On Again, Off Again-The Dead Zone

This lesson plan introduces the science behind the causes, occurrence, and impacts of hypoxic or "dead" zones in coastal waters. Provides background, glossary, graphics for classroom activity, data files, and links to related projects and websites. Activities focus on: nutrient enrichment; dissolved oxygen; mechanisms of oxygen depletion. Students use data (real or simulated) to graph the hypoxic zone where the Mississippi River enters Louisiana's Gulf Coast.
