The International Thermodynamic Equation Of Seawater – 2010 (TEOS-10): Implications for observational oceanography and ocean modelling

SCOR/IAPSO Working Group 127 has prepared a new Thermodynamic Equation of Seawater 2010 (TEOS-10 for short), and this has been adopted by IAPWS and IOC as the new thermodynamic description of seawater for both engineering and oceanographic research purposes. This thermodynamic description of seawater provides accurate algorithms for density, entropy, enthalpy and many other properties. The talk will concentrate on three main topics, namely (i) the definition and use of a new form of salinity called Absolute Salinity which takes into account the spatial variation in the composition of seawater, (ii) a thermodynamic variable that can be used to accurately represent the transport and mixing of “heat” in the ocean, and (iii) the differences between the specific volume of TEOS-10 and that of EOS-80 (the International Equation of State of seawater that has been in use since 1980). The talk will discuss the relative improvements in the accuracy of observational oceanography and ocean models that can be expected from adopting TEOS-10.
