Savannah Lightship (Figure 18, Table 18) 



Surface water temperatures were below the mean in January, 

 early February and late April; at other times they were near or 

 slightly above through mid-November. The summer maximum at 

 surface and bottom was higher than those of the three previous 

 years, and appeared in late August, some 20 days earlier than at 

 stations north of Cape Hatteras . 



Salinity at the Savannah station varies widely both seasonally 

 and from year to year since the lightship is close to numerous rivers 

 debouching to the north and west. The minimum in April reflects the 

 heavy rains experienced during March throughout the Southeast, when 

 monthly totals ranged up to 400 percent of normal in Florida.
