Figure 28. Temperature and salinity variations versus time in hours for anchor station 4. A plot of 

 wind speed versus time is also included . Note the effects of increased v/ind speed on observed temp- 

 erature and salinity in the upper eight meters on casts 41 and 42. 



they appear to have been obscured by local factors such as wind 

 mixing, ice melt, or the influx of river runoff. 



Sustained winds of 18 m/sec for a 12-hour period were effective 

 in achieving near isohaline conditions down to 8 meters on station 

 42 during mid-September 1964. Wind mixing below 8 meters was not 

 evident during station occupation.
