Gulf of Mexico dead zone is largest on record | Ars Technica

This year’s “dead zone,” where oxygen levels are so low they threaten fish and other small aquatic life, is about 50 percent larger than normal. The average size of the dead zone over the last 31 years has been 14,037 square kilometers, according to Nancy Rabalais, a researcher at Louisiana State University who has long studied the issue. The dead zone was likely even larger than what the scientists found, but there was insufficient time on board the ship to measure its entire extent.
