temperatures between 0-0° and 10° C, but farther downwards the tempera. uro 

 increases to about 4° C in 300 and 400m. The layers of water of temperatures below 

 zero, found especially in the spring, are not found during the autumn, but the inter- 

 mediate temperature minimum at a depth of 100 to 160m. indicates that idiMiiical 

 water-layers are still found there, but their temperature is increased during the 

 summer. 



Section XXIII, Stations 107-102 (Fig. 11). 



The section runs from station 107 off cape Smoke on C. Breton island to station 102 

 of the foregoing section, and crosses the Cabot strait like section XXII, but more 

 westerly.

Salinity. — Coastal water is not found by the observations but intermediate water 

 of low salinitv- (30-water) is found at station 107 from the surface do^\ai to at least 

 60m., thus indicating that coastal water is found at the surface nearer to the coast. 

 This suggestion is confirmed by the pbserv^ations at station 99 of the foregoing section. 

 The intermediate water covers the surface seawards to about station 105, and vertically 

 extends down to about 100m. near the coast. As in the foregoing section the 30-water 

 is predominant and the 31-water only forms a rim close up to the 32 Voo isohaline. 

 This feature seems to indicate that we have to do with water of different origin, the 

 fresher outflowing water near the southern coast and the Salter water in the northern 

 part of the section. From the surface down to 100-l25m. this consists of hank water
