Salinih/. — Coastal water is found near the surface at station 99, but the salinity 

 of the surface water increases rapidly to 32-24Voo at station 100. Down to a depth of 

 about 90m. we have, however, a wed'ge of intermediate water, mostly 30-water, dis- 

 playing the outflow of the water-masses from the gulf. Bank water occupies the rest 

 of the section down to 100-125m., consisting from the surface down to 60-T5ni., mostly 

 of inner bank water, while higher salinities are not as commonly distributed. From 

 100-125m. down to 400m. we find slope water, with the 34 Voo isohaline at a depth of 

 30O-35Om., forming a wave to a little above 300m. at station 101. The salinity in 

 400m. runs from 34-70 to 34-80Voo. 



Temperature. — The temperature at station 99 from the surface to the bottom 

 (60m.) is very uniform, falling between 7-35° and 7-5° C. and the wedge of inter- 

 mediate water near the coast seems to have a temperature higher than 5° C. The 

 inner bank water from the surface down to 50-75m. in the northern part of the section 

 mostly has a temperature between 4-5° and 5-0° O., while up to the Newfoundland 

 coast we find temperatures a little below 4° C. in 25 and 50 metres depth. Tlie tem- 

 perature decreases very suddenly when descending into the outer bank water, where 

 we find temperatures between 0-2 and 1-8° C. From 75-lOOm. to about 160m. we find
