High Mississippi River outflow and Hurricane Barry could influence final size
NOAA and its academic partners will report on their recent research cruise to measure the extent of the hypoxic or “dead zone” in the Gulf of Mexico during a media teleconference on Thursday, Aug. 1. Researchers will address how record-high outflow from the Mississippi River and Hurricane Barry might have influenced the final size of the hypoxia zone.
In June, NOAA scientists had forecasted this summer’s dead zone – an area of low to no oxygen that can kill fish and other marine life – to be approximately 7,829 square miles. This measurement is a key metric used by the Mississippi River/Gulf of Mexico Hypoxia Task Force to determine progress toward meeting its nutrient reduction goals. The annual prediction is based on U.S. Geological Survey river flow and nutrient data.
The 2019 forecast is close to the record size of 8,776 square miles set in 2017 and larger than the 5-year average measured size of 5,770 square miles.
Media teleconference on the final estimate of the size of the Gulf of Mexico dead zone, following up on the June forecast, and a Q&A session.
