Different lakes exhibit a range of catchment sizes, morphometry, and land use that contribute to differences in lake function. These functional differences mean that lakes vary in ecosystem services such as habitat quality and recreational value. In this module, students will explore high-frequency water quality datasets from several lakes around the world, graph high-frequency data, and use simple conceptual and mathematical models to calculate estimates of metabolism (gross primary production and respiration). Finally, students will compare metabolic rates across different lakes to examine gradients of eutrophication. Project EDDIE modules are designed with an A-B-C structure to make them flexible and adaptable to a range of student levels and course structures.

This entire module can be completed in one 2-3 hour lab period or two 1 hour lecture periods. Students will need 1-2 hours before class to prepare for the exercise. The module can be extended or shortened depending on how the instructor wants to present the PowerPoint slides.
This module has been used in several intermediate to upper-level freshwater ecology and limnology courses. Module materials can be tailored to increase or decrease the background information depending on students' familiarity with the material.
