Steve Hardy / The Advocate June 7, 2018 Once again, the Gulf of Mexico "dead zone" must be measured in the size of a U.S. state. LSU scientists predict this summer's iteration will exceed the size of Connecticut — about 6,620 square miles. The U.S. Geological Survey forecast 5,780 square miles. A tropical storm [...]

Doug Daigle / The Advocate June 7, 2018 2018 has become a pivotal year for the long-standing problem of the Gulf of Mexico Hypoxic Zone, commonly known as the “Dead Zone.” The large area of low oxygen that forms off Louisiana’s coast each year is fueled by nutrients such as nitrogen and phosphorus that [...]

Associated Press / The Times-Tribune June 7, 2018 Federal scientists are predicting an average dead zone this summer in the Gulf of Mexico. But they note that this would still be three times greater than the long-term goal for reducing the size of the largely human-caused area where there's too little oxygen to support [...]

This chart, published in the April 12, 2018, PLOS One journal, shows the Iowa portion of the total water discharge (blue bars), nitrate load (green bars) and land area (red line) in the Mississipi-Atchfalaya River Basin (MARB, Upper Mississippi River basin (UMRB), and Missouri River Basin (MoRB) from 1999 to 2016.
