EXPLANATION OF OCEAN TEMPERATURE CHART No. 14. 



FIRE ISLAND LIGHT-HOUSE, NEW YOEK. 

 Observers: C. A. Blydbnbuegh, Seth E. Hubbard. 



Location of station. — This ligbt-house is situated on the east side of Fire Island Inlet, south side of Long Island, 

 31 miles E. l>y N. from Sandy Hook light-ship ; and the observations were taken in the narrow entrance to Great 

 South Bay, between Fire Island and Oak Island. The 10-fathom curve is distant IJ miles from the outer beach; 

 the 20-fatlioni curve, 18 miles; the 100-fathom curve, 85 miles. 



Geographical position.— LsktitaAe, 40° 37' 57" N. ; longitude, 73° 13' 09" W. 



Bepth of water. — Three feet. 



Sange of temperature (March 1 to January 1).— Air, 480.5 (35° to 83°.5); surface, 40° (35° to 75°). 



The observations at this station were probably taken in rajiidly running water, as the surface curves are compar- 

 atively regular, and the maximum surface temperature is 8° lower than the maximum for the air. In the range of both 

 air and surface temx)eratures this station agrees most closely with Five-Fathom Bank, the differences being very slight.
