What is Salinity?

There are two types of salinity, absolute salinity and practical salinity.

There are two types of salinity, absolute salinity and practical salinity.

• Absolute salinity is a ratio between the mass of dissolved material in seawater and the mass of the seawater.
• Practical salinity is the ratio of the electrical conductivity of a seawater sample to that of a standard potassium chloride (KCl) solution at the same temperature and pressure.
