Gulf dead zone grows, perplexes scientists

Article Abstract:

The hypoxic region in the Gulf of Mexico extends 7728 square miles, but the cause for the region's growth continues to elude scientists. The region is a dead zone within the Gulf of Mexico where the water is depleted of oxygen. The popular theory is that the runoff of phosphorous, nitrogen and silica from the Atchafalaya and Mississippi Rivers is the cause of the hypoxia. Such regions in other areas have resulted in the collapse of fisheries.
