Atlantic plankton fauna. However, cold-loving organisms which normally inhabit polar waters have 

 been found in considerable quantities in the area of the Faroes. 



The presence of both organisms indicates that waters of two different origins are inter- 

 mingling here - and this was particularly characteristic of 1953 (Figure 1). Among the warm-water 

 species are CoUozoum groenlandicum, Physophora hydrostatica , Tomopteris helgolandica, Megan- 

 yctlphanes norvegica , Nematoscelis megalops, Limacina retroversa , and the cold-water species 

 include Calanus hype rbo reus , Metridla longa, Scolocithrlx minor , Clione limacina, Themisto 

 llbellula, Limacina helicina.

The positions of the isotherms in May and June 1953 (Figures 2 and 3) show that the cold 

 waters of the East Icelandic current form wedges in the Atlantic waters and at isolated points come 

 right to the surface as cold patches. The polar front is indicated most clearly here. 



It should be noted that despite the presence of warm and cold currents in the Norwegian and 

 Greenland Seas the polar front is not everywhere sufficiently clear (1).
