Boston Lightship (fig. 4, table 4) 



The cold year is apparent in the temperatures of air and 

 surface water at this observation post also. The surface water 

 temperatures clearly reflect the monthly air temperature which was 

 above normal only in May and December and was near normal for June. 

 New record lows were established in 16 of the 33 decads in which 

 surface water temperature was reported. 



Bottom water temperatures were record lows in all decads 

 reported except for late April through mid -June. In that period 

 the surface water temperature was above normal and the thermocline 

 was forming. 



The surface salinity minimum came in early June, 2 decads 

 later than normal. Salinities were above normal from mid -April through 

 the end of the year but did not exceed the records established in the 

 drought year of 1957.
