Conservative Temperature
D1. Physical and chemical oceanography and marine meteorologyDefinition
TEOS-10 thermodynamic variable representing heat content per unit mass.
Conservative temperature is the TEOS-10 thermodynamic variable that represents the heat content of seawater per unit mass, proportional to potential enthalpy. It is conserved under mixing far more accurately than potential temperature, so it is the recommended variable for ocean modeling, heat-budget, and water-mass analysis under the 2010 standard. It is paired with Absolute Salinity rather than Practical Salinity.
