On Again, Off Again - The Dead Zone

Abstract:

The purpose of the following series of activities is to help students visualize the dead zone and to provide them with dissolved oxygen (DO) data to analyze and interpret. Students will plot and analyze DO from the July 23-28, 1993, scientific cruise in the Gulf of Mexico. The activities are designed to engage the students individually, within a group and as a class to plot, observe, analyze and interpret several different spatial slices of the dead zone. In addition, these graphing activities can also be used to graph other variables such as salinity, density and temperature. The five graphing and mapping activities are described in order from simplest to most complex.
