Its to do with the solubility of oxygen in water. oxygen has the highest solubility in water at a certain temperature (I don't know exactly what it is), but it would be somewhere between 0 and 100 deg C. Above this critical temperature the desolved oxygen will be at its highest. anything below that the oxygen levels will be lower.

Hi. From the web: "The level of dissolved oxygen can decrease in several ways, primarily through increased aerobic microbial action. It can also decrease from increases in water temperature."

well, it would make sense that the colder the water, the less dissolved oxygen is found, due to the fact that colder water molocules are closer together, leaving less space for dissolved oxygen. the warmer the water, the more space for dissolved oxygen. i haven't actually studied this, so it might be different, i am just using common sense, but i hope this helped!

The concentration of O2 is greater in colder water. The references give the explanations and have tables to show this. They also include methods of measurement.
