Direct density measurements are also used to estimate salinities, particularly in highly saline lakes. [4] Sometimes density at a specific temperature is used as a proxy for salinity. At other times an empirical salinity/density relationship developed for a particular body of water is used to estimate the salinity of samples from a measured ...
The thermal conductivity decreases with increasing salinity and increases with increasing temperature. [ 6 ] [ 7 ] The salt content can be determined with a salinometer . Density ρ of brine at various concentrations and temperatures from 200 to 575 °C (392 to 1,067 °F) can be approximated with a linear equation: [ 8 ]
Near 0 °Bé would be approximately the density of water. −100 °Bé (specific gravity, 0.615) would be among the lightest fluids known, such as liquid butane . Thus, the system could be understood as representing a practical spectrum of the density of liquids between −100 and 100, with values near 0 being the approximate density of water.

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.
The difference between the EOS and TEOS-10 is that in TEOS-10, salinity is stated as absolute salinity, while in the previous EOS version salinity was stated as conductivity-based salinity. The absolute salinity is based on density, where it uses the mass off all non-H 2 O molecules. Conductivity-based salinity is calculated directly from ...
