Lake Profiles

The Floating Classroom offers two options for collecting physical and chemical water quality data at specific depths from Cayuga
Lake.  For most groups, our manually-operated Van Dorn samplers are perfect to encourage teamwork and direct collection and measurement of water samples.  For more advanced classes, we offer the use of a remote sensor (HydroLab sonde).  Field parameters may include:
    Level 1- Depth, Temperature, pH
    Level 2- Dissolved oxygen, specific conductivity,
    Level 3- Alkalinity, carbon dioxide & chlorophyll.
Our goal for most cruises, each research team will collect one or more depth-specific samples, and the results will be combined to create a LAKE PROFILE or a range from the surface to the hypolimnion.  This information is directly related to the biological (plankton) and clarity/solar energy penetration (Secchi Disk) observations made at other stations during a cruise. 
Example temperature profiles are available here, and a video demonstration of the Van Dorn sampler is here.  More information is soon to be available!! 
Extension Applications
  • Identification of the THERMOCLINE
  • Lake turnover
  • Heat storage and release from the lake (creating a micro-climate)
  • Energy and nutrient distribution as a function of water DENSITY
  • Generation and Interpretation of plotted data.
