Solution

When the atmospheric temperature goes below $0^{\circ}$ C, the water at the surface gradually freezes to ice, but the water under the ice layer remains at 4 $^{\circ}$ C. The ice has little passageways to let air in and out. Hence, the oxygen gets dissolved and other gases are pushed out.
