large. Transport calculations were then made 

 for the lines of stations and the most interest- 

 ing result of those calculations was the net 

 southward transport of 0.1 Sv (Sverdrup = 

 lO^mYsec) through section G-G'. This section 

 was occupied during a period of average wind 

 speed of 18 knui» from the north. A southerly 

 transport had been observed in this area only 

 once before, in July 1967, aboard the CGC 

 NORTHWIND. The net transport through sec- 

 tion D-D' and C-C, 1.6 Sv to the north, showed 

 good correlation with the net transport through 

 section H-H', 1.7 Sv to the north. The current 

 regime in the Bering Strait showed the usual 

 summer conditions of greatest flow in the 

 eastern half of the Strait. The highest speed, 

 180 cm/sec (3.6 knots), was measured in the 

 lower layer at station 56 (figs. 19 and 20). 

 There was good correlation between the net 



transport through the four southernmost sec- 

 tions computed from the current meter data 

 and the average wind components normal to 

 each section. However, Grider stated that the 

 wind probably does not have a casual effect on 

 the change in net transport, but is more symp- 

 tomatic of atmospheric pressure zones which 

 exert pressure differentials on the sea surface 

 over a large distance. 



Dissolved Oxyjjen Distribution 



Measurements of dissolved oxygen concentra- 

 tions revealed that the surface layer in the 

 entire survey area was supersaturated or nearly 

 supersaturated with oxygen at the tempera- 

 tures which were observed. The Modified Shelf 

 Water and Deep Shelf Water masses were 

 about 90 '^'(' saturated, indicating recent contact 

 with the surface and low oxygen utilization.
