The purpose of this experiment was to find how atmospheric temperature affects the dissolved oxygen rate in the Ottawa River. Prior to the experiment, there was much research done and effort put into designing the most effective test. This experiment was conducted using measured dissolved oxygen compared to the atmosphere's temperature, over the span of 28 days. The dissolved oxygen rate fluctuations ranged from 5 to 8 ppm mg/L, with atmosphere temperature also variating. The hypothesis was that if the air temperature decreases, then the dissolved oxygen level will increase, because as air molecules slow down, there are less oxygen molecules from water being released into the atmosphere. During the experiment, there were some obstacles and setbacks, but in the end there were intriguing results that can be used by future scientists to learn more about dissolved oxygen and its relationship with atmospheric temperature.
