The resistance value at any temperature is about 1/1000 the change in oxygen concentration.

There is a linear relationship between the oxygen concentration and the electrical current.

Photorespiration can occur when the oxygen concentration is too high.

Because of the variability in these factors, the final oxygen concentration is uncontrolled.

This allowed the oxygen concentration in the atmosphere to increase.

As with the rest of the Hudson, at the microbial level the bay's health is by oxygen concentrations.

When oxygen concentrations are low enough only bacteria and fungi can survive.

Fish need an average dissolved oxygen concentration of about 4 to 6 parts per million to stay alive.

This oxygen concentration suggested the existence of a "floor jet."

Low dissolved oxygen concentrations will indicate a potential problem in performing the test.
