What is the salinity of the Atlantic ocean?
The salinity of the Atlantic Ocean varies according to depth and location. The highest salinity values are found in surface waters at 20-30 degrees north and south of the equator, where evaporation is high and precipitation is low. These values reach a maximum of 37.3 parts per thousand (ppt) in the Atlantic Ocean. The lowest salinity values are found towards the poles, where evaporation is low and freshwater inputs from melting ice and precipitation are high. The lowest salinity in the Atlantic is approximately 34.2 ppt in surface waters. Deep ocean waters are much less variable in salinity, since they are not subject to evaporation or direct freshwater inputs. Below 1000 m, the salinity is between 34.5 and 35.0 ppt at all latitudes.
