At the southern tip of South America, at Cape Horn, there is a notable separation between the waters of the Pacific Ocean and those of the Atlantic Ocean, even though both are salty. This difference is caused by a freshwater river that originates from the melting of glaciers in Antarctica. This flow of fresh water, with a significantly lower density, creates a barrier that prevents complete mixing of the ocean waters, resulting in a visible line in the water that changes from green to blue.
