**CAUTION: Remember to switch to mg/l mode before making oxygen measurements.** Depth (ft.) Temp (oC) DO (mg/l) Depth (ft.) Temp (oC) DO (mg/l)
Dissolved oxygen concentration is reported in units of mg/l, or milligrams per liter (mg/l is also referred to as parts per million (ppm) because a liter is 1000 grams of fresh water, and a milligram is a millionth of that). Percent saturation is reported in units of percent. Oxygen dissolves in water to saturation, a value typical of a given temperature. Percent saturation tells us what part

water temperature naturally affect the concentration of dissolved oxygen in the water, but human impacts from farming and urban development can lead to very low, unhealthy levels of dissolved oxygen in the bay.)
Depletion of dissolved oxygen occurred simultaneously in the bottom waters of both tributary arms in the upstream part of the reservoir and was due to reservoir stratification.
Oxygen gas is dissolved in water by a variety of processes—diffusion between the atmosphere and water at its surface, aeration as water flows over rocks and other debris, churning of water by waves and wind, and photosynthesis of aquatic plants. There are many factors that affect the concentration of dissolved oxygen in an aquatic environment. These factors include: temperature, stream flow

Temperature Salinity Dissolved Oxygen and Water Masses

In aquatic environments, oxygen saturation is a ratio of the concentration of dissolved oxygen (O 2) in the water to the maximum amount of oxygen that will dissolve in the water at that temperature and pressure under stable equilibrium.
Maximum Dissolved Oxygen Concentration Saturation Table The concentration of dissolved oxygen (DO) in water is influenced by a number of factors, including water temperature, salinity and atmospheric pressure.
