  1. Spring Water Quality Survey
    Survey objective: The U.S. Environmental Protection Agency’s Great Lakes National Program Office (GLNPO) is responsible for monitoring the offshore water quality of the Great Lakes to evaluate water quality over time and identify any emerging water quality problems. Comprehensive water quality surveys are conducted in all five Great Lakes in both the spring, when the water is cold and well mixed, and in the summer, when the surface waters are warmer and the lakes are stratified and more biologically active. The R/V Lake Guardian is used to conduct the surveys.
