In fall months, tropical storms begin to enter the Gulf of Mexico and break up the dead zones, and the cycle repeats again in the spring. Aquatic and marine dead zones can be caused by an increase in nutrients (particularly nitrogen and phosphorus) in the water, known as eutrophication. These nutrients are the fundamental building blocks of ...
A 'dead zone' off the Gulf coast is larger than NOAA predicted. The massive area poses danger to marine life, and recovery could take decades. A 'dead zone' is growing in the Gulf of Mexico.
Every spring, an area appears when the water doesn't have enough oxygen to support fish and other marine life. Skip to main content. News. 24/7 help. For premium support please call: ...

Red circles show the location and size of many dead zones (in 2008). Black dots show dead zones of unknown size. The size and number of marine dead zones—areas where the deep water is so low in dissolved oxygen that sea creatures cannot survive (except for some specialized bacteria)—have grown in the past half-century.

An example of this is the dead zone located off the coast of the Mississippi River. According to NOAA , the 2016 predicted size of this dead zone is going to be approximately 5,898 square miles with a nitrate concentration of 146,000 metric tons of nitrate flowing down the Mississippi and Atchafalaya River into the Gulf of Mexico.

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 ...
