NOAA, partners to report on 2022 Gulf of Mexico ‘dead zone’ monitoring cruise

NOAA and its partners will report on their recent research cruise to measure the extent of the hypoxic area, or “dead zone,” in the Gulf of Mexico during a media teleconference on Wed., Aug. 3 at 1 p.m. EDT.

In June, NOAA scientists forecasted this summer’s dead zone –– an area of low to no oxygen that can kill fish and other marine life –– to be approximately 5,364 square miles. That is smaller than, but close to, the five-year average measured size of 5,380 square miles, and substantially less than the record of 8,776 square miles set in 2017.

Speakers will discuss factors affecting the measured size of this year’s dead zone and potential effects to living resources, the accuracy of the spring hypoxia forecast and ongoing federal and state efforts in the Mississippi River watershed to reduce nutrient inputs entering the Gulf. 


Media teleconference on the measured size of the Gulf of Mexico dead zone and efforts to predict and mitigate its effects, followed by Q&A.


Wed., Aug. 3, 1:00 p.m. EDT
