This is formed by waters from the warm Spitsbergen and cold East Greenland currents. In addi- 

 tion to tile branching towards Jan Mayen Island, a part of the Atlantic water finds its way into the 

 Barents Sea (North Cape current, see Figure 2). As has been pointed out, the authors' chart of 

 constant currents in the Norwegian and Greenland Seas differs basically in a number of ways from 

 the chart of Nansen and Helland-Hansen (Figure 3). We will discuss these differences further.

Figure 3 . Chart of constant currents in the Norwegian and Greenland Seas compiled from 

 results of research carried out by the "N. M. Knipovich" Polar Scientific Re- 

 search Institute of Marine Fishery and Oceanography (PINRO) . 1 . Warm 

 currents (largely unmixed Atlantic waters); 2. Cold currents (polar waters); 



3. Currents of mixed waters (which have lost their original characteristics); 



4. Currents of low salinity, warm in summer and cold in winter. 



The principal difference - as has been explained - lies in the feet that the Norwegian (At- 

 lantic) current does not continue in an unbroken stream but splits up into a number of more or less
