Clearly defined periodicity was not evident in observed temperature 

 and salinity variations. 



Seven current observations made at anchor station 1 suggest 

 an easterly-southeasterly surface flow of less than 3 to 20 cm/sec 

 in Long Strait at the time of the survey. A west-northwesterly 

 flow of 5 to 20 cm/sec was observed near the bottom. 



Seventeen observations made on anchor station 2 also suggest 

 an easterly-southeasterly flow of 5 to 25 cm/sec at the surface 

 and a northwesterly flow of 5 to 15 cm/sec near the bottom. 



Fourteen observations made on anchor station 4 suggest a northerly 

 surface flow of 5 to 30 cm/sec near the mouth of the Kolyma River. 

 Near the bottom at 15 meters, a southwesterly flow of less than 

 5 cm/sec was observed. 



Dissolved oxygen supersaturation relative to equilibrium sea 

 surface oxygen solubility was observed in the East Siberian Sea 

 during the summers of 1963 and 1964, Observed dissolved oxygen 

 values generally increased seaward from the Siberian mainland and 

 toward the eastern regions of the sea in 1963. Supersaturation 

 usually was limited to the upper 25 meters in the eastern East Siberian 

 Sea and the upper 15 meters in the sea's shallower western regions. 



Observed supersaturation most likely can be attributed to photosynthesis, 

 as was the case in the Laptev Sea.
