Service Description: This map of estuarine salinity zones is based on analysis of long-term salinity data for 37 Gulf of Mexico estuaries. Each estuary was subdivided into three possible salinity zones between the head of tide and the seaward boundaries, based on annual-averaged and depth-averaged salinities. The three zones include a Tidal Fresh Zone (0 - 0.5 parts per thousand), a Mixing Zone (0.5 - 25 parts per thousand) , and a Seawater Zone (25 parts per thousand or greater).
