Namibia’s Coastal Desert is one of the oldest deserts in the world. Its sand dunes, created by the strong onshore winds, are the highest in the world. Because of the location of the shoreline — at the point where the Atlantic’s cold water reaches Africa — there is often extremely dense fog. Near the coast there are areas where the dunes are vegetated with hammocks. Namibia has rich coastal and marine resources that remain largely unexplored.
The sea can turn to foam in any part of the world, but this most often occurs in the southern hemisphere. Within a few minutes, the entire coast, houses and chairs disappear in suddenly appearing foam that slowly dissolves in the sand. For foam to occur in seawater, a large amount of algae, salt and some waste must accumulate.
