Diel cycling hypoxia is a specific seasonal dead zone that only becomes hypoxic during the night; The type of dead zone can, in some ways, be categorized by the time required for the water to return to full health. This time frame depends on the intensity of eutrophication and level of oxygen depletion.

Since liquid water flows, ocean waters cycle and flow in currents around the world. Since water easily changes phase, it can be carried into the atmosphere as water vapour or frozen as an iceberg. It can then precipitate or melt to become liquid water again. All marine life is immersed in water, the matrix and womb of life itself. [7]
A dead zone is an area of water that cannot sustain aquatic life because the oxygen levels are low or depleted. The scientific term for a dead zone is called hypoxia, which in Latin means "too ...

Dead zones are hypoxic, meaning the water has very low levels of dissolved oxygen. This kills off marine life or forces it to leave the area, removing life from the area and giving it the name dead zone. Hypoxic zones or dead zones can occur naturally, but nutrient pollution from human activity has turned this natural process into an ...
When nitrogen in the form of nitrate is in excess, it can lead to a dead zone. A dead zone is a body of water that has a depleted oxygen concentration that is low and can lead to the suffocation of animals. [4] An example of this is the dead zone located off the coast of the Mississippi River.
