Figure 3. Example of daily water temperature fluctuation at the Gulf Jackson lease area, Levy County, Florida, on October 24, 2003. Dissolved oxygen is shown as A) mg/L, and B) % saturation. On October 24, temperature fluctuated by only 2.5°C (4.5°F) and, therefore, the variation in % saturation due to temperature change was relatively small. As a consequence, graph A and B look similar.
