    The Kattegat, characterised by widespread anoxia, [15] was one of the first marine dead zones to be noted in the 1970s, when scientists began to study the effects of heavy industry on the natural world. [16] [17] Since then, research has leant much insight into processes like eutrophication, and how to deal with it.

  9. Hypoxia (environmental) - Wikipedia

    en.wikipedia.org/wiki/Hypoxia_(environmental)

    The exaerobic zone is found at the boundary of anoxic and hypoxic zones. Hypoxia can occur throughout the water column and also at high altitudes as well as near sediments on the bottom. It usually extends throughout 20–50% of the water column, but depends on the water depth and location of pycnoclines (rapid changes in water density with depth).
