TEOS-10 Seawater Density

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.

CALCULATOR : TEOS-10 Seawater Density From Pressure Temperature And Practical Salinity [FREE] ±

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

Practical salinity = parts per thousand of dissolved solids (mainly salt). The absolute salinity is taken as 35.16504 / 35 times the practical salinity. The absolute salinity anomaly δSA is ignored.

Tool Input

T : Seawater Temperature
P : Seawater Pressure

Tool Output

ρ : Seawater Density

CALCULATOR : TEOS-10 Seawater Density At Atmospheric Pressure [FREE] ±
