A comparison of the temperature coefficients of electrical conductivity of Atlantic and Pacific seawaters

The Practical Salinity Scale 1978 (PSS) defines the relationship among salinity, electrical conductivity, temperature, and pressure. Strictly speaking, the PSS is only applicable to waters with the same relative chemical composition as standard seawater. We have tested the predictions of the PSS for samples of Atlantic and Pacific waters. The results indicate that the PSS is valid for these natural seawaters over the defined temperature range of the scale.
