Salt evaporation pond

The salt pans are shallow and expansive, allowing sunlight to penetrate and reach the seawater.

[3] However, Ghanaian fisheries scientist RoseEmma Mamaa Entsua-Mensah also noted that salt winning can destroy mangrove forests and mudflats, altering the environment and making it unproductive for other development or fish growth.

This Gibbs Free Energy becomes positive when the salinity is high enough (or air humid enough) for the salt solution to cause water to condense into it.

Due to variable algal concentrations, vivid colors (from pale green to bright red) are created in the evaporation ponds.

Halobacteria, a type of halophilic Archaea (also known as Haloarchaea), are responsible for changing the color of middle to high-salinity ponds to shades of pink, red, and orange.

In time the sea water evaporated, leaving the salt behind on the post, where it was easier to harvest.
