Recent global warming has caused a major algal bloom on the seabed, suffocating flora and causing important biodiversity changes.Boris Horvat / AFP / Getty Images Dahr Jamail / Truthout June 25, 2018 [...]
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.

Researchers are offering different explanations for changing ocean oxygen concentrations rather than appreciating multiple causality. Credit: raiPR (CC0) Peter Brewer / Eos May 14, 2018 Widespread declines in ocean oxygen concentrations are now being reported with authors offering quite different explanations. Which ones are correct? Researchers are offering different explanations for changing [...]
Algal blooms that rob water of oxygen swirl across the Arabian Sea in 2015. New research indicates the sea has the world's largest low-oxygen 'dead zone.' Photo Credit: NASA Tristan Baurick / The Times-Picayune May 11, 2018 The Gulf of Mexico's dead zone is bigger than ever. Recent surveys put it at an [...]
Green algae swirls on the beach of Bandar al-Jissah in Oman on March 3, 2017. The Gulf of Oman turns green twice a year for about three months at a time, when an algae bloom spreads. Photo Credit: Sam McNeil, Associated Press CBC News May 2, 2018 U.K. researcher says area where [...]

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 [...]
