The lowest salinities of all (3l9co~) like the lowest temperatures lay 

 close to the southern coast of Xova Scotia, water fresher than 329fo 

 spreading seaward, fanlike off Shelburne, with an apparent tendency 

 to swing around Cape Sable, contrasting with a salter tongue approach- 

 ing the land off Halifax. Attention should also be drawn to the fact 

 that surface salinities disclose an unmistakable fresh band, running 

 diagonally across Georges Bank, corresponding to the low tempera-

ture there. And the sharp contrast in salinity between coastal and 

 ocean water, illustrated by the sudden north-south rise in salinity 

 along the southern edge of Georges Bank, also deserves mention. 



Salinity Sections. — The water of the Gulf of Maine was freshest 

 on the surface, saltest on the bottom (Fig. 19), the only exception to 

 this rule being a slight decrease of salinity below 150 meters at one
