I think that our hypothesis was correct bacause in Michigan, which is
alot colder, has an oxygen level of 16ppm. They had a water temperature
of 5(c). Our oxygen levels was an average of 9. With a water temperature
of 30(c). Also in Angelholm, Sweden, they had an oxygen level of 26ppm.
In conclusion, Oxygen levels have been proven to be higher in colder places
but lower in urban waters.
