Frying Pan Shoals Lightship (fig. 18, table 

 18)--The cold surface water of late February 

 and March probably represents a flow of 

 coastal water southward past Cape Hatteras, 

 as occurred in 1958. Not until June did 



temperatures reach the mean again. The bot- 

 tom maximum in early September of 81.8° F. 

 equaled the 1958 high. The intrusion of colder 

 water near the bottom in summer is an annual 

 phenomenon.
