Lake Superior is a large, deep, and cold freshwater lake that experiences a seasonal pattern known as turnover. During turnover, the surface waters, which have become oxygen-rich during the summer due to photosynthesis, cool and become denser in the fall.

In contrast, the other options (A, C, and D) do not have the same characteristics that would promote seasonal sinking of oxygen-rich surface waters.
