S U M M A R YThis comment discusses the analysis of magnetotelluric data from the Corinth Gulf area carried out by Pham et al. It is shown that a consistent analysis should include the conducting sea water of the Gulf, which has a longitudinal conductance of about 2000 S. This was overlooked in the above study. The magnitude of the sea-water effect is demonstrated by 2-D modelling and new induction vector data.

Extensive EM studies have been made in the Ukraine during the last 40 years and a set of reliable results have been received. Data from 3000 Magnetotelluric soundings are presented as maps of effective apparent resistivity at periods of 150 s and 500 s and impedance phase at T = 150 s. The principal results are: S1 map at the scale 1:2500000, tracing and study of Carpathian, Kirovograd and Donbas regional conductivity anomalies, a map of the crustal conductivity for Ukrainian Shield, a study of faults.
