BIGELOW: EXPLORATIONS OF THE COAST WATERS.

Station (10249). Throughout the deeper parts of the Gulf the vertical 

 range of salinity was considerable, the general type of vertical dis- 

 tribution, for its northern half, agreeing so closely with that of past 

 years, that it is not necessary to reproduce the curves. And we again 

 found the decrease in vertical range, passing northeast from Cape 

 Ann, with which we are familiar (1914a, 1915).

In the southeastern corner of the Gulf (Station 10225), new ground 

 for us, salinity increased very rapidly with increase of depth, to about 

 35%o at 140 meters (Fig. 19), a higher reading than has ever been 

 recorded before for any part of the Gulf; below that depth it was 

 practically uniform down to the bottom, in 250 meters. And the 

 salinity curve for the Eastern Channel (Station 10227) is of the same 

 type.
