Students use the Dissolved Oxygen Probe to measure the concentration of dissolved oxygen in water from streams and rivers. They correlate the availability of dissolved oxygen to temperature, pressure, and salinity.

If students are sampling from several locations, Events with Entry can be used to collect the data.
