Sea salt is produced by the natural evaporation of seawater in natural lagoons or artificial basins. With the help of the sun and wind, the water in the flat basins evaporates and the salt concentration gradually rises. Steadily increasing in concentration, the water is pumped into several pools, until it finally reaches the “harvesting pool”, where the sea salt crystallizes and is scooped from the water.
From ocean to ocean
3.5% of seawater consists of dissolved salts. Though that is only an average: Whereas the salt concentration in cooler oceans or in sea basins with an influx of freshwater is lower, the salt content in areas that experience greater evaporation is significantly higher.
