Hypoxia Press Release and Map - August 1, 2005

EPA- Gulf of Mexico Program Office

This EPA press release documents the findings of a 2005 mapping project in the Gulf of Mexico low-oxygen waters. The article notes the extent of the "dead zone" and notes the possible effects of Hurricane Dennis on the hypoxic zone. It also reports a smaller than expected nitrate content in the dead zone, which was attributed to the below average precipitation in the Mississippi River Basin. The press release also features a color map of the dead zone's extent.
