of the Sea lying adjacent to the great depths of the Greenland Sea and the 

 Arctic basin. 



N. Zubov (1932) has calculated the distribution of depths in the Barents Sea 

 in percentages as given in Table 28.

1 100 m; 2 100 to 200 m; 3 200 to 300 m; 4 300 to 400 m; 5 400 to 500 m; 6 >500 



m ; 7 Main directions of currents. 



In the opinion of F. Nansen (1922) the floor of the Barents Sea is an ela- 

 borate system of river valleys sunk under the sea surface. In fact if the sea- 

 level were lowered 500 m the whole of the Barents Sea would become dry land. 



Bottom topography 



The bottom topography of the Barents Sea has the following features (Fig. 22). 



In three places troughs below 400 m enter the sea, the first lying between the
