The option that best describes dissolved oxygen is that water with high salinity has low dissolved oxygen.
Solubility of oxygen in water
Oxygen is an element that is abundant in nature and has the ability to dissolve in water. It's ability to dissolve in water makes it suitable for aquatic life.
However, it's solubility in water depends on the salinity, pressure and temperature of water.
For temperature, the solubility of oxygen decreases as temperature of water increases.
Therefore warmer water should allow for less dissolved oxygen.
For salinity, dissolved oxygen decreases exponentially as salt levels increase in water. Therefore, water with high salinity has low dissolved oxygen.
