EXPLANATION OP OCEAN TEMPERATURE CHART No. 8. 



CAPE LOOKOUT J^IGHT-HOUSE, NOETH CAROLINA. 

 Observe}-: Denard Rujilet. 



Location of station. — Cape Lookout ligM-liouse is situated on the easterly sLorc, facing tlio open ocean, about 3 

 miles north of the extremity of Cape Lookout, North Carolina, and is about 90 miles northeasterly from Frying Pan 

 Shoals light-ship. The sandy shore slopes gradually for about half a mile before a depth of 3 fathotas is reached. 

 The 10-fathom curve is distant about 5 miles, the SO-fathom curve 21 miles, and the 100-fathom curve 35 miles. 



Geographical position.— IjatitndB, 34° 37' (20") N. ; longitude, 7G° 31' (26") W. 



Depth of water. — One foot. 



Eange of temperature.— Ah; 41° (43° to 84°) ; surface, 42° (42° to 84°). 



The curves of air temperature correspond more or less closely with those of the three preceding stations ; the range 

 is precisely the same, and the maximum and minimum records are each but 1 degree lower than at Frying Pan 

 Shoals. It will be observed, however, that the snrface curves agree in nearly all their details with those of the air, 

 having essentially the same range, and being much more irregular than at the three preceding light-ships. This is 

 due to the fact that the obseevations were made in shallow water, close inshore, on a very gradually sloping beach. 



Tahle sliowing the clireclion of the winds, iy qnaSrants, for each month of the year, Jiang the means of five years' oisenations.
