Temporary dead zones are short lived dead zones lasting hours or days. Seasonal dead zones are annually occurring, typically in warm months of summer and autumn.
Firstly, it occurs in coastal zones where eutrophication has driven some quite rapid (in a few decades) declines in oxygen to very low levels. [2] This type of ocean deoxygenation is also called dead zones. Secondly, ocean deoxygenation occurs also in the open ocean. In that part of the ocean, there is nowadays an ongoing reduction in oxygen ...

[4] [5] Later, Schultz [6] would use it with ecological and physiognomical criteria, in a way similar to the concept of biome.

Ecological death is the inability of an organism to function in an ecological context, leading to death. [1] This term can be used in many fields of biology to describe any species .
