Does Salinity Decrease the Dissolved Oxygen Concentration in Water Samples?

[Soaring Crane]

Does salinity decrease the dissolved oxygen concentration in a water sample? For example, if one has two water samples, a freshwater sample and a seawater sample, at the same temperature, will the seawater sample have a lower dissolved oxygen concentration?

Thank you.

As Salinity increases, dissolved O2 decreases. Yes.

I also just finished a very very small study on this subject and came up with results supporting this statement
