Photographer's Note

Whenever I am down at the coast I like to drive out to the Walvis Bay salt pans. Apart from the incedible wet-land bird life the flat desolate-looking landscape of the pans fascinates me.

Walvis Bay has one of the largest salt works in Africa. The seawater is fed into large ponds, which gradually dry out through natural evaporation. The colour indicates the salinity of the ponds. Micro-organisms change their hues as the salinity of the pond increases. In low to mid-salinity ponds, green algae are predominant. In middle to high salinity ponds, an algae called Dunaliella salina shifts the colour to red. The salt fields of Walvis Bay cover an area of 3 500 hectares and annually produce 400 000 tons of high-quality salt. This successful commercial enterprise also provides an ideal habitat for many species of marine birds.
