US Long-Term Ecological Research Network

We sample at the deepest part of the lake, taking a temperature and oxygen profile at meter intervals from the surface to within 1 meter of the bottom using a YSI Pro-ODO temp/DO meter.  We sample biweekly during open water and approximately every five weeks during ice cover.

Protocol Log:  Prior to 2011, we used a YSI Model 58 temp/DO meter.
