HYDROGRAPHIC STATION DATA 



All hydrographic station data obtained in the Gulf Stream, consisting of 

 precise temperature and salinity measurements, have been pubUshed at 

 Copenhagen since 1910 by the Conseil permanent international pour 

 I'exploration de la mer in its annual Bulletin hydrographique, for the period 

 beginning uith the year 1908. Because of the great care taken in editing 

 the Bulletin, there is an interval of about five years between the date of 

 observation and the date of publication. 



A complete index, including charts, of all the hydrographic data from 

 the Atlantic Ocean prior to 1932 is contained in International Aspects of 

 Oceanography, by T. Wayland Vaughan (1937). 



Two papers by C. O'D. Iselin (1936, 1940) may be used as an index for 

 Atlantis stations made in the Gulf Stream between 1930 and 1940; the 

 original data are to be found in Bulletin hydrographique. 



Since the Second World War there have been relatively few hydro- 

 graphic sections of the Gulf Stream ; specifically : 



1946, Sept. Atlantis stations 4414-4423 (no salinities), a Chesa- 

 peake Bay-Bermuda section. 



1947, June. Atlantis stations 4565-4570, a section off Cape 

 Hatteras. 



1947, Dec. Atlantis stations 4623-4627, a section along 65° W. 



longitude. 

 1949, July-Sept. Atlantis stations 4760-4832, an areal survey 



near the Grand Banks.
