of uniform salinity, 10-20 fathoms thick. The curves for Stations — 
10081, 10083, 10084, 10060, 10061, are the reverse, the surface layer 
being nearly uniform with a rapid rise below. As a whole the water 
was freshest near shore, saltest over the outer part of the continental

The salinity sections at the three Stations outside the 100 fathom

the surface, saltest in the intermediate layers, and growing slowly
