What is the term for oxygen gas that is absorbed and mixed into water?

Dissolved oxygen refers to the amount of oxygen that is present in water, where it is absorbed and mixed into the liquid. This oxygen is crucial for aquatic life, as fish and other organisms rely on it for respiration. In natural bodies of water, oxygen can be dissolved through various processes, including diffusion from the atmosphere, turbulence created by wind or waves, and photosynthesis performed by aquatic plants.

While saturation oxygen refers to the maximum amount of oxygen dissolved in water at a specific temperature and pressure, the term itself does not describe the process of oxygen being absorbed in the water. Oxygenation and aerated oxygen relate to the act of adding oxygen to water, but they do not specifically denote the oxygen that is already dissolved. Therefore, the most accurate term for oxygen gas that has been absorbed and mixed into water is dissolved oxygen.
