2018 Hypoxia Forecast

“The June 2018 forecast of the size of the hypoxic zone in the northern Gulf of Mexico for late July 2018 is that it will cover 17,250 km2 (6,660 mi2) of the bottom of the continental shelf off Louisiana and Texas. The 95% confidence interval is that it will be between 14,628 and 19,727 km2 (5,648 and 7,617 mi2).”

What is hypoxia?

Hypoxia, or low oxygen, is an environmental phenomenon where the concentration of dissolved oxygen in the water column decreases to a level that can no longer support living aquatic organisms. Hypoxic areas, or “Dead Zones,” have increased in duration and frequency across our planet’s oceans since first being noted in the 1970s.

The largest hypoxic zone currently affecting the United States, and the second largest hypoxic zone worldwide, is the northern Gulf of Mexico adjacent to the Mississippi River.
