What is Salt evaporation pond?
A '''Salt evaporation pond''' (or '''saltern pond''') is a man-made [[shallow]] [[pond]]. Usually it is located near the [[sea]]. The ponds can be filled with [[salt water]]. The water is then left to [[evaporation|evaporate]]. The [[salt]] is left behind, and can be harvested. Such ponds also provide a [[habitat]] for several kinds of [[animal]]s. Most of these animals are [[bird]]s. The color tells how much salt there is left in the water. Green colors come from special [[alga]]e. These algae are there in low to mid [[salinity]] ponds (ponds with little salt in the water). In middle to high salinity ponds, an alga called [[Dunaliella salina]] shifts the color to red. Millions of tiny [[brine]] [[shrimp]] create an orange cast in mid-salinity ponds. Other bacteria such as [[Stichococcus]] also contribute [[tint]]s. These colors are especially interesting to [[airplane]] passengers or [[astronauts]] passing above due to their somewhat artistic formations of shape and color. <gallery> Image:Salz 01.JPG|Ponds on the [[Ile de Ré]] in [[France]].
