The amount of dissolved salts that are present.

Salinity

Salinity is the measure of all the salts dissolved in water. Salinity is usually measured in parts per thousand (ppt). The average ocean salinity is 35 ppt and the average river water salinity is 0.5 ppt or less. This means that in every kilogram (1000 grams) of seawater, 35 grams are salt.
