Rabalais, who is also a distinguished research professor at LSU’s Marine Consortium, told Truthout the dead zone in the Gulf of Mexico has, over the 31 years it has been measured, averaged 5,806 square miles in size.

“It remains the second-largest human-caused low oxygen area in global coastal waters,” said Rabalais, who discovered the Gulf dead zone and has been tracking it ever since. “In 2017, it was the largest ever measured: 8,776 square miles.”

Her and her colleagues’ research has also shown that there are now more than 400 coastal low-oxygen areas around the globe, and the number of dead zones started to double roughly every decade beginning in the 1960s.
