1. The Gulf of Mexico Hypoxia Zone:

2. Mississippi River Basin

3. Gulf of Mexico- Major Inlets Laguna Madre Big Thicket Mississippi Delta Appalachicola Bay Everglades

4. Causes of Hypoxia Zone in Gulf Waters   Increase in nitrogen inputs to Gulf--nitrate concentrations have quadrupled in past 50 years   generation of wastewater   application of fertilizers   nitrogen fixation by leguminious crops   atmospheric deposition of oxidized nitrogen from fossil fuel combustion   Loss of natural wetland and vegetation along the banks has removed the watershed's nutrient-buffering capacity   River channelization for flood control and navigation has increased freshwater to the continental shelf.
