Web1. Students will be able to determine water temperature, salinity, and dissolved oxygen levels. 2. Students will be able to explain results using graphs. 3. Students will be able to explain the relationship between water temperature, salinity, and dissolved oxygen saturation. Abstract: WebDissolved oxygen is typically measured and reported as concentrations using either mg-DO/L of water (mg/L) or percent saturation as the units. Percent saturation refers to the amount of DO (percentage) dissolved in the water relative to the total amount possible. Figure 1.
