How does temperature affect dissolved oxygen levels?

The solubility of oxygen is greater in colder water than in warm water. Oxygen slips into “pockets” that exist in the loose hydrogen-bonded network of water molecules without forcing them apart. The oxygen is then caged by water molecules, which weakly pin it in place. The dissolution is exothermic overall, so cooling shifts the equilibrium towards the dissolved form [1].
