Figure 13 illustrates the interpreted distribution of the 

 32 and 33 '^no isohalines at depths of 5, 10, 15, and 20 meters. Surface 

 salinities for this region ranged from less than 10 to 26"^^^ but 

 are not shown, even though they illustrate the same localized distribution. 

 Figure 14 presents three cross-sections drawn from stations occupied 

 in this area. 



3. Dissolved Oxygen Distribution . Conditions of dissolved 

 oxygen supersaturation relative to equilibrium sea surface solubility 

 were observed in the Laptev Sea during August and September 1963. 

 Dissolved oxygen values as high as 9.97 ml/1 were noted at 12 meters 

 on station 150. Using Carpenter's saturation values, which are 

 corrected to 75 mm total pressure, including water vapor, this figure 

 yields a dissolved oxygen saturation in excess of 115% (Carpenter, 

 1966). 



Oxygen saturation values generally were lower in the vicinity 

 of the Lena River plume, and supersaturation was noted there to a
