Barnegat Lightship (fig. 13, table 13)-- 

 Except for below normal surface temperatures 

 in March and again in December, 1960 was a 

 warm year at stations between Barnegat and 

 Cape Hatteras. Temperatures, surface and 

 bottom, in January and February were above 

 those of the 1956-59 period; in terms of 

 10-day means the bottom maximum of 68 F. 

 in mid-September was the highest so far 

 recorded for the Barnegat station. The highest 



daily reading was 69.9 F. on September 14 

 after the passage of hurricane Donna. This 

 was the only position where that storm com- 

 pletely mixed the water column. Autumn chil- 

 ling was normal until mid-December, when 

 it was accelerated. The salinity minimum in 

 late May was the lowest for the 5-year period 

 1956-60. Only a trace of the expected summer 

 intrusion of cold water along the bottom is 

 apparent in the isotherms.
