Diamond Shoal Lightship (fig. 13, table 13) 



Surface water temperatures generally were below normal early 

 in the year and above normal during the last 4 months. There were 

 record low temperatures in mid-February and late June and record highs 

 in mid-October and early November. Bottom temperatures were not ob- 

 served regularly during the year but record lows were established in 

 middle and late June. 



Surface salinity was low during most of the first half of the 

 year and high during most of the second half. Apparently coastal waters 

 predominated early in the year whereas Gulf Stream water was more 

 prevale nt in the latter half (cf. surface temperature).
