In this activity, students focus on the relationship between dissolved oxygen, plant growth, chlorophyll-a and temperature using SWMP water quality data from monitoring stations in the Narragansett Bay Estuarine Research Reserve and the...

This site is useful to find information about dissolved oxygen and the types of tests that are administered to determine the dissolved oxygen level.

Using data visualizations that show dissolved oxygen levels, students analyze the health of the Chesapeake Bay watershed. They will also learn about dead zones, which are aquatic areas where there is insufficient oxygen to support life....

The effect of changing pressure on the solubility of oxygen in water. Explains how temperature and pressure affect dissolved oxygen levels. Includes example formulas.

This site from the U.S. Geological Survey provides great definitions of seven measurements that can be taken on water. Includes pH, dissolved oxygen, and turbidity. Click Home to access the site in Spanish.

This activity introduces students to the complex chemistry of estuarine water. Students investigate how chemical and physical water quality factors-pH, temperature, dissolved oxygen, and salinity-change and interact over varying time...
