Salinity is the saltiness or amount of salt dissolved in a body of water, called saline water. It is usually measured in g/L or g/kg.

How is salinity defined?

Ocean salinity is generally defined as the salt concentration (e.g., Sodium and Chlorure) in sea water. It is measured in unit of PSU (Practical Salinity Unit), which is a unit based on the properties of sea water conductivity. It is equivalent to per thousand or (o/00) or to g/kg.

What is salinity in geography?

Salinity is defined as the ratio between the weight of the dissolved materials and the weight of the sample sea water. ... Evaporation is also controlled by salinity as it is lower over more saline water than over less saline water. Salinity also increases the density of sea water.
