摘要

The Aral Sea is an important water area both for monitoring and oceanological studies, because its salinity and salt composition strongly differ from the oceanic. We offer a semiempiric calculation method of electric conductivity and the coefficient of its temperature dependence k judging from the ionic composition of water. The properties of the solution are considered as the sum of properties of seven binary salts taken based on the ionic composition of the solution. The MgSO4 concentration is thought to be the highest possible, which makes the salt concentration nearly unambiguous. In a salinity range of 46-120 and temperature range of 5-25 degrees C (2002-2009), the standard deviation of the calculated and measured electric conductivity was 2.9. To refine the calculation of salinity from electric conductivity measurements using the "oceanic" formula, we suggest its preliminary reduction to a constant temperature (20 degrees C) using the measured or calculated coefficient k.
