Abstract

We find out if the ratio of cross-strait voltage to water transport for the Bering Strait (BS) is constant. For this purpose, we have developed a technique to construct BS water velocity maps. We have built up a three-dimensional conductivity model for the BS region. Using this model, we have simulated coast-to-coast voltage for the various velocity maps constructed. We have found that the voltage/transport ratio remains constant for electromagnetic field periods exceeding 2 days. We have estimated the ratio as 239 ± 11 mV/(km2 · m/s) assuming bottom sediment conductance to be 600 S. We conclude that measuring cross-strait voltage allows the monitoring of BS water transport.
