The USGS salinity scale defines three levels of saline water. The salt concentration in slightly saline water is 1,000 to 3,000 ppm (0.1–0.3%); in moderately saline water is 3,000 to 10,000 ppm (0.3–1%); and in highly saline water is 10,000 to 35,000 ppm (1–3.5%).

Salinity (/ s ə ˈ l ɪ n ɪ t i /) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰).
The density ratio of a column of seawater is a measure of the relative contributions of temperature and salinity in determining the density gradient. [1] At a density ratio of 1, temperature and salinity are said to be compensated : their density signatures cancel, leaving a density gradient of zero.
A shallow and wide pool will evaporate at a greater rate than a pool of the same volume of water which is deeper and has a smaller surface area. Evaporation rate also affects salinity, the higher the evaporation rate the higher the salinity, with rates as high as a third greater than ocean water.
internal energy and entropy of liquid water at the solid-liquid-gas triple point are zero, entropy and enthalpy of seawater are zero at S A (Absolute Salinity) = 35.16504 g/kg, T (Temperature) = 273.15 K, p (pressure) = 101325 Pa, entropy and enthalpy of dry air are zero at T (Temperature) = 273.15 K, p (pressure) = 101325 Pa.

Sigma-t is a quantity used in oceanography to measure the density of seawater at a given temperature. [1] σ T is defined as ρ(S,T)-1000 kg m −3, where ρ(S,T) is the density of a sample of seawater at temperature T and salinity S, measured in kg m −3, at standard atmospheric pressure.
This is a list of bodies of water by salinity that is limited to natural bodies of water that have a stable salinity above 0.05%, at or below which water is considered fresh. Water salinity often varies by location and season, particularly with hypersaline lakes in arid areas, so the salinity figures in the table below should be interpreted as ...
