Abstract: The 41st Executive Council of the IOC instructed the Executive Secretary to present to the Assembly, at its 25th session, the new equation of state of seawater that has been developmed by SCOR-IAPSO working group 127 and to invite the Assembly to consider adopting a resolution formally adopting this new standard. One of the implications of the new formulation is adoption of a new variable ‘Absolute Salinity’. There are substantial potential implications associated with adopting the new standard for long term continuity of records and national data centers. WG127 has recommended the adoption of Absolute Salinity to be used in journals to describe the salinity of seawater and to be used as the salinity argument to algorithms that give the various thermodynamic properties of seawater. This recommendation deviates from the current practice of working with Practical Salinity and typically treating it as the best estimate of Absolute Salinity. At the same time, the WG strongly recommend that the salinity that is reported to national oceanographic data centers remain Practical Salinity as determined on the Practical Salinity Scale of 1978 (suitably updated to ITS-90 temperatures).
