Boston Lightship (fig. 4, table 4)--Surface 

 water temperatures at Boston are somewhat 

 puzzling in that they do not parallel conditions 

 seen at Portland. Winter, spring, and early 

 summer temperatures were above the mean, 

 July below (as at Portland) and August- 

 September again above. The maximum, how- 

 ever, was the second lowest for the 5-year 



period 1956-60. Bottom water tennperati; 

 were in no way unusual. 



Surface salinity in May and June was 

 lowest on record and occurred slightly 1;
