Every year I try to measure a water quality depth profile in the middle of lake Liesjärvi. At every 1 m depth the temperature (degrees Celsius), pH, and conductivity (microSiemens) are measured in the middle of the lake were the lake is about 18.0-18.5 m deep.
relatively low temperatures. In summer (i.e. all other observations), differences in temperatures in the first two metres depend
on summer weather conditons. At 6 m depth temperature is constant with depth and varies between 8-10 degrees Celsius.
