EXPLANATION OP OCEAN TEMPERATURE CHART No. 11. 



FIVE-FATHOM BANK LIGHT-SHIP, NEW JEKSEY. 

 Observers: John Reeves, Daniel Manlove, William W. Smith. 



Location of station .—Th'xs light-ship is located about 14 miles from the nearest part of the New Jersej' coast, just 

 east of Cape Mny, north of the entrance to Delaware Bay, and about 56 miles northeasterly from Winter-Quarter 

 Sboal light-ship. It is anchored about IJ miles outside of the 10-falbom curve, in a depth of Vi fatlioms. The 20- 

 fathom curve is distant 13^ miles, the 100-fathora curve 55 miles. 



(icographical ^josi/ioH.— Latitude, 38° 48' (25") N. ; longitude, 74" 3!i' (09") W. 



Depth of water. — Twelve fathoms. 



Range of temperature (March 1 to January 1).— Air, 47° (:J6°.5 to 83°.5) ; surface, 39° (37° to 7G°). 



The temperatures at this station differ somewhat from those at Winter-Quarter Shoal, and not constantly in the 

 same direction, being sometimes slightly higher, at others slightly lower, during corresponding periods. With a 

 single marked exception, the summer air temperatures average lower here ; the surface curves are more nearly like 

 tbo.se at Winter Quarter, but do not sliow so low a minimum in the colder months plotted. An unusually high air 

 temperature was reached between June 19 and 29, 1882, accompanied mainly by southwesterly winds, which are tlie 

 prevailing winds for that month. This extreme variation is not observable at tlie neighboring stations, and it ap- 

 parently had no inlluenco upon the temperature of the water at this place.
