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 [...]

Which ones are correct? Researchers are offering different explanations for changing [...]

Doyle Rice / USA TODAY 26 March 2018 The annual “dead zone” in the Gulf of Mexico, which last year was the size of New Jersey, will continue for several decades, a new study said. A dead zone occurs at the bottom of a body of water when there isn't enough oxygen in the water to [...]

By JANET McCONNAUGHEY/ AP Mar. 22, 2018 NEW ORLEANS (AP) — The Gulf of Mexico’s “dead zone” will be an unwanted summer visitor for decades, Canadian scientists say. They say the oxygen-starved patch would persist even if farmers could immediately end all fertilizer runoff. An area with too little oxygen to support marine life [...]
