Psu salinity unit

WebWhat is salinity? Absolute (or ideal) salinity is the mass fraction of salts in seawater 1.In practical terms, salinity is expressed as PSU (practical salinity units) which are based on water temperature and conductivity measurements 1. Salinity used to be expressed in parts per thousand (ppt). For oceanic seawater, ppt and PSU are very close. Salinity of … WebThe salinity of seawater is on average 35 psu, i.e. about 35 g/kg. Salinity is one of the physical-chemical properties of water. Salinity measures the concentration of dissolved salts in water ( sodium chloride, magnesium chloride, magnesium sulphate etc.) using its electric conductivity.
