Buzzards Lightship 



(Figure 8, Table 6) 



Svirface water temperatures stayed substantially above the mean 

 for Vineyard Sound Lightship throxighout the year, and above those for 1956 

 until the first part of November, when the two became comparable. The 

 annual mean temperature of 52.3°F was higher than any for the period of 

 record (1879-1910) at Vineyard Sound Lightship, which was stationed less 

 than four miles away from the position of the present Buzzards Bay 

 Lightship, 



Ten day mean salinity values showed a high of 32,80 %•• in mid- 

 October and a low of only 32,07 %o in mid-April, This contrasted with a 

 1956 high of 32.36 %o and a low of 31. U2 %o. This difference reflects the 

 low precipitation and runoff of 1957.
