just north of Cape Ann (Station 10103), and close to the coast of j 
Maine east of Mt. Desert (Station 10098); saltest in the centre of the 
Gulf and over the eastern basin (Stations 10092, 10093, and 10100), 
and over the edge of the Nova Scotian slope (Stations 10094, and 
10096). And this is further illustrated by the following table of the 
mean salinity of the upper 50 fathoms :—

Salinity on the bottom. The bottom salinity of the Gulf (Fig. 36) 
depended chiefly on depth, the bottom water of the basins being from 
34%o to 34.27%. The bottom salinity of the coastal zone surrounding 
the whole Gulf was below 33%  (32.5%0-32.9% 0), the curve of 33%o 
agreeing, roughly, with the fifty fathom contour of the bottom. But — 
there were various local anomalies, already pointed out, especially 
the abnormally low bottom salinities of the several circumscribed 
sinks on the western side of the Gulf. 
Salinity profiles. The profile from Massachusetts Bay to German 
Bank (Fig. 48, Stations 10106, 10087, 10088, 10090, 10092, 10095, 
10094, 10095), shows that the water was salter in general, depth for 
1 Mean for 40 fathoms. 2 Mean for 30 fathoms. ‘
