The dead zone in the Gulf of Mexico covers a smaller area but is far deeper this year than in the past, according to a new report by Nancy Rabalais (1999), who has been studying the problem for years. Rabalais and several other scientists whose work is supported by the National Oceanic and Atmospheric Administration discussed their findings in a teleconference on July 27 attended by NOAA administrator Jane Lubchenco. Agricultural runoff from farms along the Mississippi River remains a major cause. Read recent coverage in Scientific American, the Miami Herald, and Bloomberg.com.
