 BETWEEN 78°27' AND 81°32' NORTH, 176°32' EAST AND 169°50' 

 WEST ACCORDING TO THE OBSERVATIONS OF THE AIRPLANE N-169 

 EXPEDITION, 2 THROUGH 28 APRIL 1941

It must be noted further that the thickness of the warm layer (within the limits of positive 

 temperatures) decreases in a direction towards the periphery. For example the average thickness 

 of the warm layer in the drift regions of the station "North Pole" and icebreaker Sedou and in 

 the region north of Wrangel Island was about 600 m; in the northern part of the Laptev Sea about 

 400 to 520 ra, in the northern part of the Kara Sea about 300 m, and north of the Spitzbergen Franz 

 Joseph Land line about 280 m. Thus the thickness of the Atlantic layer everywhere decreases as it 

 moves into the lesser depths. 



Figure 151 shows an oceanographic section between Franz Joseph Land and Vize Island 

 approximately along 79° north made by us in 1932 on the Knipouich. This drawing gives a 

 graphic idea of how the Atlantic water moves along the St. Anna trough to the south towards Novaya 

 Zemlya.
