In 2015 we took our incoming graduate students to Bear Lake and one part of this introductory course focused on the limnology of the lake.Students were taken out on the lake in two groups to measure temperature, oxygen and chlorophyll profiles.The boat was not anchored for the first sampling trip, and because of inclement weather, the boat drifted, making the vertical profiles problematic.With the second group the boat was anchored so that accurate depths would be recorded
