F. 1000-meter level : Compared to the levels above, the temperature 

 regime at 1000 meters (Fig. 23) was considerably different. All 

 temperatures were less than 0°C, and the coldest temperatures were 

 found in the southeast portion of the survey region instead of decreasing 

 towards the west. 



The temperature range was relatively small (s=s0.5°C), and the 

 salinity range (Fig. 24) was a mere 0.08 % reflecting the presence 

 of the cold (<0°C), virtually isohaline Arctic Bottom Water at this 

 level. 



The increase in temperatures towards the west could be a reflection 

 of mixing with the warmer waters of the Return Atlantic Current.

to that found at 1000 meters except that temperatures are colder 



(the lowest temperature was -1.01°C) and more uniform. When proceeding 



in a longitudinal direction, there was a tendency for temperatures 



to reach maximum values at about 80°N, and the coldest temperature 



was encountered at station 3 in the southernmost portion of the survey 



region.
