Matt Rota | Heathy Gulf 1 August 2025 New Orleans, LA–Today, the official size of the 2025 Gulf Dead Zone was announced by NOAA-supported scientists. This year’s dead zone measured approximately 4,402 square miles, almost the size of Connecticut. While this is not the largest Dead Zone we have seen, it is approximately over [...]

31 July 2025 NOAA-supported scientists announced today that this year’s Gulf of America “dead zone” — an area of low to no oxygen that can kill fish and marine life — is approximately 4,402 square miles, 21% smaller than estimates from early June and the 15th smallest measurement on record. This equates to [...]

Margaret Kates | AL.com 21 August 2024 Patric Garmeson, a charter fishing captain, remembers “hundreds if not thousands” of dead bull redfish washed up in Bon Secour Bay in the spring of 2022. “When you set up a fishing trip, and then you realize that you’re in a dead zone, it can affect morale,” [...]
Doyle Rice | USA TODAY 1 August 2024 For decades, an oxygen-depleted "dead zone" that is harmful to sea life has appeared in the Gulf of Mexico in a region off Louisiana and Texas. This year, it's larger than average, federal scientists announced in a report out Thursday. The 2024 zone is about 6,705 [...]
Delaney Dryfoos | WWNO 2 August 2024 This year’s area of low oxygen in the Gulf of Mexico is larger than average, the National Oceanic and Atmospheric Administration (NOAA) announced on Thursday. The “dead zone” is approximately 6,705 square miles, as measured last week. Within NOAA’s 38 years of measuring the dead zone, this year’s assessment [...]
Mark Schleifstein | NOLA.com 1 August 2024 The annual “dead zone” in the Gulf of Mexico along Louisiana’s coast – an area where low to no oxygen in the deepest water can kill fish and other marine life – covered 6,705 square miles this summer, the 12th largest measured during 38 years of annual cruises, federal [...]
Eva Tesfaye | WWNO - New Orleans Public Radio 13 June 2024 The “dead zone” forms in the Gulf of Mexico every summer. It’s caused by nutrients such as nitrogen and phosphorus, largely from farm fertilizer and municipal runoff, which are carried down the Mississippi River and into the gulf. Algae feeds on those [...]
