Area of Global Dead Zones Doubling Every 10 Years

A diver observes filamentous algae, locally known as thanatos, at La Ciotat in the Mediterranean sea, on July 4, 2015. 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 The [...]

Gulf of Mexico ‘Dead Zone’ expected to be larger than Connecticut this summer, scientists say

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 could [...]

Guest column: A call for help on Dead Zone

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 flow [...]

Scientists Predict Average Dead Zone, But 3x Long-Term Goal

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 marine [...]

Study: Iowa ‘main contributor to nitrate loads’

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.

Multiple Choices Exist for Changing Ocean Oxygen Concentrations

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 ocean [...]
