 (Cross Section O-C, see Figure A-1) 



Water comes in contact with the warm, rising Atlantic Water, the surface 

 runoff, and the inflow from the Barents Sea. Arctic Water is found 

 at all stations between stations 140 and 77. At station 140, close 

 to Franz Josef Land, the cold Arctic Water is overlain by warmer, 

 less saline water which forces the Arctic Water to deeper depths. 

 The T-S plots for section J-J' (Fig. 27) show these water masses 

 in detail. The Arctic Water mass appears to form- a tight locus of 

 points with a salinity of 34,3%o at stations 149, 152, and 154. The 

 temperature isotherms of cross section 0-0' (Fig. A-16) show a typical 

 viev/ of the Arctic Basin with the Arctic Water mass overlying the 

 v/armer Atlantic Water. The temperature isotherms of cross section 

 V-V ' (Fig. A-23) show Arctic Water extending almost to station 53 

 at a depth of 60 meters. The cold tongue of water at 20 meters at 

 stations 31 and 41 closely resembles Arctic Water, but due to low 

 salinity values, this v/ater will not be considered as Arctic Water. 



Arctic Water extends southv/ard from the northernmost line of 

 stations to the northern end of Novaya Zemlya . Eastward, this water 

 mass pinches out as the water shoals and becomes warmer. 



E. Residual V/ater. 



A co]d, residual water which vras formed in previous winters is 

 found in the East Novaya Zem.lya Trough. This water is formed by
