water is an uncustomary water type in the oceanic space under consideration and is 

 maintained only by continuous renewal. The intrustions of the Atlantic water occurs 

 in the form of vertical vortices which break through the polar front, broaden and 

 deepen and if the inflow weakens soon disappear. (Defant, 1930a; Bohnecke, 

 Hentschel and Wattenberg, 1930-32). From Cape Farewell the current bends 

 northwards still keeping also here over the shelf. At first the cold core layer is still 

 present but its temperature rises rapidly indicating stronger mixing with the Atlantic 

 Water penetrating northwards along the continental slope. From about 64° N. the 

 current weakens more and more and near the Davis Strait (about 66-5° N.) there are 

 only traces of the cold core layer found off the Greenland coast. In this region, in all
