Summary
Hypoxia and anoxia are to a certain extent natural phenomena in many deep fjords. Since the early 1980s, more or less widespreadhypoxia has been observed nearly every autumn in Danish coastal waters. The causes of hypoxia in Denmark are related to increased nutrient loads and natural physical factors (e.g. weather) affecting the timing and scale of hypoxia. The response of marine benthic macrofaunal communities to seasonal hypoxia iscollapse or mass mortality.
