Figure 27. Temperature and salinity variations versus time in hours for < 

 variations were observed on anchor stations 1 and 3 but are not shown. 



as opposed to earlier variations of over 8.0 "/on in the same depth 

 interval. The increase in surface salinity and the resulting salinity 

 uniformity in the upper 8 meters were attributed to wind mixing 

 of relatively low salinity surface water with higher salinity water 

 from below. 



Observed winds for the period were from a nearly constant 

 direction of 240° to 270** True and a nearly constant speed of 6 m/sec 

 until cast 40 when a wind speed of 14 m/sec was observed; by station 

 42, winds were as high as 18 m/sec. 



Clearly defined periodicity is not immediately evident in 

 temperature and salinity variations observed on the three anchor 

 stations occupied. If tidal effects were present at these stations
