incrcasiiig depth to depths of 150-200 meters and then rose to a slight 

 subsurface maximini at 300 meters. Between 400 end 1000 meters, a unifon^i 

 decrease occured. The greatest temperature variations vrere in the first 

 25 meters, but considerable variation extended to depths of 300 meters. 

 From 400 to 1000 meters, the mean deviation from the mean averaged 0.03° C. 

 Chlorinity values showed a uniform increase ¥/ith increasing depth. The 

 greatest deviations from tho mean occurred in the first 100 meters. Below 

 100 meters, the mean deviation from the mean never exceeded 0.03 °/oo. 



Dens ity. The density of the water at any given level is ^a function L 

 of the temperature and chlorinity and is determined by tiiose values. ' For ^ 

 the area investigated, the isopyaiic lines sho?\fing the di. stribution- of density 

 at the different levels are approximately parallel to tho temperature and 

 chlorinity contours as well as to tho bottom contours. The lowest density 

 values were found at the surface in Horton Sound off tho Yukon Delta. Values 

 of density expressed as Os,t,o of under 23.00 were found in this region. 

 Ma.ximum values of above 25.00 were found just off the Siberian coast and also 

 southT;est of a line extending from the Pribilcf Islands to Unimak Island. 

 The distribution at the 25- and 50-meter levels was analagous to„ .that at 

 the surface, densities increasing frora east to west. Values of about 26.00 

 wore found at these levels in tho deep water south of St. George Island and 

 in the shallow water near tho Siberian coast, V/aters from the' shallov; region 

 of northern Bering Sea we.c quite stable, densities increasing with depth, 

 the increase being very rapid at the transition zone. Only at stations in 

 positions of continuous mixing v/erc densities uniform from top to bottom. 

 In the region of deep water near .Begoslof Island, maximura values of 0^ t o 

 of 27,43 were found at 1000 meters. The stability of the water showed' a' 

 normal decrease with increasing depth in this area.
