Dead Zone
The Dead Zone is located in The Gulf of Mexico right where the Mississippi empties out. ... It is called the Dead Zone because there is little to no life there this is because of the low oxygen level or Hypoxia. ... The dead Zone usually forms in May but sometimes as early as February and usually lasts until early September late October. ... 6 million metric tons of nitrogen enters the gulf each year and close to 1 million metric tons of this is nitrate (the most important nitrogen involved in the creation of the Dead Zone). ... That summer the hypnotic zone doubled in size. In 1988 there was a huge drought in the Midwest and the hypnotic zone was almost absent proving the Mississippi obviously is the source of this problem and has influence on what happens to the gulf.
