-Arendal
Description:
Dead zones (hypoxic i.e. oxygen deficient water) in the coastal zones are increasing, typically surrounding major industrial and agricultural centers. This is commonly occuring due to nutrient pollution, in the form of nitrogen and phosphorous leading to algal blooms and eutrophication
