The Density of Seawater: Some Practical Relationships.

reportActive / Technical Report | Accession Number: ADA088277 | Open PDF

Abstract:

Traditionally, the density of seawater as a function of temperature and salinity at atmospheric pressure has been discussed in terms of the density function, Sigma-T, and, in this report, some simplified mathematical relationships are presented from which changes in Sigma-T can be predicted from changes in temperature and salinity. However, density is also affected by pressure and an accurate treatment of the density of seawater within a deep ocean water mass requires a more sophisticated approach. An outline of one such treatment and the results obtained from it are given in detail. Author
