Dissolved Oxygen or DO is the free oxygen available in the atmosphere which dissolves in water. By-product of photosynthesis released during the day by aquatic plants. Photosynthesis can be summed up as: CO2 + H2O = CH2O+ O2. Glucose (CH2O) formed is used by the aquatic plant. The oxygen (O2) is released and dissolved in water.

The amount of water vapor in the air at the air-water interface increases as the temperature of water increases, which results in a decrease in oxygen concentration at the interface. The decrease is about 6% as the temperature of water changes from 32 o F to 100 o F. After oxygen is dissolved in water, it is the same temperature as the water.
