Gulf of Mexico's "dead zone" smaller, more severe than expected - Breaking News from the Press-Register - al.com: "NEW ORLEANS -- The Gulf of Mexico's 'dead zone' - where there is too little oxygen in the water for anything to live - is less than half the size predicted earlier this year but also unusually severe, a scientist said Friday.

The hypoxic area forms every year in the Gulf, caused by bacteria feeding on algae blooms from the flow of farming runoff and other nutrients from the Mississippi River and others."
