Dissolved Oxygen Percent Saturation at the Runnin’s River

The measurements in the graph were taken from the Runnin’s River in early September, 2006, at two different sites. From the graph, it is evident that the dissolved oxygen percent saturation level at Site A was at a high of approximately 128 within the first hour.  However, throughout the remaining time period, the percent of dissolved oxygen saturation remained constant. Similar to Site A, Site B had a relatively constant level of dissolved oxygen percent saturation throughout the twenty-four hour measuring period.  Highs for the oxygen saturation level were within the first hour of measurements at approximately 84. From the graphs it is clear that water temperature did not remain constant during the twenty-four hour measuring period.  Throughout the first nine measurements, the temperature steadily increased at both sites, before gradually decreasing as the day progressed into the evening hours.  The temperature continued to drop at both sites, until the sun rose high enough the following day to warm the water.  Nevertheless, the temperature at Site A and Site B was relatively equivalent.
