Scientists say West Coast waters now have a hypoxia season, or dead-zone season, just like the wildfire season. Hypoxia is a condition in which the ocean water close to the seafloor has such low levels of dissolved oxygen that the… Read More ›

“As discussed in the press release, there still remains a need to reduce the nutrient load entering the Gulf of Mexico and the smaller observed size was likely a result of storm and wind conditions and are not necessarily an indication of a long-term decrease in hypoxia area,” said Keeley Belva, a spokeswoman for the National Ocean Service.
Intensive agriculture near the Mississippi has led to fertilizers leeching into the river, and ultimately the Gulf of Mexico, via soils and waterways. This has resulted in a huge oxygen-deprived dead zone in the Gulf that is now at its largest ever extent, covering an area greater than the state of New Jersey.
The gulf dead zone is only one piece of a larger, environmental problem with U.S. agriculture and watershed issues, however. The gulf just happens to be one of the areas where effects of agricultural practices and pollution are more visible. These kind of problems, though, are far reaching, effect the whole country and are heavily tied to government and industry.
Some good may come from climate change after all. Dead zones, the most oxygen deprive portions of our world’s oceans, may actually be due for some shrinkage due to changing atmospheric patterns and water temperatures, according to a recently study…. Read More ›
