8 EXPLORATIONS, WESTERN ATLANTIC, STEAMER BACHE, 1914. 



Schott's (1902) chart of average surface salinity for the year shows 

 the same northward tongue of 36.5*^/00 or Antilles water, as is to be 

 seen on the Baclie chart (fig. 2) ; but most of the critical area is 

 blank for want of data. The records since collected by the inter- 

 national committee for the exploration of the sea (1909, 1910, 

 1911) add very little to our knowledge of the region in question, 

 those for this general part of the Atlantic being chiefly limited to a 

 line from the neighborhood of Bermuda to Jamaica. In short, pre- 

 vious salinity records, at least by modern methods, are so scanty for

the region crossed by the Baclie that it is impossible to state whether 

 the conditions which she encountered there are characteristic of the 

 winter season. 



Typical examples of the serial temperatures and salinities taken by 

 the Baclie between the continental slope and Bermuda, and between 

 Bermuda and the Bahama Bank, which are given in full in the tables 

 (p. 55), are represented graphically in the accompanying sections 

 (fig. 3-10). The temperatures all agree in showing a general cool- 

 ing from 19°-22° on the surface to about 4° at 1,800 meters. The
