The effect would be to reverse the sign of ei (meas- 

 ured potential) and give the impression that experi- 

 mental observations disagree even quantitatively 

 with theory. 



Potentials measured by the electrodes moored 

 near shore in the eastern Bering Strait generally in- 

 dicate polarities opposite to that expected from the 

 known direction of water flowing through the system 

 and would lend experimental support to the con- 

 clusion that water motion seaward of a moored elec- 

 trode system can have an overriding effect on the 

 potentials recorded. 



Because of the many indeterminate effects con- 

 tributing to the potentials measured at the Field 

 Station, the electrode system was calibrated from 

 current survey data and an emperical relationship 

 used to convert observed potentials to volume trans- 

 port values. 



The relation between hourly potentials from the 

 sea electrode system and volume transport for a 

 25-mile section of the eastern Bering Strait (calcu- 

 lated from the 1 August 1954 current measurements) 

 is indicated in figure 7. The displacement from zero 

 may be attributed to several possibilities: (1) elec- 

 trode polarization, (2) concentration efFects, (3) earth 

 currents, and (4) water motion in the western Bering 

 Strait. Further current studies and comparison with 

 simultaneous potential measurements ore required to 

 determine the constancy of the displacement and to 

 provide an accurate estimate of cause. 



Using the relation in figure 7, average monthly 

 transports through a 25-mile sector of the eastern 

 Bering Strait were computed from potentials recorded 

 on the sea electrode system. The potentials were 

 computed by determining a mean value from the
