This year, the dead zone in the Gulf of Mexico entered into the top third of largest dead zones in records that go back 38 years, the National Oceanic and Atmospheric Administration said. The ...
Scientists from Louisiana State University found a massive dead zone in the Mississippi Sound while conducting their annual survey in the Gulf of Mexico. The dead zone stretches from the ...
Some assert that the dead zone threatens lucrative commercial and recreational fisheries in the Gulf of Mexico. "In 2009, the dockside value of commercial fisheries in the Gulf was $629 million. Nearly three million recreational fishers further contributed about $10 billion to the Gulf economy, taking 22 million fishing trips."
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.
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 oxygen concentration in the bottom layer may then become low enough for hypoxia to occur. Areas particularly prone to this include shallow waters of semi-enclosed water bodies such as the Waddenzee or the Gulf of Mexico, where land run-off is substantial. In these areas a so-called "dead zone" can be created.
The Gulf of Mexico (Spanish: Golfo de México) is an ocean basin and a marginal sea of the Atlantic Ocean, [3] [4] mostly surrounded by the North American continent. [5] It is bounded on the northeast, north, and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexican states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatán, and Quintana Roo; and on the ...
Just one year away from a 2025 deadline to reduce nitrogen and phosphorus entering the gulf by 20%, success seems unlikely, and the dead zone persists in size, choking thousands of square miles in ...
