TEOS-10 Seawater Property Modules

Calculate TEOS-10 seawater density from temperature, pressure and practical salinity.

The hydrostatic pressure used in TEOS-10 can be calculated from water depth or relative elevation. The water density is assumed constant. Changes in water density with water depth, salinity and temperature are ignored. Elevation is measured relative to an arbitrary datum (+ve up -ve down). Mean sea level (MSL) is often used as a datum.

Calculate TEOS-10 seawater practical salinity from pressure, temperature and conductivity.

Practical salinity is measured by comparing the sea water conductivity with a reference conductivity.

To convert pressure: 1 MPa = 100 dbar (deci bars) or 1 dbar = 1e4 Pa. To convert conductivity 1 S/m = 10 mS/cm.

Calculate TEOS-10 seawater vapour pressure from temperature, and practical salinity.

Seawater vapour pressure is calculated from fresh water vapour pressure using the equation from Sharqawy (2010). The fresh water vapour pressure is calculated from temperature using the IAPWS R7-97 steam equations. Practical salinity = parts per thousand of dissolved solids (mainly salt). The absolute salinity is taken as 35.16504 / 35 times the practical salinity (absolute salinity equals reference salinity). The absolute salinity anomaly δSA is ignored.
