When the animation starts, the temperature of the water cube is very low. At low temperatures the molecules move slowly, and a lot of oxygen can be dissolved into the water. As the animation progresses, the temperature of the water increases. With increasing temperature the molecules' movement increases, and most of the oxygen escapes into the atmosphere. Just knowing the temperature of the water in an estuary can give us a pretty good idea of how healthy it is. One important thing we can tell from water temperature is how much oxygen can be dissolved into the water. Dissolved oxygen is critical for the survival of animals and plants that live in the water.
