EXPLANATION OF OCEAN TEMPERATURE CHART No. 7. 



FRYING PAN SHOALS LIGHT-SHIP, NORTH CAROLINA. 



Observers: D. W. Manson, W. R. Walker, J. H. Dosher.J. D. Davis, G. D. Walker, H. Swax. 



Position. — Fiyiug Pan Shoals light-sbip is located about 6J miles from the outer extremity of the main part of 

 Frying Pan Shoals, about 17 miles .southeasterly from Caiie Fear, North Carolina, and about 108 miles northeasterly 

 from Rattlesnake Sboal light-.sbip. Within a radius of 3 miles on all sides depths of 6i to 11 fathoms occur. The 20- 

 fathom curve is distant 21 miles, the 100-fathom curve 36 miles. 



Geographical ^wsiJioH.— Latitude, 33° 35' (00") N. ; longitude, 77° 50' (04") W. 



Depth of waUr. — Ten to 11 fathoms. 



Range of temperature.— Ah; 41° (44° to 85°) ; surface, 33° (49°.5 to 82°. 5). 



The curves of air temperature do not diH'cr essentially from those of the two' preceding stations; the range of 

 temperature is precisely the same, although the maximum and minimum records are each 1|° lower at this station. 

 The surface temperatures, however, have a more limited range by 5°, reaching neither the same maximum nor mini- 

 mum as at Rattlesnake Slioal.
