Nutrients In Chesapeake Bay DLESE Reviewed Collection
The Chesapeake Bay is the largest estuary in the US. Eleven rivers empty into the bay creating the Chesapeake Bay Watershed. From urban areas and cultivated fields in which wetlands were not preserved, runoff can run into the rivers unfiltered. This runoff can include nutrients that can cause uncontrolled growth of an abundance of algae which can eventually increase the turbidity of the river, not allowing light to reach the bottom of the river. This will result in the loss of sub-aquatic vegetation (SAV) as well as the organisms which rely on it for food and habitat. There are a variety of tests that can be conducted to determine the presence of algae in the rivers. Two of these tests include pH and turbidity. In this lesson which includes field work, students will measure water quality and use authentic satellite data to explore the effects of nutrients in the Chesapeake Bay and the rivers of its watershed.
