In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrient Enhanced Coastal Ocean Productivity (NECOP) Program. Learners use the dissolved oxygen data to construct a graph illustrating the "dead zone" in the Gulf of Mexico, practice data manipulation using Microsoft Excel (or graph paper), and recommend solutions for hypoxia, threatening marine life. This resource includes two links to optional follow up activities.
