Salinity is the salt content, amount of salt dissolved in a volume of water evaporation and precipitation are both process which effect the volume of water they do. Salt evaporation ponds are filled from the ocean and salt crystals can be harvested as the water dries up sometimes these ponds have vivid colours. This can be attributed to lower evaporation rates and the melting of ice that dilutes seawater measuring changes in salinity, or salt concentration.
