CONCLUSIONS 



1. Average mass water transport through the 

 eastern Bering Strait exhibits considerable fluctua- 

 tion throughout the year both in volume and direc- 

 tion. 



2. A northerly volume transport varying from 

 0.8 to 3.1 X 10'" cubic meters per second appears 

 characteristic of the period August through No- 

 vember. 



3. An area of maximum current velocities is 

 indicated in the 8-to-12-mile section of the eastern 

 Bering Strait. 



4. Potentials measured v/ith short sea electrode 

 systems can be correlated with mass water transport, 

 while land electrode systems appear generally un- 

 workable for the Cape Prince of Wales area. 



5. Bottom sea water temperatures in the eastern 

 Bering Strait attain maximum average values of 45°F 

 to 49° F by late August and reflect north-south shifts 

 in wind direction and water transport. 



6. Omitting initial freeze-up discontinuities, the 

 logarithm of accumulated degree days below 29°F 

 exhibits essentially a linear relationship with fast 

 ice accretion at Wales, Alaska. 



7. Average total ice growth at Wales is 46 

 to 48 inches, with first slush ice formed late October 

 to early November and fast ice break-up normally 

 completed by mid June. 



8. Tides off Wales are semi-diurnal in varia- 

 tion, with ranges between high and low water during 

 the summer months averaging less than 12 inches. 



RECOMMENDATIONS 



1. Extend and make simultaneous oceano- 

 graphic and meteorological measurements essential 

 to a detailed analysis of the sea-ice-heat-budget 

 regime. 



2. Continue measurement of average water 

 transport through the Bering Strait by the electro- 

 magnetic method and conduct independent water 

 velocity measurements for correlation with transport 

 data. 



3. Conduct daily sea-water temperature meas- 

 urements from strategic points along the northwestern 

 Alaskan coast as on aid to the study of temperature/ 

 transport discrepancies. 



4. Conduct sonar studies in respect to the effect 

 of ice coverage and movement on ambient noise 

 and passive detection ranges. 



5. Study and relate tide and wind contribution 

 to water transport through the Bering Strait. 



6. Obtain data on the variation of the hori- 

 zontal component of the earth's magnetic field and 

 the contribution to the fluctuations present in the 

 water-transport-generated signal potentials. 



7. Conduct laboratory experiments to simulate 

 the effect of varying current speeds and direction 

 on electrical potentials generated by simultaneous 

 irregular flow conditions across the Bering Strait.
