Prior to 1978, salinity or halinity was expressed as ‰ usually based on the electrical conductivity ratio of the sample to "Copenhagen water", an artificial sea water manufactured to serve as a world "standard".
Salinity is an ecological factor of considerable import, influencing the types of organisms that live in a body of water.
In oceanography, it has been traditional to express salinity not as percent, but as concentration in parts per thousand (ppt or ‰;), which is grams of salt per liter of water.
It has always been the case that to get a precise salinity and then convert this to an amount of a substance (sodium chloride, for instance) required knowing much more about the sample and the measurement than just the weight of the solids upon evaporation (one method of determining salinity).
Highly salinewater, from which salts are or are about to crystallize out of, is referred to as brine.
