Short summary
A new density–salinity relation of standard seawater was developed based on highly accurate density measurements. The comparison of densities calculated using the new relation with those using the reference equation of state TEOS-10 showed significant deviations that are likely caused by accuracy overestimations of some density data underlying TEOS-10 and EOS-80. The new relation enables the determination of seawater density from salinity and vice versa with unprecedented accuracy.
