Short summary

The variability of the relative salt composition in seawater may have significant influence on physical properties. Based on off-shore and laboratory measurements, this effect is quantified for the first time for speed of sound in Baltic seawater. Time-of-flight sensors with sufficient resolution were applied to resolve the small sound speed anomaly to values in the range of several cm s⁻¹. The results suggest that the effect can be reasonably predicted by the recent equation of state (TEOS-10).
