As aquatic microbes dine, they consume oxygen. When too many congregate at some temporary smorgasbord of goodies, they can use up so much oxygen that a so-called dead zone develops — water with too little oxygen to sustain fish, mammals or shellfish. On Sept. 7, federal scientists reported that despite the massive release of oil from the damaged BP well in the Gulf of Mexico, no such dead zone developed.
