Temporary dead zones are short lived dead zones lasting hours or days. Seasonal dead zones are annually occurring, typically in warm months of summer and autumn.
Since 1985, Rabalais has studied the Gulf of Mexico's dead zone off the coast of Louisiana, the largest hypoxic zone in the United States. Along with two other researchers, she linked hypoxic zones in the Gulf with Mississippi River estuaries in 1985 through ocean mapping oxygen levels.

A 'dead zone' off the Gulf coast is larger than NOAA predicted. The massive area poses danger to marine life, and recovery could take decades. A 'dead zone' is growing in the Gulf of Mexico.
Scientists prepare to collect near-bottom water aboard the R/V Pelican to verify oxygen measurements used to determine the size of the Gulf of Mexico hypoxic zone. (NOAA/LUMCON/LSU) A "dead zone ...

The Gulf of Mexico yields more fish, shrimp, and shellfish annually than the south and mid-Atlantic, Chesapeake, and New England areas combined. [6] The Smithsonian Institution Gulf of Mexico holdings are expected to provide an important baseline of understanding for future scientific studies on the impact of the Deepwater Horizon oil spill.

Tropical weather stirred up the Gulf of Mexico, reducing this year’s dead zone off Louisiana’s coast to the third-smallest ever measured, the scientist who has measured it since 1985 said Tuesday.
