 Norwegian Sea. Fig. 192 shows the distribution of salinity at 

 a depth of 100 metres in the southern part of the Norwegian 

 Sea and the northern part of the Atlantic in May 1904. The 

 arrows mark the probable direction of the movements. There 

 are several vortices of different dimensions, one being drawn in
